Re: doing a search and replace on a large file

in reply to doing a search and replace on a large file

Any ideas about how I might do this?

Here's one way...

#!/usr/bin/perl -w
use Tie::File;
use strict;

my @ry=();
tie @ry,"Tie::File","mybigfile" or die "mybigfile:$!";
@ry = grep /mypattern/,@ry;
untie @ry;

Please note: that was off the top of my head and untested.
