Hello Monks,

I have 26 cisco switch dumps. These are large files with close to a million files each. I tried opening individual files and reading them. But it is extremely slow. Ended up using Unix grep instead, which is fast.

Here is my code.

 my $hba_alias = `grep $host_hi $switchdir/*.swc|grep ":  device-alias"|head -1`;`

At some places I am grepping individual files like this

 my $hba_swport = `grep $hba_wwn $switchdir/$switchfqdn|grep "^fc"|head -1`

I want to grep without opening the files which is lot faster and also I can get away from using unix commands. Any ideas how can I accomplish this ?

TIA
