History
The type
command was a shell builtin for Bourne shell that was introduced in AT&T's System V Release 2 in 1984, 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 Korn shell, the command whence
provides similar functionality.
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.
