This might not be the best way, but you could pipe it into a different shell. `#!/usr/bin/perl -w use strict; open BASH, "\|/bin/bash"; print BASH "tar -cf - $_ \| (cd $new_disk; tar -xBpf -)"; close BASH;` [download]	[reply] [d/l]

You could try making the command: `ksh -c "tar -cf - $_ \| (cd $new_disk; tar -xBpf -)"` [download] most shells will take '-c' and use whatever is in the arg as the command they should execute. the shell will lauch, execute what's in '-c' and exit. try "man ksh" or whatever shell you'd like to use to be sure it takes the '-c' arg. 10 to 1 some other monk can give you a better perl solution :) but this answers the question ;) -- I'm a solipsist, and so is everyone else.

Have you looked at Archive::Tar? Also for problems like this it can be very nice to open on pipes and hook them up within Perl.	[reply]

That line looks perfectly fine as a shell command. Perhaps `$_` ends in a newline, or `$new_disk` is not in the format that you expect. Try changing the `system` operator to a simple print to ensure that the command line you are handing the shell is what you think it is. -- Randal L. Schwartz, Perl hacker	[reply]

This also looks like something that might be run in a cron. If so you may want to check environment and path as well.	[reply]
