.bash_alias

altalias [optional: -s] [nickname]=[commands] [nickname2]=[commands2] ...

-s will save these aliases across this and future sessions. Otherwise, altalias has the same behavior as alias.

If desired, altalias can completely replace normal alias, since it extends the behavior of alias without interfering.

# alias alias to altalias
if typeset -f altalias > /dev/null; then
    alias alias='altalias'
