ack: grep but better!

I came across ack today, and now grep is sleeping outside. It's very much like grep, except it assumes all the little things that you always wanted grep to remember, but that it never did. It actually left the light on for you, and put the toilet seat down.

Anyway, there were some rough bits with installation. On Ubuntu, it is installed by sudo apt-get install ack-grep. If you think, hey, I will take the obvious path and install "ack"! You will be thinking with wrongitude. For ack is, in fact, a Kanji code converter, which I discovered after not a little anger. On RHEL, CentOS, and the like, you have to install with cpan -i App:Ack.

Once installed, just try some ack-grep STRING.

Oh, and don't forget to add ack-grep --thpppt to exit your shell scripts:
