  • extending Bash tab completion: how to handle paths / partial commands?

    - by Rawing
    I've added tab completion for my program to bash. It works quite well, but I don't know how to handle partial completion of words. Example: the user types ./program /home/user/De and presses TAB. This is then completed to ./program /home/user/Desktop/ , but there's now a trailing whitespace after 'Desktop/', which is not what I want. Basically, I need a way of preventing bash from adding whitespace after the completed word. I don't want to use bash's completion for paths.

  • how to fix "BusyBox v1.17.1 (Ubuntu 1:1.17.1-10ubuntu1) built-in shell (ash) Enter 'help' for a list of built-in commands?"

    - by Joseph
    So I was using Ubuntu when suddenly the whole thing froze up and I had to reboot. And from that moment on, the system when it is starting up, prompts this little selection menu: GNU GRUB version 1.99~rc1-13ubuntu3 Ubuntu, with Linux 2.6.38-10-generic ubuntu, with Linux 2.6.38-10-generic (recovery mode) Previous Linux versions Memory test (memtest86+) Memory test (memtest86+, serial console 115200) I have chosen all of the available choices but all I get is another command line system that reads: BusyBox v1.17.1 (Ubuntu 1:1.17.1-10ubuntu1) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs): And honestly I can't do anything with it. Does anyone have any idea of what is going on and how I can get Ubuntu to work again?

  • redirect temporarily STDOUT to another file descriptor, but still to screen

    - by Carlos Campderrós
    I'm making a script that executes some commands inside, and these commands show some output on STDOUT (and STDERR as well, but that's no problem). I need that my script generates a .tar.gz file to STDOUT, so the output of some commands executed in the script also go to STDOUT and this ends with a not valid .tar.gz file in the output. So, in short, it's possible to output the first commands to the screen (as I still want to see the output) but not via STDOUT? Also I would like to keep the STDERR untouched so only error messages appear there. A simple example of what I mean. This would be my script: #!/bin/bash # the output of these commands shouldn't go to STDOUT, but still appear on screen some_cmd foo bar other_cmd baz #the following command creates a tar.gz of the "whatever" folder, #and outputs the result to STDOUT tar zc whatever/ I've tried messing with exec and the file descriptors, but I still can't get it to work: #!/bin/bash # save STDOUT to #3 exec 3>&1 # the output of these commands should go to #3 and screen, but not STDOUT some_cmd foo bar other_cmd baz # restore STDOUT exec 1>&3 # the output of this command should be the only one that goes to STDOUT tar zc whatever/ I guess I'm lacking closing STDOUT after the first exec and reopen it again or something, but I can't find the right way to do it (right now the result is the same as if I didn't add the execs

  • I want a non admin user to install software. What commands do I need to add to sudoers?

    - by Chance
    I want to edit the /etc/sudoers file so that a non-admin user can install software via the Software Center in Linux Mint 10. The reason for this is that I want a user to have the capability to install programs, but not make any other configuration changes to the system. So far I have the following (some of these may not make sense, I was just trying whatever I thought of) username ALL= /usr/bin/aptitude username ALL= /usr/bin/dpkg username ALL= /usr/local/bin/apt-get username ALL= /usr/lib/linuxmint/mintUpdate/mintUpdate.py username ALL= /usr/bin/software-center username ALL= /usr/bin/synaptic So far, it allows me to do updates without asking for my password, but it will not let me install software without entering an admin password. I am aware of this question, How can I set the Software Center to install software for non-root users?, but this goes the route of modifying the PolicyKit, whereas I'm interested in a sudo solution, because it seems a simpler way to go.

  • Parsing special strings within a text (eg. "%var%") ?

    - by RadiantHex
    Hi, I am supplying a Javascript function strings with commands (SVG path commands): eg. "move 10 10 line 50 50" move and line are commands numbers are x, y coordinates I would like to add special strings to these commands, that would instruct the function to use specific variables eg. "move %mouseX%+1 %mouseY%+1" where %mouseX% and %mouseY% would be the mouse x,y coordinates How can I parse and replace these?

