Re: Counting devices types, device sizes and number of devices.

I'd use a hash, keyed on raid type and device size. You only need one value then: the count:

$count{$raid_type}{$device_size}++;

$count{$raid_type,$device_size}++;

Hi JavaFan, That's neat. Now I just need to figure out a way to get those values inside the hash. Perlpetually Indebted To PerlMonks	[reply]

Hi Jaimon, Thanks a lot. But thing is, the output given in my post is output of a command.Does Data Dumper have the facility to take in command output? Perlpetually Indebted To PerlMonks	[reply] [d/l]
