basename is a standard computer program on Unix and Unix-like operating systems. When basename is given a pathname, it will delete any prefix up to the last slash (
'/') character and return the result. basename is described in the Single UNIX Specification and is primarily used in shell scripts.
basename was introduced in X/Open Portability Guidelines issue 2 of 1987. It was inherited into the first version of POSIX and the Single Unix Specification. It first appeared in 4.4BSD.
The version of
basename bundled in GNU coreutils was written by David MacKenzie.
The command is available as a separate package for Microsoft Windows as part of the GnuWin32 project and the UnxUtils collection of native Win32 ports of common GNU Unix-like utilities.
The Single UNIX Specification specification for basename is.
