How to remove the first 22 characters in a string (Perl)?

Question

Perl

I can't solve a simple problem in Perl, since I've encountered it for the first time. There is a line of text, with numbers, letters and signs. You just need to remove the first 22 characters. This construction doesn't work:
$ps_text =~s/^{22}//g;
UPD:
Construction like $ps_text =~s/^.\{22\}//g; produces a result consisting of 20 digits.
Well, I can understand how to remove the last first 22 characters and the last 1.

Answer 1

Instead of a regexp in a condition.
^.\{22\}

Answer 2

s/^.{22}//
