I didn't give much consideration to what's left of the semicolon.
But echo ${TEST} will always write a newline unless, quote:
-n do not output the trailing newline
-e enable interpretation of backslash escapes
The second of these allows you to spring surprises.
$ Test="abcd"
$ echo -n ${Test}
abcd$ echo ${Test}
abcd
$ Test=""
$ echo ${Test}
$ Test=
$ echo ${Test}
$ unset Test
$ echo ${Test}
$ Test="abcd\c"
$ echo -e ${Test}
abcd$
Cheers,
