eghdam,

Why make it so complicated ( however it is your script :-)

############# UNTESTED ################ use strict; my $pvid = ''; # initialize my @output = `command`; # Output looks like 7 lines and on [one] li +ne is the pvid: # pvid 00c1be9a467335ce0000000000000000 # I use qx/command/; # easier to see in cod +e for me! foreach my $line ( @output ) { # print "$line\n"; ## If not working, use print to figure out w +hat's happening if ( substr( $line, 0, 5 ) eq 'pvid ' ) { $pvid = substr( $line, 6, 16 ) # or '32' as you require last; } } if ( $pvid eq '' ) { ... } ## Generate warning or do some error h +andling!

I'm coding to my style, but you are free to chose what works for you. But remember if you have to go back to the code and update, make it as easy to understand as possible. Don't spend 2 hours figuring out what you did and then make a 2 line update.

Good Luck...Ed
