Bash

Bash (Bourne-again Shell) is a command-line shell/programming language by the GNU Project. Its name alludes to its predecessor, the long-deprecated Bourne shell. Bash can be run on most UNIX-like operating systems, including GNU/Linux.

Configuration

Bash can be personalized to be fun, useful, or to look cool. Remember to add a short description of what each entry does, and possibly why it would be useful.

Options

 # Changing directory without typing 'cd'. Typing a '/' at the end solves ambiguity.
 shopt -s autocd

 # Enable globbing hidden/dot files (.filename).
 shopt -s dotglob

 # Enable recursive (**) globbing.
