Perl is supposed to make easy things easy and in place file editing should be easy shouldn't it? Consider:

use strict;
use warnings;

my $cell_name = 'xyzzy';
my $match = 'STARTING_PATTERN';
@ARGV = 'delme.txt';
$^I   = '.bak';

while (<>) {
    s/$1/$cell_name/ if /$match\s+(.*)/;
    print;
}

Yup, that looks easy.

Perl is the programming world's equivalent of English
