On some distributions which is an alias itself. That's the case on my
system - Debian based.

$ alias which
alias which='type -path'

The -path restricts type to only print the path for files. Type is a
builtin which it shows:

$ type type
type is a shell builtin

and then:

$ type which
which is aliased to `type -path'
$ type ls
ls is aliased to `ls --color=auto'

and -P forces a PATH search:

$ type -P ls
/bin/ls
