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]

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.

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'.
