file dirname

file dirname name

Returns a name comprised of all of the path components in name excluding the last element. If name is a relative file name and only contains one path element, then returns "." (or ":" on the pre-OSX Macintosh). If name refers to a root directory, then the root directory is returned. For example,

 file dirname c:/

returns c:/.

Note that tilde substitution will only be performed if it is necessary to complete the command. For example,

 file dirname ~/src/foo.c

returns ~/src, whereas

 file dirname ~

returns /home (or something similar).
