  • After installing Ubuntu how do I get rid of unity and go back to gnome?

    - by aseq
    After I have installed the newest Ubuntu LTS release (12.04, still in beta though) I am greeted with an unfamiliar and difficult to use desktop environment. I believe it is called unity. However I have used gnome for a decade and a half and I would not like to move to this new and (for me) unusable desktop environment. What is a quick and easy way to remove (most) of unity and bring back gnome, as well as configure my display manager to load gnome by default with the environment as close as possible to the way it was before?

  • Superscope DHCP leases and configuration set up

    - by Vdub
    Hello I wanted to see if someone could help with a network problem I am having. Right now we have a super-scope and scopes of 192.168.50.1 and 192.168.51.1, as of now both are activated but only 192.168.50.1 is handing our leases, 192.168.51 wont. here is a summary of our network Gateway: watchguard firebox x750e for our router/gateway at 192.168.50.1 I set up as a secondary IP address 192.168.51.1 Server: Server 2008 r2 standard, running our DNS @ 192.168.50.242 and 8.8.8.8 as a secondary, AD, and DHCP. On that NIC card i have 192.168.50.242 as the IP address and 192.168.51.242 as a secondary. 192.168.50.1 as the default gateway and 192.168.51.1 as a secondary. Im am not very knowledgeable at this but as far as i have researched after adding a super scope and activating scopes, they should automatically start handing out addresses and I cant figure out why only one does. any help at all would be appreciated.

  • Dual monitor not working completely in 12.10 after upgrade

    - by Mark Baldridge
    At 12.04, dual monitors worked perfectly. After upgrading to 12.10, the primary monitor works, the second monitor only partly works. I am sure there is some difference between the releases that I have missed setting properly. System settings - Displays show both correctly as Acer 22" monitors at 1680x1050 (16:10). An icon on monitor 2 is present, but elongated; almost an artifact, since other icons on the primary screen are absent, but this one icon is there on th second monitor. Selecting the icons on both screens exist. Painting is weird on monitor 2. Launcher exists and works on both screens, but even with sticky edges off, the cursor stops at the left edge of monitor 2. Clicking on text editor on screen 2 launcer will launch gedit there. If I drag it, it leaves a trail of after images like repaint is failing. If I drive the cursor on the launcher, the help tags like "LibreOffice Writer" appear, but stay on screen unless I drag the active gedit window over them. Then part of the help bubbles are overwritten, leaving behind after images of the gedit window on screen. What is really fascinating is that the System settings - Displays is now ignoring monitor selection, after allowing it earlier. Just before this, the help popup which said "Select a monitor to change its properties; drag to rearrange its placement" actually let me do that. Maybe a trick of where I grab the edge of the monitor in the Displays setting. I just found a working handle. When I drag monitor 1 to the right of monitor 2, "Apply" and confirm, both monitors work normally (although the right monitor lets the cursor slide off the right edge onto the left edge of monitor 1 - which sounds correct). Painting of windows does not leave an after image. However, success is only temporary. The setting survives the reboot, but painting on the left monitor, now monitor 2, now replicates the issues from before. The after image of the gedit window and the small window for "Are you sure you want to close all programs and restart the computer?" are still on monitor 2 (on the left now), even though they are not real windows, nor do they have processes behind them. Curiously, in Displays, the "green" monitor on the left in the display window is matched by the right monitor color in the monitor upper left corner. Probably makes sense as the one on the right is now monitor 1. If I repeat the "drag the left monitor to the right of the right monitor on the "Displays" window, things are oriented properly, with no display artifacts as I drag windows around either screen. Also the description bubbles that pop up are overwritten on both screens, so none of those artifacts either. This goodness does not survive a reboot, however. Have not tried logging out and back in. All of this after positing that the motherboard VGA and HDMI ports could have been the issue. So, I installed an e-GeForce 7600 GT Dual DVI (I know the web thinks it is not DVI, but VGA, but the connectors are DVI). No change to the weird behavior. The good parts continue to work, the weirdness also works, and swapping monitor positions seems to cure the issue. So, is there a setting I have missed? Given "swapping" monitor 1 and 2 on the System Settings... - Displays makes it work, just not across boot, I suspect so.

