Thanks for that Stephen. Having looked at the freedesktop spec that's
useful and I am rather lost at that level. However I am stuck with
BASH. I need help at times and it's always BASH. However I have seen
some info on changing shells on the fly and going back to the default
again. :-) That still looks pretty cryptic in places to me though.
However if needs must. I'd prefer something for all xdg* in etc.
Haven't a clue what the in would be.

John,
BASH is a superset of POSIX. pretty much anything that's POSIX shell
works in BASH. I try to use the more restrictive POSIX set for
compatibility and only use BASH extended features if it would be too
painful to use POSIX only. (e.g. process substitution is just SOOOOO
convenient)
So, just stick that snippet in a file (e.g. "xdg-vals") add "#!/bin/sh"
or even "#!/bin/bash" to the top, make it executable (chmod 700
xdg-vals) and run it with ./xdg-vals.
so, for example:
#!/bin/bash
echo "[XDG Environment]"
while read var default; do
printf "%24s = %s\n" "${var}" "$(eval echo \${$var-${default}\(\*\)})"
done<<"EOF"