  • Under what circumstances is an SqlConnection automatically enlisted in an ambient TransactionScope T

    - by Triynko
    What does it mean for an SqlConnection to be "enlisted" in a transaction? Does it simply mean that commands I execute on the connection will participate in the transaction? If so, under what circumstances is an SqlConnection automatically enlisted in an ambient TransactionScope Transaction? See questions in code comments. My guess to each question's answer follows each question in parenthesis. Scenario 1: Opening connections INSIDE a transaction scope using (TransactionScope scope = new TransactionScope()) using (SqlConnection conn = ConnectToDB()) { // Q1: Is connection automatically enlisted in transaction? (Yes?) // // Q2: If I open (and run commands on) a second connection now, // with an identical connection string, // what, if any, is the relationship of this second connection to the first? // // Q3: Will this second connection's automatic enlistment // in the current transaction scope cause the transaction to be // escalated to a distributed transaction? (Yes?) } Scenario 2: Using connections INSIDE a transaction scope that were opened OUTSIDE of it //Assume no ambient transaction active now SqlConnection new_or_existing_connection = ConnectToDB(); //or passed in as method parameter using (TransactionScope scope = new TransactionScope()) { // Connection was opened before transaction scope was created // Q4: If I start executing commands on the connection now, // will it automatically become enlisted in the current transaction scope? (No?) // // Q5: If not enlisted, will commands I execute on the connection now // participate in the ambient transaction? (No?) // // Q6: If commands on this connection are // not participating in the current transaction, will they be committed // even if rollback the current transaction scope? (Yes?) // // If my thoughts are correct, all of the above is disturbing, // because it would look like I'm executing commands // in a transaction scope, when in fact I'm not at all, // until I do the following... // // Now enlisting existing connection in current transaction conn.EnlistTransaction( Transaction.Current ); // // Q7: Does the above method explicitly enlist the pre-existing connection // in the current ambient transaction, so that commands I // execute on the connection now participate in the // ambient transaction? (Yes?) // // Q8: If the existing connection was already enlisted in a transaction // when I called the above method, what would happen? Might an error be thrown? (Probably?) // // Q9: If the existing connection was already enlisted in a transaction // and I did NOT call the above method to enlist it, would any commands // I execute on it participate in it's existing transaction rather than // the current transaction scope. (Yes?) }

  • How to run some commands after booting from ArchLinux disk? Or how to change some settings in .iso before booting?

    - by Alexander Ovchinnikov
    How to install Arch Linux with traditional installer with only ssh-access to server? There is nice guide: https://wiki.archlinux.org/index.php/Install_from_SSH I try test this on my home vps: Start VPS with any linux bootable cd and login to remote server (vps) wget http://mirrors.kernel.org/archlinux/iso/latest/archlinux-2010.05-netinstall-x86_64.iso dd if=archlinux-2010.05-netinstall-x86_64.iso of=/dev/sda reboot ... I see, it works but without ssh connection... I need make script, which will send this commands after reboot: aif -p partial-configure-network (and write some information about my server ip etc.) /etc/rc.d/sshd start (need to start sshd) echo "sshd: ALL" /etc/hosts.allow (to allow me login to server, by default deny all) passwd (by default its empty, can't login via ssh with empty password) Can I edit .iso or may be /dev/sda? May be I need write script, which will start after system boot and do this things or may be I can set this settings by default and system will start with correct settings (i think its possible at least in 2. and 3.). Thank you!

  • How do I dynamically import a module in App Engine?

    - by Scott Ferguson
    I'm trying to dynamically load a class from a specific module (called 'commands') and the code runs totally cool on my local setup running from a local Django server. This bombs out though when I deploy to Google App Engine. I've tried adding the commands module's parent module to the import as well with no avail (on either setup in that case). Here's the code: mod = __import__('commands.%s' % command, globals(), locals(), [command]) return getattr(mod, command) App Engine just throws an ImportError whenever it hits this. And the clarify, it doesn't bomb out on the commands module. If I have a command like 'commands.cat' it can't find 'cat'.

