in reply to [OT] Invoking Perl via batchfile: ampersand in PATH [Solved]

So, is there an equivalent of quotemeta for Windows batch files? Or another workaround?

make a hard link with a shorter name without spaces and amperstands

or do the best and most closest approximation of quotemeta, see this.bat, this2.bat ... & is particularly stupid but doable

this3.bat 

@setlocal
@set "thisfile=%~f0"
@echo "%thisfile%"
@set "thisfile=%thisfile:^=\^%"
@set "thisfile=%thisfile:>=^>%"
@set "thisfile=%thisfile:<=^<%"
@set "thisfile=%thisfile:&=^&%"
@set "thisfile=%thisfile:|=^|%"
@set "thisfile=%thisfile:)=^)%"
@set "thisfile=%thisfile:(=^(%"
@set "thisfile=%thisfile:[=^[%"
@set "thisfile=%thisfile:]=^]%"
@set "thisfile=%thisfile:"=\"%"
@echo escaped-thisfile "%thisfile%"
@echo;
@endlocal

Its triple interpolation, or eval interpolation , or ... whatever, its batguano :P

See also the following, maybe improve to make hard links for &nonsense vienv - Edit local environment variables on Win32, CleanPath , SetEnviron.bat

    Thanks! Not sure if it’s what you had in mind, but your advice:

    make a hard link with a shorter name without spaces and amperstands

    gave me the clue I needed: I replaced the directory name with its DOS short name (8.3 format) obtained via dir /x. This is a better solution, as it means I only have to make a single change to the environment variable definition, instead of updating a separate batch file for each Strawberry Perl portable edition.

    Thanks again,