  • NTFS write speed really slow (<15MB/s)

    - by Zulakis
    I got a new Seagate 4TB harddrive formatted with ntfs using parted /dev/sda > mklabel gpt > mkpart pri 1 -1 mkfs.ntfs /dev/sda1 When copying files or testing writespeed with dd, the max writespeed I can get is about 12MB/s. The harddrive should be capable of atleast 100MB/s. top shows high cpu usage for the mount.ntfs process. The system has a AMD dualcore. This is the output of parted /dev/sda unit s print: Model: ATA ST4000DM000-1F21 (scsi) Disk /dev/sda: 7814037168s Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 2048s 7814035455s 7814033408s pri The used kernel is 3.5.0-23-generic.

  • How to Install WebLogic 12c ZIP on Linux

    - by Bruno.Borges
    I knew that WebLogic had this small ZIP distribution, of only 184M, but what I didn't know was that it is so easy to install it on Linux machines, specially for development purposes, that I thought I had to blog about it. You may want to check this blog, where I found the missing part on this how to, but I'm blogging this again because I wanted to put it in a simpler way, straight to the point. And if you are looking for a how to for Mac, check Arun Gupta's post.  So, here's the step-by-step: 1 - Download the ZIP distribution (don't worry if your system is x86_64)Don't forget to accept the OTN Free Developer License Agreement! 2 - Choose where to install your WebLogic server and your domain, and set as your MW_HOME environment variableI will use /opt/middleware/weblogic for this how to export MW_HOME=/opt/middleware/weblogicMake sure this path exists in your system. 'mydomains' will be used to keep your WebLogic domain. mkdir -p $MW_HOME/mydomain 3 - If you don't have your JAVA_HOME environment variable still configured, do it. Point it to where your JDK is installed. export JAVA_HOME=/usr/lib/jvm/default-java 4 - Unzip the downloaded file into MW_HOME unzip wls1211_dev.zip -d $MW_HOME 5 - Go to that directory and run configure.sh cd $MW_HOME ./configure.sh 6 - Call the setEnvs.sh script . $MW_HOME/wlserver/server/bin/setWLSEnv.sh7 - Create your development domain. It will ask you for username and password. I like to use weblogic / welcome1cd $MW_HOME/mydomain $JAVA_HOME/bin/java $JAVA_OPTIONS -Xmx1024m \ -Dweblogic.management.allowPasswordEcho=true weblogic.Server8 - Start WebLogic and access its web console(sh startWebLogic.sh &); sleep 10; firefox http://localhost:7001/consoleUsually, it takes only 10 seconds to start a domain, and 5 more to deploy the Administration Console (on my laptop). :-)Enjoy!

  • Error 404 when accesing newly created ASP.NET website on IIS 7.0

    - by Wodzu
    I've created an ASP.NET website and published it to a file from visual studio. Then I've copied my folder to the inetpub\wwwrot directory. Next under IIS I've converted this folder to the application. Unfortunately, when I try to acces it like this: http://localhost/myappname I am getting 404 error. I was thinking that maybe IIS is not configured to process aspx files, but under http://localhost/default.aspx there is a working sharepoint website. Have you got any ides where might be the problem?

  • Assigning a script to a keystroke to toggle touchpad

    - by sodiumnitrate
    Since my default sony vaio shortcuts don't completely work in Ubuntu 12.04, I'd like to assign a script to Fn + F1, which toggles the touchpad on and off, so that the cursor would stop moving while I'm typing. Since I use a mouse and rarely need to use the touchpad, I don't want to use "disable touchpad while writing", which doesn't really seem to work anyway. I figured that using a script with the following command (this works, but I have to open up a terminal each time): xinput set-prop 12 "Device Enabled" 0 I have two problems at this point. One is that I don't know how to write this script so that it will toggle it off if it is on, and on if it is off. I know I should use an if statement but I don't know what value I should be checking to see if it is on or off. The second one is that I am having problems creating a new shortcut. I use System Settings - Keyboard - Shortcuts. I tried to add, to custom shortcuts, a new one by clicking the '+' sign. I named it Toggle Touchpad, and added the path to the executable script with the line above, by typing /home/irem/.toggletouchpad I have made it an executable with chmod. The problem is that when I click apply, and then click back on it to define the keystroke, it re-opens the dialogue. I cannot define new keys. (It says disabled on the right column of the entry). I have also tried xbindkeys, which almost constantly crashes. I'd prefer the system settings, if I can set the shortcut. I'd appreciate if anyone can help. Thanks.

