in reply to Re^3: chomp question
in thread chomp question

while (<>) { chomp if /^CLI\b/; print; } # or without all those default variables while (my $line = <$FILEHANDLE>) { chomp($line) if $line =~ /^CLI\b/; print $line; }

Probably not exactly what you had in mind, right? In either case you either want to check whether the line starts with "CLI" and chomp() it if it does or remember the last line (or whether it started with CLI) and append the text you read instead of adding a new element into the array.

my @lines; my $last_line_was_CLI = 0; while (<>) { chomp; if ($last_line_was_CLI) { $lines[-1] .= $_; $last_line_was_CLI = 0; } elsif (/^CLI\b/) { $last_line_was_CLI = 1; push @lines, $_; } else { push @lines, $_; } }
