Re: removing lines that are in the end of a file

in reply to removing lines that are in the end of a file

Another approach using split and join:
#!/usr/bin/env perl use strict; use warnings; foreach my $file (grep { -f } @ARGV) { my $data = slurp_file ($file); my $new_data = join ('', (split /(SIL\n)/, $data, 5)[ 0 .. 3 ]); open my $OUT, '>', $file or die $!; print $OUT $new_data; close $OUT; } sub slurp_file { local (*ARGV, $/); @ARGV = shift; <> }

Update

This only works if there are no additional SIL lines interspersed between the first line and the SILL lines at the end.
