Alphanumeric number generator
hey guys, does anyone knows how can i generate an alphanumeric unique number each time i execute my script?
is there any ready script for that?

Check simply the time function. It returns the number of seconds since January 1, 1970.
This guaranteed to be unique each time you run your script (unless you run it several times per second).
$ perl -e "print time"

You could use Data::UUID.
This will generate unique values even when running multiple times a second and guarantees unique values until 3400 AD.
