问题 I am trying to load a column from a CSV file into a variable. My CSV file contains empty columns so can have ,, which seems to be ignored by the following: FOR /F "tokens=3 delims=," %%a in (csvfile.csv) do ( set date=%%a echo %%a ) So if file csvfile.csv contains fred,wilma,tony, john, greg, wilber, blake chris,,steve,deon,bryan,mark,anthony I would like the result: tony steve But I get: tony deon If I put a white space in the empty column this does work as expected. How do I set delims so

问题 How can you get the directory of the script that was run and use it within the .cmd file? 回答1: Raymond Chen has a few ideas: https://devblogs.microsoft.com/oldnewthing/20050128-00/?p=36573 Quoted here in full because MSDN archives tend to be somewhat unreliable: The easy way is to use the %CD% pseudo-variable. It expands to the current working directory. set OLDDIR=%CD% .. do stuff .. chdir /d %OLDDIR% &rem restore current directory (Of course, directory save/restore could more easily have

问题 I've been wrestling trying to get the syntax right on this batch file and I cannot figure out why some things aren't working. The variable i is not getting incremented each time I do it. Concatenation on strc doesn't seem to concatenate. Here is my code: set i=0 set "strc=concat:" for %%f in (*.mp4) do ( set /a i+=1 set "str=intermediate%i%.ts" set strc="%strc% %str%|" ffmpeg -i "%%f" -c copy -bsf:v h264_mp4toannexb -f mpegts "%str%" ) set strc="%strc:-1%" ffmpeg -i "%strc%" -c copy -bsf:a

问题 I have some lines of text. Then I have a list with test-words. I like to look up each line of the text and check if one of the test-words appears in it. Beforehand this works well with a commands like these: IF not "!stringToTest:%searchstring%=!"=="!stringToTest!" However, now this seems to be more complicated as I have nested Loops? I try to create a little MWE for my problem: @echo off setlocal enabledelayedexpansion set /a counterPC=0 set "listPC=Win10,Motherboard,USB-Port,Core" FOR %%G

问题 I usually get the current working directory by giving the batch command %~dp0 for combine multiple csv files. But I encountered ampersand (&) symbol while getting current working directories which makes batch file broke after the '&' saying the path after & is not recognized as an internal or external command.

问题 I want to remove the Google Chrome pinned icon on the taskbar. The uninstall does NOT remove the icon. I modified code to remove just the Google Chrome.lnk. What I want to do (knowing about VBS) is to loop through all the user folders not just the current user which is I believe defined as strCurrentUserAppData . The other desire I would like to do with this code is to use it with SCCM to do a clean install of Chrome. I installed the x64 version and need to replace it with the x86 version.
