Bash

The Bourne Again Shell (located in /bin/bash) is the default shell of the Linux operating system and is the shell that users of that system will likely be most familiar with.

See bash's man page for more info.

Note: Bash is not available by default in the base system, but can easily be installed from ports if desired.

Other shells that you can install and customize for ease of use are the bash, tcsh, psh, ksh, zsh.
