basename
, dirname
— return filename or directory portion of
pathname
basename |
string [suffix] |
basename |
[-a ] [-s
suffix] string
[...] |
dirname |
string [...] |
The basename
utility deletes any prefix
ending with the last slash ‘/
’
character present in string (after first stripping
trailing slashes), and a suffix, if given. The
suffix is not stripped if it is identical to the
remaining characters in string. The resulting filename
is written to the standard output. A non-existent suffix is ignored. If
-a
is specified, then every argument is treated as a
string as if basename
were
invoked with just one argument. If -s
is specified,
then the suffix is taken as its argument, and all
other arguments are treated as a string.
The dirname
utility deletes the filename
portion, beginning with the last slash
‘/
’ character to the end of
string (after first stripping trailing slashes), and
writes the result to the standard output.
The basename
and
dirname
utilities exit 0 on success,
and >0 if an error occurs.
The following line sets the shell variable
FOO
to /usr/bin.
FOO=`dirname
/usr/bin/trail`
The basename
and
dirname
utilities are expected to be
IEEE Std 1003.2 (“POSIX.2”)
compatible.
The basename
and
dirname
utilities first appeared in
4.4BSD.