  • Visual Studio Little Wonders: Quick Launch / Quick Access

    - by James Michael Hare
    Once again, in this series of posts I look at features of Visual Studio that may seem trivial, but can help improve your efficiency as a developer. The index of all my past little wonders posts can be found here. Well, my friends, this post will be a bit short because I’m in the middle of a bit of a move at the moment.  But, that said, I didn’t want to let the blog go completely silent this week, so I decided to add another Little Wonder to the list for the Visual Studio IDE. How often have you wanted to change an option or execute a command in Visual Studio, but can’t remember where the darn thing is in the menu, settings, etc.?  If so, Quick Launch in VS2012 (or Quick Access in VS2010 with the Productivity Power Tools extension) is just for you! Quick Launch / Quick Access – find a command or option quickly For those of you using Visual Studio 2012, Quick Launch is built right into the IDE at the top of the title bar, near the minimize, maximize, and close buttons: But do not despair if you are using Visual Studio 2010, you can get Quick Access from the Productivity Power Tools extension.  To do this, you can go to the extension manager: And then go to the gallery and search for Productivity Power Tools and install it.  If you don’t have VS2012 yet, then the Productivity Power Tools is the next best thing.  This extension updates VS2010 with features such as Quick Access, the Solution Navigator, searchable Add Reference Dialog, better tab wells, etc.  I highly recommend it! But back to the topic at hand!  In VS2012 Quick Launch is built into the IDE and can be accessed by clicking in the Quick Launch area of the title bar, or by pressing CTRL+Q.  If you have VS2010 with the PPT installed, though, it is called Quick Access and is accessible through View –> Quick Access: Regardless of which IDE you are using, the feature behaves mostly the same.  It allows you to search all of Visual Studio’s commands and options for a particular topic.  For example, let’s say you want to change from tabs to tabs expanded to spaces, but don’t remember where that option is buried.  You can bring up Quick Launch / Quick Access and type in “tabs”: And it brings up a list of all options on tabs, you can then choose the one appropriate to you and click on it and it will take you right there! A lot easier than diving through the options tree to find what you are looking for!  It also works on menu commands, for example if you can’t remember how to open the Output window: It shows you the menu items that will get you to the Output window, and (if applicable) the keyboard shortcuts.  Again, clicking on one of these will perform the action for you as well. There are also some tasks you can perform directly from Quick Launch / Quick Access.  For example, perhaps you are one of those people who like to have the line numbers in your editor (I do), so let’s bring up Quick Launch / Quick Access and type “line numbers”: And let’s select Turn Line Numbers On, and now our editor looks like: And Voila!  We have line numbers in VS2010.  You can do this in VS2012 too, but it takes you to the option settings instead of directly turning them off and on.  There are bound to be differences between the way the two editors organize settings and commands, but you get the point. So, as you can see, the Quick Launch / Quick Access feature in Visual Studio makes it easy to jump right to the options, commands, or tasks you are interested in without all the digging. Summary An IDE as powerful as Visual Studio has so many options and commands that it can be confusing to remember how to find and invoke them.  Quick Launch (Quick Access in VS2010 with Productivity Power Tools extension) is a quick and handy way to jump to any of these options, commands, or tasks quickly without having to remember in what menu or screen they are buried!  Technorati Tags: C#,CSharp,.NET,Little Wonders,Visual Studio,Quick Access,Quick Launch

  • Label in PyQt4 GUI not updating with every loop of FOR loop

    - by user297920
    I'm having a problem, where I wish to run several command line functions from a python program using a GUI. I don't know if my problem is specific to PyQt4 or if it has to do with my bad use of python code. What I wish to do is have a label on my GUI change its text value to inform the user which command is being executed. My problem however, arises when I run several commands using a for loop. I would like the label to update itself with every loop, however, the program is not updating the GUI label with every loop, instead, it only updates itself once the entire loop is completed, and displays only the last command that was executed. I am using PyQt4 for my GUI environment. And I have established that the text variable for the label is indeed being updated with every loop, but, it is not actually showing up visually in the GUI. Is there a way for me to force the label to update itself? I have tried the update() and repaint() methods within the loop, but they don't make any difference. I would really appreciate any help. Thank you. Ronny. Here is the code I am using: # -*- coding: utf-8 -*- import sys, os from PyQt4 import QtGui, QtCore Gui = QtGui Core = QtCore # ================================================== CREATE WINDOW OBJECT CLASS class Win(Gui.QWidget): def __init__(self, parent = None): Gui.QWidget.__init__(self, parent) # --------------------------------------------------- SETUP PLAY BUTTON self.but1 = Gui.QPushButton("Run Commands",self) self.but1.setGeometry(10,10, 200, 100) # -------------------------------------------------------- SETUP LABELS self.label1 = Gui.QLabel("No Commands running", self) self.label1.move(10, 120) # ------------------------------------------------------- SETUP ACTIONS self.connect(self.but1, Core.SIGNAL("clicked()"), runCommands) # ======================================================= RUN COMMAND FUNCTION def runCommands(): for i in commands: win.label1.setText(i) # Make label display the command being run print win.label1.text() # This shows that the value is actually # changing with every loop, but its just not # being reflected in the GUI label os.system(i) # ======================================================================== MAIN # ------------------------------------------------------ THE TERMINAL COMMANDS com1 = "espeak 'senntence 1'" com2 = "espeak 'senntence 2'" com3 = "espeak 'senntence 3'" com4 = "espeak 'senntence 4'" com5 = "espeak 'senntence 5'" commands = (com1, com2, com3, com4, com5) # --------------------------------------------------- SETUP THE GUI ENVIRONMENT app = Gui.QApplication(sys.argv) win = Win() win.show() sys.exit(app.exec_())

