NAME
basename, dirname
— return filename or directory
portion of pathname
SYNOPSIS
basename |
string [suffix] |
basename |
[-a] [-s
suffix] string
[...] |
dirname |
string [...] |
DESCRIPTION
Thebasename 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.
EXIT STATUS
The basename and
dirname utilities exit 0 on success,
and >0 if an error occurs.
EXAMPLES
basename together with
-a interprets the second argument as a
string and produces "foo" followed by
"bar" for:
basename -a /usr/bin/foo
/sbin/barPassing multiple arguments to dirname
produces /usr/bin followed by
/sbin
dirname /usr/bin/foo
/sbin/barThe following line sets the shell variable
FOO to /usr/bin.
FOO=`dirname
/usr/bin/trail`SEE ALSO
STANDARDS
The basename and
dirname utilities are expected to be
IEEE Std 1003.2 (“POSIX.2”)
compatible.
