Off-topic for this list, so just a very short remark.

Yes, "pwd" might slow down performance and perhaps only would be useful
if the "-P" option is required , that's why I first mentioned
"basename "$PWD"". I don't know if the "printf" command is faster than
the "basename" command. If I need a fast script, I would chose dash
instead of bash and test if "basename "$PWD"" does the job as fast as
"printf". An external command not necessarily is slower, but of course
using the "PWD" variable most likely is faster than using the "pwd"
command. At least dash is much faster than bash. So assuming bashisms
aren't needed, I prefer dash over bash.
