• find grep pipe and ampersand

  - by HKK

  I am using cygwin to find a file on the cygdrive. However I need to suppress the permission denied messages (otherwise the results get hidden in the error messages). The following command works: find -name 'myfile.*' |& grep -v "Permission denied" I don't understand why the ampersand needs to be put into this command, would have expected this to work but it doesn't. find -name 'myfile.*' | grep -v "Permission denied" Please explain the meaning of the ampersand.

• Watch syntax help

  - by Jason

  In my Systems Programming class, there are weekly programming experiments, and I'm having trouble with the current one. The objective is to write a C program that slowly writes a string of text to a file, metered by usleep() in a 100 count for loop. The goal of the experiment is to observe the file size buffer in action via the watch command. However, I can't get it to work using watch -d ./output What syntax do I need for the watch command to see the changes made to the file size?

• How to find out console equivalents of Ubuntu System Settings GUI?

  - by user4514

  How do I in general find out, what the very nice "System Settings GUI" in Ubuntu (say 12.04) does and how to replicate the changes in command line? Many people ask questions like "how to change the keyboard rate using command line", and often the answers do not help and are hard to find. What is the easiest way to find out, what the GUI is actually changing (for various types of settings. I.e. keyboard layout, rate, mouse, network, ...)

• perform command substitution in MS-DOS

  - by wiggin200

  I wonder how you can make in MS-DOS a command substitution Command substitution is a very powerful concept of the UNIX shell. It is used to insert the output of one command into a second command. E.g. with an assignment: $ today=$(date) # starts the "date" command, captures its output $ echo "$today" Mon Jul 26 13:16:02 MEST 2004 This can also be used with other commands besides assignments: $ echo "Today is $(date +%A), it's $(date +%H:%M)" Today is Monday, it's 13:21 This calls the date command two times, the first time to print the week-day, the second time for the current time. I need to know to do that in MS-DOS, (I already know that there is a way to perform something like that using as part of the for command, but this way is much more obfuscated and convoluted

• How do I Send Email from the Command Line?

  - by Joseph Pecoraro

  I would like to quickly send email from the command line. I realize there are probably a number of different ways to do this. I'm looking for a simple way to do this from a linux terminal (likely a bash shell but anything should do) and an alternative way to do this on Windows. I want to be able to whip up an email right on the command line or have the flexibility to pipe the message into the command line program. How would you go about doing this? If you have small scripts that would be fine as well. Thanks in advance.

• Open ms word in "compare document" mode from command prompt.

  - by arraku-gmail-com

  I am working on a web project where client needs a functionality to first upload some MS word document & then he can compare any two of the uploaded documents. The idea I came up with is to first make the documents available using WEBDAV & then open both documents using command line with "Compare side by side" option. In this way he will be able to compare & modify two documents. The problem is, I am not able to find any command which can be run from command prompt to open two documents in compare mode. Also, if you know any other way to achieve this functionality then please share it with me. Thanks!

• XUbuntu: Open file browser via "run command" menu

  - by mbelow

  In older Xubuntu versions, if I entered a path to a directory in the "run command" dialog, a thunar-window was opened showing this directory. I found that to be very handy if I would open f.e.g "/tmp", I just needed to press WindowsKey+r, enter /tmp and press enter, there I was. This was also great for URLs (ftp, http etc) Unfortunately, since 12.04, this doesn't work anymore. It seem as if the "run command" is now integrated with the program finder. It still works when I type "thunar ftp://...." or "thunar /tmp", but it's a bit tedious now. Is there a way to restore the old behavior? Note: I'm running a german localization of Xubuntu - I hope I translated "run command" and "program finder" correctly...

• Implementing Command Pattern in Web Application

  - by KingOfHypocrites

  I'm looking to implement the command pattern in a web application (asp.net c#)... Since the commands come in text format from the client, what is the best way to translate the string to a command object? Should I use reflection? Currently I just assume the command that comes in matches the file name of a user control. This is a bit of a hack. Rather than have a select case statement that says if string = "Dashboard" then call Dashboard.Execute(), is there a pattern for working with commands that originate as strings?

• What command are my volume keys running?

  - by user2787904

  In Unity I use my ThinkPad hot keys to change the volume. I need to know the command that these keys run so that I can bind it in my window manager. I have tried using amixer but could not change the volume through command line amixer set Master 10%- amixer: Unable to find simple control 'Master',0 amixer scontrols: Simple mixer control 'IEC958',0 amixer set 'IEC958' 50%- amixer: Invalid command! So obviously this is not what Unity is running. I have tried changing the default sound card as well but that didn't help.

