Strip directory and suffix from filenames
Syntax basename string [suffix] basename [-a] [-s suffix] string [...] dirname string Key -a Treat every argument as a string (as if basename were invoked with just one argument) -s The suffix is taken as its argument, all other arguments are treated as a string.
The basename 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.
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.
basename and dirname will exit 0 on success, and >0 if an error occurs.
