====== Cleaning ======
Developpers took years to develop a very NOT usefull feature: copy/paste with formatting ( by default !)
To clean script where outputs is "hallucinating" like:
<code>
# ./script.sh
./script.sh: line 1: !#/bin/bash: No such file or directory</code>

===== Solution =====
<code bash> sed -i '1s/^.*#//;s/\r$//' script.sh</code>
