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.
The Single UNIX Specification specification for basename is.
basename string [suffix]
- A pathname
- If specified, basename will also delete the suffix.
basename will retrieve the last name from a pathname ignoring any trailing slashes
