Name         : ack
Architecture : noarch
Summary      : Grep-like text finder

Description  : Ack is designed as a replacement for grep.

And their websites says -

Designed for programmers with large heterogeneous trees of source code, ack is written in portable Perl 5 and takes advantage of the power of Perl’s regular expressions.

And I completely agree with that. There are really a lot of developer friendly options that ack has. As with any other unix/linux utility you can create a rc file for the defaults of the program and with ack you dont need to do that manually. You can simply run

ack -i --create-ackrc >~/.ackrc

and you will have a ackrc file in your home folder. Now you can open this and modify this to your heart’s content and enjoy the new grep of your life.
