in reply to using Backtick inside perl gives different output

Another way to do it:

#!/usr/bin/perl use strict; use warnings; open my $cmd, '-|', '/usr/sbin/ntpq', '-p' or die "Cannot open pipe fr +om ntpq because: $!"; while ( <$cmd> ) { my $offset = ( split )[ 8 ]; print "$offset\n" if /^\*/; } close $cmd or warn $! ? "Error closing ntpq pipe: $!" : "Exit status $? from ntpq";