  • Using VirtualBox to test drive Windows Blue

    - by Fat Bloke
    Oracle VM VirtualBox is great for trying out the latest and greatest technologies and platforms. So when Microsoft recently announced the Developer Preview for Windows Server 2012 R2 and Windows 8.1,  it was with eager anticipation that FatBloke ran to the TechNet Evaluation Center to download the isos. Once downloaded,  a new VM in VirtualBox Manager was created that used Windows 2012 (64-bit) OS type and all the defaults were selected. And on starting the VM, and pointing to the iso file to install from, the excitement rose as we saw a cool new splashscreen image: But suddenly our hopes are dashed.... It would seem that this platform requires an instruction (CMPXCHG16B) that VirtualBox doesn't offer "out-of-the-box".  Fear not, for the VirtualBox team knew that this day would finally arrive and have prepared an "in case of emergency" switch as follows: Power off the vm; At the command line type:  VBoxManage setextradata [vmname] VBoxInternal/CPUM/CMPXCHG16B 1 Start the VM and install Windows Server 2012 R2 This will be enabled by default in a future release, but geeks can't wait, hence this blog. Enjoy! -FB

  • Code Clone Analysis on Rawr &ndash; Part 1

    - by Dylan Smith
    In this post we’ll take a look at the first result from the Code Clone Analysis, and do some refactoring to eliminate the duplication.  The first result indicated that it found an exact match repeated 14 times across the solution, with 18 lines of duplicated code in each of the 14 blocks.   Net Lines Of Code Deleted: 179     In this case the code in question was a bunch of classes representing the various Bosses.  Every Boss class has a constructor that initializes a whole bunch of properties of that boss, however, for most bosses a lot of these are simply set to 0’s.     Every Boss class inherits from the class MultiDiffBoss, so I simply moved all the initialization of the various properties to the base class constructor, and left it up to the Boss subclasses to only set those that are different than the default values. In this case there are actually 22 Boss subclasses, however, due to some inconsistencies in the code structure Code Clone only identified 14 of them as identical blocks.  Since I was in there refactoring the 14 identified already, it was pretty straightforward to identify the other 8 subclasses that had the same duplicated behavior and refactor those also.   Note: Code Clone Analysis is pretty slow right now.  It takes approx 1 min to build this solution, but it takes 9 mins to run Code Clone Analysis.  Personally, if the results are high quality I’m OK with it taking a long time to run since I don’t expect it’s something I would be running all that often.  However, it would be nice to be able to run it as part of a nightly build, but at this time I don’t believe it’s possible to run outside of Visual Studio due to a dependency on the meta-data available in the VS environment.

  • What router settings to use for wireless home network

    - by Question Overflow
    While looking at the setting of my wireless router, I am bewildered by the array of options available. Despite searching on Wikipedia to try to understand the various acronyms, I am still clueless to decide what is the best setting to use although the default works fine. Rather than calling the internet service provider (ISP) to ask them the correct settings, I hope to learn more about the differences between some of the options listed below, so that I would be able to make a more informed decision from now onwards: PPPoE vs PPPoA LLC vs VC-Mux Bridge vs Routed In addition, I would also like to know the significance of the following MTU VPI VCI And whether or when I should manually specify DNS?

  • How to Integrate Dropbox with Pages, Keynote, and Numbers on iPad

    - by The Geek
    The iWork apps are some of the best apps on the iPad, and each show just how powerful a touchscreen device can be with the most basic of computing functions. In fact, there’s not much to dislike about the iWork apps, except for one thing: importing and exporting files. You can open documents from email attachments, download them from websites, or import them from other apps like Dropbox. Once you’ve opened your file in Pages, Keynote, or Numbers on iPad, though, you can only send it via email, upload it to a WebDAV server or Apple’s iDisk service, or wait to sync it with iTunes on your computer. Most other iOS office apps don’t offer nearly as many features as the iWork apps, but they do offer deep integration with Dropbox which makes it easy to view and edit your documents no matter where you are. Dropbox is the most popular file sync and sharing solution, and makes it absolutely painless to share folders with anyone around the world and keep your computers in sync. That is, computers and applications that integrate with Dropbox. However, you don’t need to give up on using Dropbox with iWork apps on iPad. Today we’re going to look at how you can enable WebDAV compatibility on your Dropbox account to let Pages integrate nearly the whole way with Dropbox. It’s not a perfect solution, but it’s much better than the default setup. So let’s get started Latest Features How-To Geek ETC How to Integrate Dropbox with Pages, Keynote, and Numbers on iPad RGB?

