Question

I don’t know anything about regex,but I need to tranform a variable ($name) to uppercase.
Does anybody know how to do it ?

Also, what is a good website for learning regex?

Answer 1

You can try

s/(\pL+)/\U$1/g

The capture parens will find letters, and the \U escape sequence will apply the uc function to the captured text in $1. The /g modifier will repeat the match throughout the string.

For a more generic regex you can try

s/(.*)/\U\1/g

…where it matches all characters, and \1 is the old style capture sequence.
