Re: deleting lines from file

[phenom]

Not tested, but how about:

#!/usr/bin/perl

use strict;
use warnings;

my $valueToDelete = $ARGV[0] || "two 222 sld";

open(FH, "oldfile") or die "open failed: $!";
my @contents = <FH>;
close(FH);

open(FH, ">oldfile") or die "open failed: $!";
foreach my $line (@contents) {
     print FH $line if($line !~ /$valueToDelete/);
}
close(FH);
