The type command was a shell builtin for Bourne shell that was introduced in AT&T's System V Release 2 (SVR2) in 1984,[1] and continues to be included in many other POSIX-compatible shells such as Bash. However, type is not part of the POSIX standard. With a POSIX shell, similar behavior is retrieved with
command -V name
In the KornShell, the command whence provides similar functionality.[2]
The command is available as a separate package for Microsoft Windows as part of the UnxUtils collection of native Win32 ports of common GNU Unix-like utilities.[3]
whence [...] Korn shell only. Show whether each command is a Unix command, a built-in command, a defined shell function, or an alias.