  • Oracle Applications Cloud Release 8 Customization: Your User Interface, Your Text

    - by ultan o'broin
    Introducing the User Interface Text Editor In Oracle Applications Cloud Release 8, there’s an addition to the customization tool set, called the User Interface Text Editor  (UITE). When signed in with an application administrator role, users launch this new editing feature from the Navigator's Tools > Customization > User Interface Text menu option. See how the editor is in there with other customization tools? User Interface Text Editor is launched from the Navigator Customization menu Applications customers need a way to make changes to the text that appears in the UI, without having to initiate an IT project. Business users can now easily change labels on fields, for example. Using a composer and activated sandbox, these users can take advantage of the Oracle Metadata Services (MDS), add a key to a text resource bundle, and then type in their preferred label and its description (as a best practice for further work, I’d recommend always completing that description). Changing a simplified UI field label using Oracle Composer In Release 8, the UITE enables business users to easily change UI text on a much wider basis. As with composers, the UITE requires an activated sandbox where users can make their changes safely, before committing them for others to see. The UITE is used for editing UI text that comes from Oracle ADF resource bundles or from the Message Dictionary (or FND_MESSAGE_% tables, if you’re old enough to remember such things). Functionally, the Message Dictionary is used for the text that appears in business rule-type error, warning or information messages, or as a text source when ADF resource bundles cannot be used. In the UITE, these Message Dictionary texts are referred to as Multi-part Validation Messages.   If the text comes from ADF resource bundles, then it’s categorized as User Interface Text in the UITE. This category refers to the text that appears in embedded help in the UI or in simple error, warning, confirmation, or information messages. The embedded help types used in the application are explained in an Oracle Fusion Applications User Experience (UX) design pattern set. The message types have a UX design pattern set too. Using UITE  The UITE enables users to search and replace text in UI strings using case sensitive options, as well as by type. Users select singular and plural options for text changes, should they apply. Searching and replacing text in the UITE The UITE also provides users with a way to preview and manage changes on an exclusion basis, before committing to the final result. There might, for example, be situations where a phrase or word needs to remain different from how it’s generally used in the application, depending on the context. Previewing replacement text changes. Changes can be excluded where required. Multi-Part Messages The Message Dictionary table architecture has been inherited from Oracle E-Business Suite days. However, there are important differences in the Oracle Applications Cloud version, notably the additional message text components, as explained in the UX Design Patterns. Message Dictionary text has a broad range of uses as indicated, and it can also be reserved for internal application use, for use by PL/SQL and C programs, and so on. Message Dictionary text may even concatenate together at run time, where required. The UITE handles the flexibility of such text architecture by enabling users to drill down on each message and see how it’s constructed in total. That way, users can ensure that any text changes being made are consistent throughout the different message parts. Multi-part (Message Dictionary) message components in the UITE Message Dictionary messages may also use supportability-related numbers, the ones that appear appended to the message text in the application’s UI. However, should you have the requirement to remove these numbers from users' view, the UITE is not the tool for the job. Instead, see my blog about using the Manage Messages UI.

  • How Can I Edit Google Chrome's 'History Provider Cache' File?

    - by dissolved
    I'm interested in editing (not completely deleting) contents of some of Google Chrome's cache files. In particular, the 'History Provider Cache' (found in ~/Library/Application Support/Google/Chrome/Default on Mac). As this other question suggests, it appears to simply be a SQLite file. Unfortunately, when I try to open it using a SQLite browser (MesaSQLite) I'm asked for an encryption key. So, I'd welcome any suggestions on how to either (1) determine the encryption key, or (2) an alternate way to edit this file. The end goal is to be able to remove specific annoying suggestions in the Omnibar. I've read countless other techniques, but none seem to remove suggestions that have the clock icon next to it. Some say deleting this file entirely will do the trick (and I imagine it will), but I don't wish to trash my entire browsing history. I find most of the suggestions to be useful and helpful, and I'd like to preserve that.

