Script to generate script, takes care of read permission with sudo

Instead of edit checking afterwards a manual typed script, write a prove script to generate later on scripts.

System change, the script will change while if it can.

Build machine(s) to reproduce machines :)

put it into for example ~/.bashrc will generate a file for afterwards sourc-ing.
