This is the ebuild for bash, the standard shell for Funtoo Linux systems.

Bash is the GNU Project's Bourne Again SHell, a complete implementation of the IEEE POSIX and Open Group shell specification with interactive command line editing, job control on architectures that support it, csh-like features such as history substitution and brace expansion, and a slew of other features. [1]

Learning Bash

The following articles, written originally for IBM developerWorks by Daniel Robbins, serve as an excellent introduction to the bash shell:
