dirname, save cut portion to variable, clean up

Hi guys, last cry for help for today. I appreciate the help so far.

ok so I have a program that dumps a path into my script as a variable ($1)
This path is an example
/home/xbmc/sab_downloads/video/tv/grey's anatomy/season 3

So in order to search thetvdb.com for a show, I need to extract the show name to pass to the other portions you guys have been helping me with so far today. The show name in the path will always be correct and there may often be spaces. I know I can truncate the last dir from the path using dirname but in this case I need to keep the show name.

the beginning of the path:
/home/xbmc/sab_downloads/video/tv

will always be the same with no exceptions however there may not always be anything trailing the name of the show, for example:
/home/xbmc/sab_downloads/video/tv/example

How can I truncate the name of the show in this environment and save it to a variable?

Thanks in advance!

shtool-path

SHTOOL-PATH.TMP(1)					      GNU Portable Shell Tool						SHTOOL-PATH.TMP(1)

NAME

       shtool-path - GNU shtool command dealing with shell path variables

SYNOPSIS

       shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...]

DESCRIPTION

       This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments.  It
       prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found.

OPTIONS

       The following command line options are available.

       -s, --suppress
	   Supress output. Useful to only test whether a program exists with the help of the return code.

       -r, --reverse
	   Transform a forward path to a subdirectory into a reverse path.

       -d, --dirname
	   Output the directory name of str.

       -b, --basename
	   Output the base name of str.

       -m, --magic
	   Enable advanced magic search for ""perl"" and ""cpp"".

       -p, --path path
	   Search in path. Default is to search in $PATH.

EXAMPLE

	#   shell script
	awk=`shtool path -p "${PATH}:." gawk nawk awk`
	perl=`shtool path -m perl`
	cpp=`shtool path -m cpp`
	revpath=`shtool path -r path/to/subdir`

HISTORY

       The GNU shtool path command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken
       over into GNU shtool.
