basename, dirname - deliver portions of path names SYNOPSIS
/usr/bin/basename string [suffix] /usr/xpg4/bin/basename string [suffix] dirname string DESCRIPTION
The basename utility deletes any prefix ending in / and the suffix (if present in string) from string, and prints the result on the stan- dard output. It is normally used inside substitution marks (``) within shell procedures. /usr/bin The suffix is a pattern defined on the expr(1) manual page. /usr/xpg4/bin The suffix is a string with no special significance attached to any of the characters it contains. The dirname utility delivers all but the last level of the path name in string. EXAMPLES
Example 1: Setting environment variables The following example, invoked with the argument /home/sms/personal/mail sets the environment variable NAME to the file named mail and the environment variable MYMAILPATH to the string /home/sms/personal: example% NAME=`basename $HOME/personal/mail` example% MYMAILPATH=`dirname $HOME/personal/mail` Example 2: Compiling a file and moving the output This shell procedure, invoked with the argument /usr/src/bin/cat.c, compiles the named file and moves the output to cat in the current directory: example% cc $1 example% mv a.out `basename $1 .c` ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of basename and dirname: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES, and NLSPATH. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. ATTRIBUTES

dirname, basename - Parse pathname components SYNOPSIS
#include <libgen.h> char *dirname(char *path); char *basename(char *path); DESCRIPTION
The functions dirname and basename break a null-terminated pathname string into directory and filename components. In the usual case, dirname returns the string up to, but not including, the final '/', and basename returns the component following the final '/'. Trailing '/' characters are not counted as part of the pathname. If path does not contain a slash, dirname returns the string "." while basename returns a copy of path. If path is the string "/", then both dirname and basename return the string "/". If path is a NULL pointer or points to an empty string, then both dirname and basename return the string ".". Concatenating the string returned by dirname, a "/", and the string returned by basename yields a complete pathname. Both dirname and basename may modify the contents of path, so if you need to preserve the pathname string, copies should be passed to these functions. Furthermore, dirname and basename may return pointers to statically allocated memory which may be overwritten by subsequent calls. The following list of examples (taken from SUSv2) shows the strings returned by dirname and basename for different paths: path dirname basename "/usr/lib" "/usr" "lib" "/usr/" "/" "usr" "usr" "." "usr" "/" "/" "/" "." "." "." ".." "." ".." EXAMPLE
char *dirc, *basec, *bname, *dname; char *path = "/etc/passwd"; dirc = strdup(path); basec = strdup(path); dname = dirname(dirc); bname = basename(basec); printf("dirname=%s, basename=%s ", dname, bname); free(dirc); free(basec); RETURN VALUE
Both dirname and basename return pointers to null-terminated strings. BUGS
In versions of glibc up to and including 2.2.1, dirname does not correctly handle pathnames with trailing '/' characters, and generates a segmentation violation if given a NULL argument. CONFORMING TO
