Synopsis

type [options] commands

The type command, like which, locates an executable file in your shell’s search path:

➜ type cat who
cat is /bin/cat
who is /usr/bin/who

However, type is built into the bash shell, whereas which is a program on disk. The type command reveals this:

➜ type which type
which is /usr/bin/which
type is a shell builtin

as well as the locations of other commands:

➜ type rm if
rm is aliased to `/bin/rm -i'
if is a shell keyword

As a built-in command, type is faster than which; however, it’s available only if your shell is bash.
