Even better is to avoid dirname altogether. It's actually not necessary
at all in a POSIX shell; neither is basename.
The above can be rewritten much more efficiently as:
pwd=$(pwd)
: ${tsdir:=$pwd}
: ${bindir:=${pwd%/*}}
Just sayin'... :-)
I'm assuming this script is declared #!/bin/bash at the top, due to all
the bashisms it uses?
