One way to do it would be to break it down into nested loops. I am
not sure you could do it in bash - I am not sure how bash handles
loops. You can try something like: (Not tested)
for a in {A..Z}; \
do for b in {A..Z}; \
do for c in {A..Z}; \
do for d in {A..Z}; \
do for e in {A..Z}; \
do for f in {A..Z}; \
echo $a$b$c$d$e$f ; \
done ; done ; done ; done ; done ; done ; done ; done
