Another way to speed things up is to pre-filter t
ref=eval "sub { $eval }";
die "can't eval: $@" if $@;

Subject: Searching for a word in a file ... need a fas
Hi all,
I'm searching for a word in a file. I wrote the code like this.
while ( ) {
if ( /search_pattern/ ) {
executebale.
}
}
or
Can I use like,
@list = ;
grep();# using grep on list
Let me know a faster way to search.
