NAMEbasename — return the last component of a pathname
LIBRARYStandard C Library (libc, -lc)
DESCRIPTIONThe basename() function takes the pathname pointed to by path and returns a pointer to the final component of the pathname, deleting any trailing ‘/’ characters.
If path consists entirely of ‘/’ characters, basename() returns a pointer to the string “/”.
If path is a null pointer or points to an empty string, basename() returns a pointer to the string “.”.
RETURN VALUESThe basename() function returns a pointer to the final component of path.

BUGSIf the length of the result is longer than PATH_MAX bytes (including the terminating nul), the result will be truncated.
The basename() function returns a pointer to static storage that may be overwritten by subsequent calls to basename(). This is not strictly a bug; it is explicitly allowed by IEEE Std 1003.1-2001 (“POSIX.1”).
