i'm creating a script that adds users to LDAP from a text file containing their name and other information. i want to create unique UID numbers for each user. what would be the best way to do this? the only way i can think is to have a separate file containing the uid number that would be incremented every time a user is added. is there any way i could store this number in my perl script itself? the script is for someone else and i'd like for it to be as self-contained as possible. basically i want to know if i can store a number within my script and actually increment it every time a user is added, so it would basically be changing itself every time.
