Use
The Single UNIX Specification is: <syntaxhighlight lang="text" class="" style="" inline="1">basename path [suffix]</syntaxhighlight>. The required argument, path, is a file path string. The second argument, which is optional, is text to remove from the end of the last name if it ends with the text.
Examples
The command reports the last part of a path ignoring any trailing slashes.
<syntaxhighlight lang="console"> $ basename /path/to/filename.ext filename.ext
$ basename /path/to/ to </syntaxhighlight>
If the suffix argument is included and matches the end of the last name, then that text is removed from the result.
<syntaxhighlight lang="console"> $ basename /path/to/filename.ext .ext filename
$ basename /path/to/filename.ext xx filename.ext </syntaxhighlight>
