Hi all, this one should be self explaining:

karls-mac-mini:monks karl$ for i in {0..9}; do echo $i; done | perl -p
+e '$_++'
12345678910karls-mac-mini:monks karl$

Ok, but i want a newline:

karls-mac-mini:monks karl$ for i in {0..9}; do echo $i; done | perl -n
+e '$_++; print qq($_\n)'
1
2
3
4
5
6
7
8
9
10

Quite simple. Got it. But sometimes i struggle a little bit with the essentials :-(

So i wonder if there is a TMTOWTDI for doing something like this.

Thank you very much for any hint and best regards, Karl
