in reply to Newbie to PERL removing text from array

This mainly depends on the file format. If you can be 100% sure that this, and only this is the way lines will be presented, then you can do the following:

my @output; foreach my $line (@lines) { my @split = split ' ', $line; #split by whitespace pop @split if $split[0] eq '*'; #getting rid of leading * $split[0] =~ s/\.//g #remove the dots from the element push @output, $split[0] . ' ' . $split[3]; }

Otherwise, you'll need to do a foreach on each of @split's elements, match them to a pattern and use those that you need.