  • How do you create virtual folders from saved search

    - by Jérôme Radix
    I would like to have on unix-like platforms, the same functionality as to Windows 7 Library folders (aka virtual folders) you see in Windows Explorer. Gnome Nautilus do that kind of virtual folders through saved search. But I want a system-wide solution, not a gnome-wide solution. Is there a tool that creates virtual folders from the concatenation of multiple search queries (the result of multiple find commands ?). The solution should index files for better performances and you should be able to define the default folder for copy operations. I assume the solution of this kind of problem certainly use FUSE, but I can't see a complete solution to this kind of task in FUSE applications.

  • filtering dates in a data view webpart when using webservices datasource

    - by Patrick Olurotimi Ige
    I was working on a data view web part recently and i had  to filter the data based on dates.Since the data source was web services i couldn't use  the Offset which i blogged about earlier.When using web services to pull data in sharepoint designer you would have to use xpath.So for example this is the soap that populates the rows<xsl:variable name="Rows" select="/soap:Envelope/soap:Body/ddw1:GetListItemsResponse/ddw1:GetListItemsResult/ddw1:listitems/rs:data/z:row/>But you would need to add some predicate [] and filter the date nodes.So you can do something like this (marked in red)<xsl:variable name="Rows" select="/soap:Envelope/soap:Body/ddw1:GetListItemsResponse/ddw1:GetListItemsResult/ddw1:listitems/rs:data/z:row[ddwrt:FormatDateTime(string(@ows_Created),1033,'yyyyMMdd') &gt;= ddwrt:FormatDateTime(string(substring-after($fd,'#')),1033,'yyyyMMdd')]"/>For the filtering to work you need to have the date formatted  above as yyyyMMdd.One more thing you must have noticed is the $fd variable.This variable is created by me creating a calculated column in the list so something like this [Created]-2So basically that the xpath is doing is get me data only when the Created date  is greater than or equal to the Created date -2 which is 2 date less than the created date.Also not that when using web services in sharepoint designer and try to use the default filtering you won't get to see greater tha or less than in the option list comparison.:(Hope this helps.

  • What's hot in Oracle Premier Support News for Solaris, Storage and Systems - How to Patch!

    - by user12244613
    Struggling with locating patches for Sun products? Can't find your Oracle System Drivers? This question has been raised many times by customers and was the source of a short video in the Oracle System Support Newsletter in February 2012. The transition between SunSolve and My Oracle Support is to change how you think about the type of patch your looking for. For example, in SunSolve you might have typed e1000g if looking for an Enternet Driver.. but entering e1000g will not find anything in My Oracle Support - Patches and Update Menu. As you need to use the Product (Advanced) search which is driven of the Product Name, therefore you need to type "Ethernet" and select the ethernet product you are looking for to locate the patches for this product. Just to recap that video: If you are looking for the e1000g Ethernet Driver - You need to use Advance Search and search for Enternet 1. Log into My Oracle Support - Select Patches and Updates - Select Product or Family (Advanced Search). 2. In the product line enter: Ethernet and select the product name from the menu. 3. Check remove supersede patches - that ensure you only get relevant current patches in the results. 4. Select Search and the results are displayed. Now you have more options to include the platform (Solaris,Linux etc.) if want to further narrow the search. Need more information? Log into My Oracle Support and what a short 90sec video I put together. View the 7 minute Video using Firefox/chrome – It shows searching for individual patches, Solaris, Firmware etc. If you are not receiving the Oracle System Support Newsletter: Option (a) Within My Oracle Support, make document id: 1363390.1 a favourite and revisit it on the 2nd of each month for the latest content. Option (b) By default the Newsletter  is sent to all customers who have logged a Service Request on an Oracle Systems Hardware Product during the last 12months, unless you have opted out to receiving Oracle Communications on your profile on http://oracle.com

  • Font size of emacs in ubuntu

    - by Ispinfx
    I use emacs in ubuntu and I use Monaco 10 as its default font. However, the font rendering seems a bit odd compared to my gnome terminal with the same font size: It's a bit smaller and not as clear as that in the terminal. I've tried to avoid simply this with size 11 but it's too large for me. How can I make it the same as its look in the terminal ? Any help is appreciated :) UPDATE: I should tell you the above on is GUI emacs running a shell, and the below is the gnome terminal. On the right are their correspond font settings. Both 100% capture with font size 10: (left: emacs, middle: terminal, right: gedit) One more (gvim's):

  • How can I persist certificates in Java's cacerts?

