Adding characters in the word file

[kontotestowe1813]

Hello

I have a list of words in a file txt, I want, for example, to change all words to lowercase letters, or I want all words to start with "!" or "@" or add digits to them from 1-100. A few years ago I created such files but now I don't remember what program it could be. I used maskprocessor a lot but I don't see that it was possible to insert the entire txt file with words there.

I know rule attack. But I need something to be able to change the letters to lowercase, for example, and a special character before them, and at the same time add randomly selected numbers

you can "stack or combine rules"

rulefile:
l ^! $1

pass:
MyPasswort

output:
!mypassword1
