That only strips one trailing slash. If you want to strip multiple
trailing slashes, then you have to go with something more complex; but
the above if/shopt/else/loop approach is overkill, compared to this
one-liner:
$ foo=/a/b///
$ echo ${foo%%/}
/a/b//
$ echo ${foo%${foo##*[^/]}}
/a/b
Be aware that both approaches will misbehave if HOME is a root directory
(/ or //), where you _don't_ want to strip trailing slashes. So you
really want:
case $HOME in
*[^/]* ) HOME=${HOME%${HOME##*[^/]}} ;;
