[csw-maintainers] Perl scripting question

[Juergen Arndt]

Ok, I got the clou.

The exec function of perl calls according to perldoc "/bin/sh -c ..." on unices. On Solaris /bin/sh is indeed the bourne shell, on linux it's a link to /bin/bash. That's the difference and that's why the code snippet below works different on linux and Solaris. 

Thank you
