note IlyaM <p>I'm not sure it is correct syntax. From [IPC::Run] docs:</p> <code> '>pty>' means '&>pty>', not '1>pty>' The pseudo terminal redirects both stdout and stderr unless you specify a file descriptor. If you want to grab stderr separately, do this: start \@cmd, '<pty<', \$in, '>pty>', \$out, '2>', \$err ; </code> <p>So probably your code should look like (untested):</p> <code> use IPC::Run qw(run); my ($out, $err); run ( [ '/usr/sbin/pkgrm', 'VRTSvxvm' ], '>pty>', sub { $out .= $_[0]; print STDOUT $_[0] }, '2>', sub { $err .= $_[0]; print STDERR $_[0] }, ); </code> <p> <font color="grey" size="-2"> --<br> Ilya Martynov, <a href="mailto:ilya@iponweb.net">ilya@iponweb.net</a><br> CTO IPonWEB (UK) Ltd<br> Quality Perl Programming and Unix Support UK managed @ offshore prices - <a href="http://www.iponweb.net">http://www.iponweb.net</a><br> Personal website - <a href="http://martynov.org/">http://martynov.org</a><br> </font> 274875 275086
