I copied it here for easier access.

Forget about complicated scripts for this.

rename is a very old and never properly completed command. If you do not use it properly, the result might surprise you.

For example to remove a prefix abcd from abcd1.txt, abcd2.txt, abcd3.txt etc. in order to get 1.txt, 2.txt, 3.txt simply use

rename "abcd*.txt" "////*.txt"

You need the same number of / as the number of initial characters you would like to remove.

Do place double quotes for both arguments.
