Well, are trying to check the existence of each part of each path
element? So for example, first check /Test exists, then /Test/gary,
then /Test/gary/run and so on? Because just checking the directories in
$PATH is much easier, just read $PATH into an array and iterate over it
and you can use test or [ with -d to see if a directory exists.

For the weird code you have, well, I avoid bash scripting since I prefer
the zsh shell and especially its clearer array syntax. Anyways, for some
reason

[ A="0 ; " ]

is always true. It seems it probably has something to do with expansion,
quoting and the special meaning of ;. Changing the line to

if [ $A = '0 ; ' ]

seems to work.
