Re^2: run in-program shell script under windows using cygwin

I was also surprised ...

Why?

$ perl -V:sh
sh='cmd /x /c';
[download]

Unless your cygwin perl hash something bash in there, cmd.exe is your shell

My *cygwin*alike* has

$ C:\citrusperl\mingw\msys\bin\perl -V:sh
sh='/bin/sh';
[download]

So even if *my*cygwin*alike* has got /bin/sh , it won't work when calling perl from cmd.exe, only from the bash itself ... in actual cygwin that might get resolved (if cygwin perl is linked to cygwin dll) but it depends on the perl being called

So even if mycygwinalike* has got /bin/sh , it won't work when calling perl from cmd.exe* Actually it will, same magic that actual cygwin uses to resolve it is used by the mingw/msys compiled version So check your paths, check your shebangs people :)	[reply]

I was surprised because I did not expect that, simply. Now, running your command, I get this: `$ perl -V:sh sh='/bin/sh';` [download] And I have also this: `$ which sh /usr/bin/sh` [download] Well, there is something that I don't get here...	[reply] [d/l] [select]

Well, there is something that I don't get here... Well, does /bin/sh exist? Don't know why your perl is configured with /bin/sh instead of /usr/bin/sh ... :)	[reply]

Well, /bin/sh and /usr/bin/sh both exist, and the script works (with Perl) with both paths in the shebang line of the shell script.	[reply]

Well, you're running a windows perl under cygwin , cygwin isn't windows , cmd.exe don't do shell scripts without ftype/assoc	[reply]
