Hi all!

A little question, I have an output of a script I run from my perl program using open, I need to grep on this script output. My question is, what is faster, calling the script, as follows:
open(OUTPUT, "$script | grep EXPRESSION |");
my @output = <OUTPUT>;

[download]
or doing:
open(OUTPUT, "$script |");
my @output = <OUTPUT>;
@output = grep { EPRESSION } @output;

[download]
In general my question is what is faster, preforming operations using perl or using system, coz' I know a lot of issues are involved (like system opens a shell, etc.).

Thanks
