But you should make sure that $RANDOM assumes different values after a
reboot (same for perl's rand(100), which is likely more advanced and
less likely to suffer from that problem).

this can be done by prefixing your 'for' line with:
RANDOM=$(($(date +%s) % 32768))
this seeds the random number generator based on the number of seconds
since 1/1/70, so is likely to avoid repeats.
