NAME
basename, dirname - extract portions of path names
SYNOPSIS
basename string [suffix]
dirname [string ]
DESCRIPTION
basename deletes any prefix ending in
/ and the suffix (if present in string ) from string , and prints the
result on the standard output. If string consists entirely of slash characters, string is set to a single slash
character. If there are any trailing slash characters in string , they are removed. If the suffix operand is
present but not identical to the characters remaining in string , but it is identical to a suffix of the charac-
ters remaining in string , the suffix is removed from string .
basename is normally used inside command
substitution marks (
‘...‘) within shell procedures.
dirname delivers all but the last level of the path name in string .Ifstring does not contain a directory
component,
dirname returns ., indicating the current working directory.
EXTERNAL INFLUENCES
Environment Variables
LC_CTYPE determines the interpretation of string and, in the case of basename, suffix as single and/or
multi-byte characters.
If
LC_CTYPE is not specified in the environment or is set to the empty string, the value of
LANG is used
as a default for each unspecified or empty variable. If
LANG is not specified or is set to the empty string,
a default of "C" (see lang (5)) is used instead of LANG. If any internationalization variable contains an
invalid setting, basename and dirname behave as if all internationalization variables are set to "C".
See environ (5).
International Code Set Support
Single- and multi-byte character code sets are supported.
EXAMPLES
The following shell script, invoked with the argument
/usr/src/cmd/cat.c
, compiles the named file
and moves the output to a file named
cat in the current directory:
cc $1
mv a.out ‘basename $1 .c‘
The following example sets the shell variable NAME to /usr/src/cmd:
NAME=‘dirname /usr/src/cmd/cat.c‘
RETURN VALUE
basename and dirname return one of the following values:
0 Successful completion.
1 Incorrect number of command-line arguments.
