'''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 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).
