Why do you use 'cat'? First of all it won't work for people who
aren't on UNIX/Linux systems. Secondly it isn't needed.
perl -e 'while (<>) { print if /Error/ }' logfile.log
Perl doesn't have to have input fed to it via STDIN exclusively.
This is like you are approaching your front door with your key in hand
but you call the locksmith to unlock your door for you. You can do
that, but why?
