A similar command is type. It is shell builtin. Very fast, searches in $PATH
but only executables. e.g
type ls
A comparison with which
$ time which ls
alias ls='ls --color=tty'
/bin/ls
real 0m0.016s
user 0m0.000s
sys 0m0.010s
$ time type ls
ls is aliased to `ls --color=tty'
real 0m0.000s
user 0m0.000s
sys 0m0.000s