  • Data loss through permissions change?

    - by charliehorse55
    I seem to have deleted some files on my media drive, simply by changing the permissions. The Story I have many operating systems installed on my computer, and constantly switch between them. I bought a 1TB HD and formatted it as HFS+ (not journaled). It worked well between OSX and all of my linux installations while having much better metadata support than NTFS. I never synced the UIDs for my operating systems so the permissions were always doing funny things. Yesterday I tried to fix the permissions by first changing the UIDs of the other operating systems to match OSX, and then changing the file ownership of all files on the drive to match OSX. About 50% of the files on the drive were originally owned by OSX, the other half were owned by the various linux installations. I started to try and change the file permissions for the folders, and that's when it went south. The Commands These commands were run recursively on the one section of the drive. sudo chflags nouchg sudo chflags -N sudo chown myusername sudo chmod 666 sudo chgrp staff The Bad Sometime during the execution of these commands, all of the files belonging to OSX were deleted. If a folder had linux based files it would remain intact but any folder containing exclusively OSX files was erased. If a folder containing linux files also contained a subfolder with only OSX files, the sub folder would remain but is inaccesible and displays a file size of 0 bytes. Luckily these commands were only run on the videos folder, I also have a music folder with the same issue but I did not execute any of these commands on it. Effectively I have examples of the file permissions for all 3 states - the linux files before and after, and the OSX files before. OSX File Before -rw-r--r--@ 1 charliehorse 1000 3634241 15 Nov 2008 /path/to/file com.apple.FinderInfo 32 Linux File before: -rw-r--r--@ 1 charliehorse 1000 5321776 20 Sep 2002 /path/to/file/ com.apple.FinderInfo 32 Linux File After (Read only): (Different file, but I believe the same permissions originally) -rw-rw-rw-@ 1 charliehorse staff 366982610 17 Jun 2008 /path/to/file com.apple.FinderInfo 32 These files still exist so if there are any other commands to run on them to determine what has happened here, I can do that. EDIT Running ls on one of the "empty" deleted OSX folders yields this: ls: .: Permission denied ls: ..: Permission denied ls: subdirA: Permission denied ls: subdirB: Permission denied ls: subdirC: Permission denied ls: subdirD: Permission denied I believe my files might still be there, but the permissions are screwed.

  • sequential SSH command execution not working in Ubuntu/Bash

    My requirement is I will have a set of commands that needs to be executed in a text file. My Shell script has to read each command, execute and store the results in a separate file. Here is the snippet which does the above requirement. while read command do echo 'Command :' $command >> "$OUTPUT_FILE" redirect_pos=`expr index "$command" '>>'` if [ `expr index "$command" '>>'` != 0 ];then redirect_fn "$redirect_pos" "$command"; else $command state=$? if [ $state != 0 ];then echo "command failed." >> "$OUTPUT_FILE" else echo "executed successfully." >> "$OUTPUT_FILE" fi fi echo >> "$OUTPUT_FILE" done < "$INPUT_FILE" Sample Commands.txt will be like this ... tar -rvf /var/tmp/logs.tar -C /var/tmp/ Commands_log.txt gzip /var/tmp/logs.tar rm -f /var/tmp/list.txt This is working fine for commands which needs to be executed in local machine. But When I am trying to execute the following ssh commands only the 1st command getting executed. Here are the some of the ssh commands added in my text file. ssh uname@hostname1 tar -rvf /var/tmp/logs.tar -C /var/tmp/ Commands_log.txt ssh uname@hostname2 gzip /var/tmp/logs.tar ssh .. etc When I am executing this in cli it is working fine. Could anybody help me in this?

