I have a file "file1" that contains: dave bob rich jim I have a second file "file2" that contains: dave rich I need "file2" listing to remove lines from "file1" to create a "file3" that contains only: bob jim I tried this code: #!/usr/bin/perl use strict; # use warnings; open(MYOUTFILE, ">file3"); open(MYOUTFILE, ">>file3"); my $file = shift or die "Usage: $0 file1 < file2"; my $file_contents = do { local (@ARGV, $/) = $file; <> }; my $nets = join "|", map {chomp;$_} $file_contents; /$nets/ or print MYOUTFILE while <STDIN>; close(MYOUTFILE); But it does not get me my example of file3 should look like. Help! Thanks.. RCP