• Is it possible to save output from a command to a file subsequent the command already has been executed?

  - by NES

  Does an elegant way exists to save the output of a command subsequent to a file as long as the terminal window is open? I mean once the command has been executed in the terminal. The output is still there in terminal. Now i could copy & paste all the lines and save it to a file. But perhaps does a method exist to somehow write the output buffer of a terminal window to a file or even better the output of an already executed command?

• How to generate `AllowDeactivateGrabs` in command line ?

  - by boffin

  I am using XFCE-Ubuntu and do a lot of my development work there. In my case, when I sometimes use Xilinx ISE, the mouse cursor hangs as a Grab pointer and then stops responding. The entire X environment becomes unusable and I have to kill it and restart. This is becoming a serious annoyance. I saw this bug: AllowDeactivateGrabs is broken I see that sending AllowDeactivateGrabs in command line can kill the Grab. In my case, I am doing this on a remote server, so it is the application in the remote server (over X2GO) getting messed up. I am able to login in command line and kill X. Is there a way to generate AllowDeactivateGrabs in command line ? So I dont mess up my other applications and potentially lose data.

• How can I connect to a Windows server using a Command Line Interface? (CLI)

  - by HopelessN00b

  Especially with the option to install Server Core in Server 2008 and above, connecting to Windows servers over a CLI is increasingly useful ability, if not one that's very widespread amongst Windows administrators. Practically every Windows GUI management tool has an option to connect to a remote computer, but there is no such option present in the built-in Windows CLI (cmd.exe), which gives the initial impression that this might not be possible. Is it possible to remotely management or administer a Windows Server using a CLI? And if so, what options are there to achieve this?

• Firefox 3.6.3 on Snow Leopard 10.6.3 - symbolic link to command line binary doesn't work?

  - by David Watson

  I have Firefox 10.6.3 installed on Mac OS X Snow Leopard from the DMG. I can run firefox from the terminal using /Applications/Firefox.app/Contents/MacOS/firefox-bin. However, if I create a symbolic link: sudo ln -s /Applications/Firefox.app/Contents/MacOS/firefox-bin /bin/firefox then it refuses to run, or at least display. When I issue "firefox" from the terminal, I can see the process in top, but never get the GUI to appear. :/ = ls -lr /bin/firefox lrwxr-xr-x 1 root wheel 52 May 5 15:19 /bin/firefox - /Applications/Firefox.app/Contents/MacOS/firefox-bin Any ideas?

• How do you set the Scheduled Tasks "Run only if logged in" option from the command line?

  - by Paul K

  I want to create some tasks with the "Run only if logged in" option set, but using a batch file, as you can in the user interface version of the schtasks.exe tool. I'm doing this so I don't have to specify a password, either in the batch file, or when the batch file is run... I would use /ru System but I can't because the tool I'm automating (SyncToy 2.1) won't run with that account because I am hitting a network drive... Also, I noticed that Google Chrome sets up some tasks with this option set during installation, so I'm thinking there must be a way...

  The obvious-to-me approaches fail. # format h: /fs:ntfs /q /y /V:512MB Disk Invalid parameter - Disk # format h: /fs:ntfs /q /y /V:"512MB Disk" Invalid parameter - Disk" # format h: /fs:ntfs /q /y /V:"512MB\ Disk" Invalid parameter - Disk" # format h: /fs:ntfs /q /y /V:512MB\ Disk Invalid parameter - Disk Okay, so label works after-the fact. # label h: 512MB Disk # But how to do it using format? Am I missing some kind of escape sequence?

• Anyone know of a command-line torrent client to run on a server?

  - by DJTripleThreat

  I have an account with a torrent site that gives and takes credits when you upload/download respectively. My ideal setup to keep my credits going would be some kind of media box that keeps and manages my music and videos etc. Ideally, I'd like this to be a headless box that I could just telnet into and have it run torrents that way. This server would be running ubuntu server by the way.

• How can I load an image directly into the Windows clipboard from the command line?

  - by Daniel J. Pritchett

  My dad asked me how he could script the pasting/inclusion of images in various applications. I'm sure I could script out some quick <img src=... HTML but I believe he's also looking to do this in Windows GUI applications like Word or Outlook. So, how could I script a process with the following inputs and outputs: load_image_into_clipboard_script.cmd sample_file.jpg Clipboard now contains the aforementioned image file, just as if I'd e.g. opened it in Paint and done a Select All - Copy. I noticed there's a clip.exe utility with Vista/Win2003 and up; perhaps that will be a useful intermediary?
