in reply to gernerating unique string
You could use some high resolution time -
HTH
or if you've got time on your hands -use Time::HiRes qw(gettimeofday); $id = gettimeofday();
Although you'll may have to download them from CPAN (here's Digest::MD5 and Time::HiRes)use Digest::MD5 qw(md5_hex); use Time::HiRes qw(gettimeofday); $id = md5_hex(gettimeofday());
HTH