  • Communicating via Command Mode with IBM HS22 IMM via AMM

    - by MikeyB
    On previous model blades that contained a BMC, I was able to communicate from our external management station via pass-through commands to the BMC to do things such as power blades on/off, set VPD parameters, reboot the BMC, etc. Now on the HS22, a bunch of things happen differently. For example, we can no longer use the same pass-through commands to write VPD information pages and have them persist across reboots of the IMM - it looks as though those VPD pages are populated from information contained in the IMM. How do we use the Advanced Settings Utility from an external host to communicate with HS22 IMMs? Alternatively, what TCP Command Mode commands do we need to send to the AMM to communicate with the IMM? For our purposes, we specifically cannot communicate with the IMM from the blade itself. Specific example: When I send a pass-thru IPMI command via the AMM to the blade BMC to write information (such as MTM, Serial) into VPD page 0x10, it persists on blades with a BMC (HS21 for example). I can send the same IPMI command to write data to the VPD page on the HS22, however it does not persist across reboots of the IMM. What IPMI commands do I need to send to the IMM? What IPMI commands are asu sending when it sets the MTM & Serial?

  • Reconfiguring, then deleting obsolete pagefile.sys from C: in one go using a batch script

    - by DanielSmedegaardBuus
    I'm trying to set up an automated script for a Windows XP installer. It's a batch script that runs on first boot after installation, and among the things I'm trying to accomplish, is removing the pagefile from C: entirely, and putting a 16-768 MB pagefile on D: instead. Here're my batch file instructions: echo === Creating new page file on D: ... cscript %windir%\system32\pagefileconfig.vbs /create /i 16 /m 768 /vo d: >nul echo. echo === Removing old page file from C: ... cscript %windir%\system32\pagefileconfig.vbs /delete /vo C: attrib -s -h c:\pagefile.sys del c:\pagefile.sys My problem is that while these are sane commands, the removal of the pagefile on C: requires me to reboot before those commands succeed.b Or, in other words — I have to first create the D: pagefile, then reboot and delete the c:\pagefile.sys file, or I'm stuck with a c:\pagefile.sys file which isn't even recognized by Windows itself (it'll just say that there's a page file on D:, and that C: has no pagefile at all). Obviously because already some pages are written to the C:\pagefile.sys file. So how would I go about accomplishing this in one go? Or, in two gos, if this is "batch scriptable" :) TIA, Daniel :) EDIT: I should probably clarify: Running those commands above are all valid, but they'll only succeed fully if I re-run the "attrib" and "del" commands at next boot. The C: pagefile is in use at the time, so I cannot delete the file it uses, and Windows itself won't remove it when I configure it to not use C: as a page file drive. Instead, it'll leave an orphaned c:\pagefile.sys file behind (which is really large). I don't necessarily need this to work in one go, registering the last two commands to run after a reboot would also be great :)

  • Is there a unix command to output time elapsed during a command?

    - by Olivier Lacan
    I love using time to find out how long a command took to execute but when dealing with commands that execute sub-commands internally (and provide output that allows you to tell when each of those sub-commands start running) it would be really great to be able to tell after what number of seconds (or milliseconds) a specific sub-command started running. When I say sub-command, really the only way to distinguish these from the outside is anything printed to standard out. Really this seems like it should be an option to time.

  • SFTP logging: is there a way?

    - by Darryl Hein
    I'm wondering if there is a way to log commands received by the server. It can be all SSH commands, as long as it includes information on commands related to file transfer. I'm having issues with an SFTP client and the creator is asking for logs, but I am unable to find any existing logs. I'm looking to log on both or either CentOS or OS X (although I suspect if it's possible, it'd be similar on both).

  • Fake demostration software for command line

    - by Joe
    I'm looking for some software that would be useful for giving demonstrations. I regularly have to show the effects of scrips ect to classes while talking about their effects, and equaly regularly I have finger trouble and have to rewrite various commands - wasting class time and general energy. I'd like to be able to record a sequence of commands in advance, and then play them back at the speed of my choosing. So I might have a file that containes the commands: echo "hello world!" ls ls -l ls -l | sort I'd like to be able to play these commands back by typing similar ones in. So I'd have a blinking command prompt and if I typed 'echo "hxxx' the command prompt would read home$echo "hell and if I typed any other letters the terminal would fill up with the remainder of the command until I press enter, when it executes the command. The point is that even if I screw up the command when typing it, the command that I'd prepared in advance would be executed. My question is - does similar software exist for giving demonstrations? or even, is this an easy thing to script up...? EDIT - two quick things first of all I'm on osx - but it would be nice to get a general solution for other people who arrive here from google. and second a lot of the comments/answers are concentrating on, in effect, making it fast and easy to enter long commands by means of hotkeys and the like. Actually I'd like it to at least look like I'm typing live - that's why I put in the bit about the one-to-one keymapping, but I don't think I explained that quite as well as I could have...

  • Adding group + items in Windows Explorer's pop-up menu?

    - by OverTheRainbow
    An application I use regularly is command-line based, and I would like to add the most used commands in the Windows Explorer's context menu that pops up when right-clicking on a file or folder. From what I read, a lot of programs in that menu are COM applications. Is there an easier way to add commands to the menu, as an alternative to opening a DOS box and typing commands? Ideally, it should work for XP, Vista, and 7.

  • How to write more than one line in a launcher

    - by seraex
    How can I run three commands in a launcher? My commands are cd /home/seraex/MyDoc rm MyDoc.tgz tar cfz MyDoc.tgz * which will go to my documents folder and delete old backup and make a new backup. At the moment I make a text file and then make a launcher and point it to the file, but I want to delete the file and make the launcher run the commands directly. I'm using ubuntu 10.10 ' ubuntu site says 'Unfortunately launchers do not have access to the Bash environment so you cannot just include the multi commands' when i ggole chaining in launchers. thanks, admin may delete the question '

  • Visual Studio 2010 Extension Manager (and the new VS 2010 PowerCommands Extension)

