[pve-devel] perl pipe problems

"
As far as I know, you can't specify the shell to use. Perl uses the
Bourne shell (sh). To use another shell, write a shell script that
calls the script you want to run under ksh. Then call this new script
from your Perl program. Pass arguments as needed.

"IIRC you can only do this at build-time in Unix. (On Win32 there's a
registry entry)."

Seems perl use /bin/sh (instead of /bin/bash), although I set $ENV{SHELL}="/bin/bash"; 

how can is set the default shell in perl?
