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]

alias mv='mv -v'
alias cp='cp -v'
alias rm='rm -v'
alias e='emerge'
alias eu='emerge -uavDN --with-bdeps=y @world'
alias used='cat ~/.bash_history | sort | uniq -c | sort -n'
