grep is a command-line utility for searching plain-text data sets for lines that
match a regular expression. Its name comes from the ed command g/re/p (globally
search for a regular expression and print matching lines), which has the same
effect. grep was originally developed for the Unix operating system, but later
available for all Unix-like systems and some others such as OS-9. [0]

[002] Setup
________________________________________________________________________________

To use GNU grep as the system grep, the alternatives system must be used. The
GNU grep implementation is very fast [1] and is recommended over the default
provided by busybox.

|  $ kiss a gnugrep /usr/bin/grep                                              |
|  $ kiss a gnugrep /usr/bin/egrep                                             |
|  $ kiss a gnugrep /usr/bin/fgrep                                             |
|                                                                              |

To undo these changes run 'kiss a', find the relevant output and run the
corresponding commands. Each line of output from 'kiss a' is a valid command
to give back to 'kiss a'.
