Hello,

An oft-repeated means for seeding bash $RANDOM is:
RANDOM=$$$(date +%s)

However on Linux 2.6.18-xen #1 SMP Fri May 18 16:11:33 BST 2007 i686
GNU/Linux thise method is not working for me:
RANDOM=$$$(date +%s)
echo $RANDOM

I keep getting a value of 15929. Why is the seed value invalid? 32-bit
OS?

Thanks



RANDOM is a special var.

Try:
unset RANDOM
RANDOM=$(date +%s)

You should have tried it yourself.

unsetting RANDOM takes away its "specialness".

Is not this exactly what the OP wants?
