if /i "%comspec% /c ``%~0` `" equ "%cmdcmdline:"=`%" pause

hmm, doesn't work for me. :-/ Too bad. I like it's apparent simplicity.

after some testing, this does work:

if /i "`%comspec%` /c ``%~0` `" equ "%cmdcmdline:"=`%" cmd /k

The first example output, arranged for easier visual comparison:

"C:\WINDOWS\system32\cmd.exe /c ``T:\ENV.558\setenv-testing.bat` `"
"`C:\WINDOWS\system32\cmd.exe` /C ``T:\ENV.558\setenv-testing.bat` `"

And the working one:

"`C:\WINDOWS\system32\cmd.exe` /c ``T:\ENV.558\setenv-testing.bat` `"
"`C:\WINDOWS\system32\cmd.exe` /C ``T:\ENV.558\setenv-testing.bat` `"

There might be some simplification still possible.

Please do a test on this variant: if /i "%comspec% /c %~0 " equ "%cmdcmdline:"=%"; it strips the quotes completely. This might, though, invite false positives, but it will almost certainly lower false negatives. If it works please let me know, so I can update the original stack overflow accordingly: https://stackoverflow.com/a/61511609/1490584

@heetbeet here's the test:

bat file:

if /i "%comspec% /c %~0 " equ "%cmdcmdline:"=%"

output:

The syntax of the command is incorrect.

C:\temp>if /i "C:\Windows\system32\cmd.exe /c C:\temp\setenv-testing.bat " equ "C:\Windows\system32\cmd.exe /C C:\temp\setenv-testing.bat "

I have ConEmu installed. I'll also try from a vm that doesn't have it.

Thanks, the command is incorrect because the if statement doesn't follow up with a command, e.g. if /i "%comspec% /c %~0 " equ "%cmdcmdline:"=%" echo Passed

But what I gathered from your output:

The syntax of the command is incorrect.

C:\temp>if /i "C:\Windows\system32\cmd.exe /c C:\temp\setenv-testing.bat " equ "C:\Windows\system32\cmd.exe /C C:\temp\setenv-testing.bat "

It seems like the expansion did match successfully, i.e. lhs "C:\Windows\system32\cmd.exe /c C:\temp\setenv-testing.bat " equals rhs "C:\Windows\system32\cmd.exe /C C:\temp\setenv-testing.bat " when using the case insensitive /i flag.
