more powerful grep – ack

2010-05-26 2 min read Bash Fedora

For last couple of days, I have been using ack instead of grep. Here is description of ack:

Ack is designed as a replacement for grep.

There are couple of reasons I am using ack. First and foremost being it does not require a filename. So, for seaching amit in all files recursively under the current directory I can simply use

ack amit

More reasons to use ack:

It supports pager option and there can be a rc file that can be used to define the default options that needs to be used with ack. Here is the contents of my $HOME/.ackrc file.

sudo yum install gnome-disk-manager

The interface is very clean and easy to understand and is it very very fast when compared to the other Graphical utilities.

Here are some screenshots to take you through.
