The zmbq solution is good, but cannot be used in all situations, such as inside a block of code like a FOR DO(…) loop. An alternative is to use an indicator variable. Initialize it to be undefined, and then define it only if any one of the OR conditions is true. Then use IF DEFINED … Read more
You don’t mention if it has to be batch only, but if you can use ROBOCOPY, try this: ROBOCOPY C:\Source C:\Destination data.zip info.txt /E EDIT: Changed the /S parameter to /E to include empty folders.
var2 is set, but the expansion in the line echo %var2% occurs before the block is executed. At this time var2 is empty. Therefore the delayedExpansion syntax exists, it uses ! instead of % and it is evaluated at execution time, not parse time. Please note that in order to use !, the additional statement … Read more
I think this works: start cmd.exe
You need to check for the parameter being blank: if “%~1″==”” goto blank Once you’ve done that, then do an if/else switch on -b: if “%~1″==”-b” (goto specific) else goto unknown Surrounding the parameters with quotes makes checking for things like blank/empty/missing parameters easier. “~” ensures double quotes are stripped if they were on the … Read more
There is a much better way to handle this issue. Rather than removing Hyper-V altogether, you just make alternate boot to temporarily disable it when you need to use VMWare. As shown here… http://www.hanselman.com/blog/SwitchEasilyBetweenVirtualBoxAndHyperVWithABCDEditBootEntryInWindows81.aspx C:\>bcdedit /copy {current} /d “No Hyper-V” The entry was successfully copied to {ff-23-113-824e-5c5144ea}. C:\>bcdedit /set {ff-23-113-824e-5c5144ea} hypervisorlaunchtype off The operation completed … Read more
You can solve this question with one simple command: echo @dir %* > %systemroot%\system32\ls.bat Make sure you run cmd.exe as admin first if you are on vista and up
You can use: setx PATH “%PATH%;C:\\Something\\bin” However, setx will truncate the stored string to 1024 bytes, potentially corrupting the PATH. /M will change the PATH in HKEY_LOCAL_MACHINE instead of HKEY_CURRENT_USER. In other words, a system variable, instead of the user’s. For example: SETX /M PATH “%PATH%;C:\your path with spaces” You have to keep in mind, … Read more
If you have installed Git for Windows, you should have Git Bash installed, since that comes with Git. Use the split command in Git Bash to split a file: into files of size 500MB each: split myLargeFile.txt -b 500m into files with 10000 lines each: split myLargeFile.txt -l 10000 Tips: If you don’t have Git/Git … Read more
If you run “dir c:\“, the last line will give you the free disk space. Edit: Better solution: “fsutil volume diskfree c:“
