Hi!
There is actually slight error in this code.
> $a=~s/\.\d+$//; # <---- this does the trick
This handles only one or more digits (\d stand for digits), so unless the last part of the string is a number this won't work.
Should be something like
$a=~s/\.\w+$//; # (\w stands for word charachters)

I have a line: i.like.donuts.but.only.with.tea
now I want to remove everything that follows the last "." including the last ".".

you can use a regex for that.
=== Documentation (from command line:)
perldoc perlre
=== Code:
use strict; use warnings; my $a="i.like.donuts.but.only.with.tea"; $a=~s/\.\d+$//; # <---- this does the trick print $a, "\n";
# this prints: i.like.donuts.but.only.with.tea
=== explanation: see documentation ;-)
