Nano

The nano text editor is a clone and free software alternative to the  Pico editor and is covered under the GNU GPL. (Pico is distributed under a very restrictive licence). Besides basic emulation, nano also has the following other features:


 * GNU autoconf support.
 * Goto line and replace functions (without needing command-line flags).
 * Interactive replace function and spell checker.
 * Auto-indent support.
 * Slang curses-wrapper support.
 * Variable displayed tab width.
 * Regular expression search and replace.
 * Toggles for command-line flags from within the editor.

By default nano has something called hard word wrap. This means that when a line doesn't fit in the window, nano will insert a hard break. When editing configuration files this can be very harmful since breaking a line in to two lines can break the whole configuration. To disable this feature start nano with the -w switch:

nano -w [yourfile]

(using [ ] means that what is inside can optionally be omitted)

installing
First you must install nano by doing this in a terminal Nano is then installed.