    - by Alan Spark
    We need to have a certificate in Java's cacerts keystore for one of our servers that is authenticated by LDAP. We are using Ubuntu server. We have successfully done this by updating the cacerts file in /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/security but occasionally a Java update is installed and the cacerts file seems to be getting replaced by a default one that doesn't contain our changes. This doesn't happen very often but it is becoming a bit of a pain when it does happen. Is there a better way of adding things to cacerts so that they don't get lost when a Java update happens? Thanks, Alan

  • Modular Architecture for Processing Pipeline

    I am trying to design the architecture of a system that I will be implementing in C++, and I was wondering if people could think of a good approach, or critique the approach that I have designed so far. First of all, the general problem is an image processing pipeline. It contains several stages, and the goal is to design a highly modular solution, so that any of the stages can be easily swapped out and replaced with a piece of custom code (so that the user can have a speed increase if s/he knows that a certain stage is constrained in a certain way in his or her problem). The current thinking is something like this: struct output; /*Contains the output values from the pipeline.*/ class input_routines{ public: virtual foo stage1(...){...} virtual bar stage2(...){...} virtual qux stage3(...){...} ... } output pipeline(input_routines stages); This would allow people to subclass input_routines and override whichever stage they wanted. That said, I've worked in systems like this before, and I find the subclassing and the default stuff tends to get messy, and can be difficult to use, so I'm not giddy about writing one myself. I was also thinking about a more STLish approach, where the different stages (there are 6 or 7) would be defaulted template parameters. Can anyone offer a critique of the pattern above, thoughts on the template approach, or any other architecture that comes to mind?

  • Use ImageMagick to convert TIFF to PNGs, how to improve the speed?

    - by Woo
    I am using "convert" from IM to get PNGs from multi-page TIFF files, everything is good except the speed. From "convert" documentation, I found: For the MNG and PNG image formats, the quality value sets the zlib compression level (quality / 10) and filter-type (quality % 10). For compression level 0, the Huffman-only strategy is used, which is fastest but not necessarily the worst compression. The default PNG compression is 75. So I tried "-quality 0", but almost no changes with the spreed. Anyone can share the ideas of how to improve the spreed? Here are my command: convert 100Pages.tif[0,1,2,3,4,5] -quality 0 100Pages.png Thanks!

  • team foundation server 2010 installation from DVD - I get agent installation instead!

    - by Avi
    GRRRRRRRRRRRR!(#Y%)@#!! They bragged they now have a very easy installation! I don't get it. I entered the MSDN "Disk 5000: Developer Tools" DVD, opened default.htm, clicked on the "Visual Studio Team Foundation Server 2010" link. The VSTFS2010 folder open. I click autorun.exe. And then I get "Microsoft Visual Studio Agents 2010 Setup". I don't get it. Why "agents"? I wanted to instal a server!

  • Tomcat 5.5 - second application returs 404

    - by Tomas Tintera
    There are two versions of web application. Want to have both on one machine so I can test upgrade. If there is one of them copied to Tomcat's webapplications directory and then Tomcat is started, it works fine. So if there is only have only ...webapplicatios\ROOT\... ...webapplicatios\myApp25\... it works fine. Or when there is only ...\webapps\ROOT\... ...\webapps\myApp26\... it works fine too. If I upload both ...\webapps\ROOT and ...\webapps\myApp25 ...\webapps\myApp26 only one of the apps will work. The other one returns 404, page not found. It's running on Windows7 and I use Tomcat 5.5. Tomcat is just default installation. Any idea what to check? How to make both running both apps? Thank you in advance for any help. I'm beginner regarding TC.

  • How to create a new text file in DOS with the end result allowing me to rename the file?

    - by Rolo
    I would like an exact duplicate of the following procedure on a Windows computer using mouse clicks: Right Click in a directory and choose New and then Text Document. When one does this, the text file is created with a default name of New Text Document AND it is also highlighted so that I can type in my own file name. I would like to do this in DOS. I don't care what file name is originally created. What I want is for the name of the file to automatically be highlighted / able to be renamed, so that I can rename it. How can DOS execute / simulate a rename command / an F2 being pressed on the keyboard to a file that it has just created?
