Assign UID from a specific range via bash script - RHEL7

Hi all,

Hoping someone can help or point me in the right direction :)

I am looking to create a bash script to create local users using the useradd' command, however I need the accounts to be given a UID only from a certain range, so let's say 1000-2000 and the UID also needs to be assigned backwards and counting down, so..

2000
1999
1998
etc..

Does anyone know a how I can achieve this?

I am running RHEL 7

Any help will be appreciated :)