    - by ScottGu
    This is the twenty-third in a series of blog posts I’m doing on the VS 2010 and .NET 4 release. Today’s blog post covers some of the extensibility improvements made in VS 2010 – as well as a cool new "PowerCommands for Visual Studio 2010” extension that Microsoft just released (and which can be downloaded and used for free). [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] Extensibility in VS 2010 VS 2010 provides a much richer extensibility model than previous releases.  Anyone can build extensions that add, customize, and light-up the Visual Studio 2010 IDE, Code Editors, Project System and associated Designers. VS 2010 Extensions can be created using the new MEF (Managed Extensibility Framework) which is built-into .NET 4.  You can learn more about how to create VS 2010 extensions from this this blog post from the Visual Studio Team Blog. VS 2010 Extension Manager Developers building extensions can distribute them on their own (via their own web-sites or by selling them).  Visual Studio 2010 also now includes a built-in “Extension Manager” within the IDE that makes it much easier for developers to find, download, and enable extensions online.  You can launch the “Extension Manager” by selecting the Tools->Extension Manager menu option: This loads an “Extension Manager” dialog which accesses an “online gallery” at Microsoft, and then populates a list of available extensions that you can optionally download and enable within your copy of Visual Studio: There are already hundreds of cool extensions populated within the online gallery.  You can browse them by category (use the tree-view on the top-left to filter them).  Clicking “download” on any of the extensions will download, install, and enable it. PowerCommands for Visual Studio 2010 This weekend Microsoft released the free PowerCommands for Visual Studio 2010 extension to the online gallery.  You can learn more about it here, and download and install it via the “Extension Manager” above (search for PowerCommands to find it). The PowerCommands download adds dozens of useful commands to Visual Studio 2010.  Below is a screen-shot of just a few of the useful commands that it adds to the Solution Explorer context menus: Below is a list of all the commands included with this weekend’s PowerCommands for Visual Studio 2010 release: Enable/Disable PowerCommands in Options dialog This feature allows you to select which commands to enable in the Visual Studio IDE. Point to the Tools menu, then click Options. Expand the PowerCommands options, then click Commands. Check the commands you would like to enable. Note: All power commands are initially defaulted Enabled. Format document on save / Remove and Sort Usings on save The Format document on save option formats the tabs, spaces, and so on of the document being saved. It is equivalent to pointing to the Edit menu, clicking Advanced, and then clicking Format Document. The Remove and sort usings option removes unused using statements and sorts the remaining using statements in the document being saved. Note: The Remove and sort usings option is only available for C# documents. Format document on save and Remove and sort usings both are initially defaulted OFF. Clear All Panes This command clears all output panes. It can be executed from the button on the toolbar of the Output window. Copy Path This command copies the full path of the currently selected item to the clipboard. It can be executed by right-clicking one of these nodes in the Solution Explorer: The solution node; A project node; Any project item node; Any folder. Email CodeSnippet To email the lines of text you select in the code editor, right-click anywhere in the editor and then click Email CodeSnippet. Insert Guid Attribute This command adds a Guid attribute to a selected class. From the code editor, right-click anywhere within the class definition, then click Insert Guid Attribute. Show All Files This command shows the hidden files in all projects displayed in the Solution Explorer when the solution node is selected. It enhances the Show All Files button, which normally shows only the hidden files in the selected project node. Undo Close This command reopens a closed document , returning the cursor to its last position. To reopen the most recently closed document, point to the Edit menu, then click Undo Close. Alternately, you can use the CtrlShiftZ shortcut. To reopen any other recently closed document, point to the View menu, click Other Windows, and then click Undo Close Window. The Undo Close window appears, typically next to the Output window. Double-click any document in the list to reopen it. Collapse Projects This command collapses a project or projects in the Solution Explorer starting from the root selected node. Collapsing a project can increase the readability of the solution. This command can be executed from three different places: solution, solution folders and project nodes respectively. Copy Class This command copies a selected class entire content to the clipboard, renaming the class. This command is normally followed by a Paste Class command, which renames the class to avoid a compilation error. It can be executed from a single project item or a project item with dependent sub items. Paste Class This command pastes a class entire content from the clipboard, renaming the class to avoid a compilation error. This command is normally preceded by a Copy Class command. It can be executed from a project or folder node. Copy References This command copies a reference or set of references to the clipboard. It can be executed from the references node, a single reference node or set of reference nodes. Paste References This command pastes a reference or set of references from the clipboard. It can be executed from different places depending on the type of project. For CSharp projects it can be executed from the references node. For Visual Basic and Website projects it can be executed from the project node. Copy As Project Reference This command copies a project as a project reference to the clipboard. It can be executed from a project node. Edit Project File This command opens the MSBuild project file for a selected project inside Visual Studio. It combines the existing Unload Project and Edit Project commands. Open Containing Folder This command opens a Windows Explorer window pointing to the physical path of a selected item. It can be executed from a project item node Open Command Prompt This command opens a Visual Studio command prompt pointing to the physical path of a selected item. It can be executed from four different places: solution, project, folder and project item nodes respectively. Unload Projects This command unloads all projects in a solution. This can be useful in MSBuild scenarios when multiple projects are being edited. This command can be executed from the solution node. Reload Projects This command reloads all unloaded projects in a solution. It can be executed from the solution node. Remove and Sort Usings This command removes and sort using statements for all classes given a project. It is useful, for example, in removing or organizing the using statements generated by a wizard. This command can be executed from a solution node or a single project node. Extract Constant This command creates a constant definition statement for a selected text. Extracting a constant effectively names a literal value, which can improve readability. This command can be executed from the code editor by right-clicking selected text. Clear Recent File List This command clears the Visual Studio recent file list. The Clear Recent File List command brings up a Clear File dialog which allows any or all recent files to be selected. Clear Recent Project List This command clears the Visual Studio recent project list. The Clear Recent Project List command brings up a Clear File dialog which allows any or all recent projects to be selected. Transform Templates This command executes a custom tool with associated text templates items. It can be executed from a DSL project node or a DSL folder node. Close All This command closes all documents. It can be executed from a document tab. How to temporarily disable extensions Extensions provide a great way to make Visual Studio even more powerful, and can help improve your overall productivity.  One thing to keep in mind, though, is that extensions run within the Visual Studio process (DevEnv.exe) and so a bug within an extension can impact both the stability and performance of Visual Studio.  If you ever run into a situation where things seem slower than they should, or if you crash repeatedly, please temporarily disable any installed extensions and see if that fixes the problem.  You can do this for extensions that were installed via the online gallery by re-running the extension manager (using the Tools->Extension Manager menu option) and by selecting the “Installed Extensions” node on the top-left of the dialog – and then by clicking “Disable” on any of the extensions within your installed list: Hope this helps, Scott
