Re^2: (Windows) verbatim command line arguments inside Perl script

[LanX]

cmd.exe is also allowing unclosed quotes, with is frankly a PITA

D:\tmp\exp>perl -E"say join'|',@ARGV" "1\" 2" "3
1" 2|3

And I already noticed that the escaped quotes are killing my workaround

D:\tmp\exp>type cmd_wrapper.bat
@echo off
echo %*| perl.exe .\wrapped_pl.pl


D:\tmp\exp>cmd_wrapper.bat "1\" 2"
"1\" 2"| perl.exe .\wrapped_pl.pl

what seems to happen is that

1. %* is expanded like a macro before executing the bat
2. The second quote is not considered escaped for echo
3. The pipe is seen as part of an unclosed "string"
4. hence the call to perl.exe is echo'ed like a string and never executed
