in thread How likely is rand() to repeat?

Or run this till the cows come home.

perl -MData::UUID -le 'print Data::UUID->new->create_str'

Or write a sequence generator.

Update: for less predictability in recreating-

perl -MData::UUID -le 'print Data::UUID->new->create_from_name_str("ta +blename?",rand())'
