NAMEbasename, dirname — extract portions of path names DESCRIPTIONbasename 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 characters 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. If string does not contain a directory component, dirname returns ., indicating the current working directory. EXTERNAL INFLUENCESEnvironment VariablesLC_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). EXAMPLESThe 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` |
