Thanks for your answer, and the next question pops in.

Is there a "rule" when I use perl, awk, sed, grep, cut etc. in a script?
Often I find multiple solutions on the Internet to achieve the same output.

A simple example:

cut -d: -f2
or
awk -F: '{ print $2 }'

Is the one better as the other (CPU/RAM usage), or is it just "taste"
