Here is my Katas for creating BASH programs that work. Nothing is new here, but from my experience pepole like to abuse BASH, forget computer science …

du --max-depth=1 2> /dev/null | sort -n -r | head -n20
ou mieux :
du -h --max-depth=1 2> /dev/null | sort -h -r | head -n20

automatically detects problems with sh/bash scripts and commands.

tout est dans le titre ;)
ou par quoi remplacer le bon vieux ipconfig...

echo -e '!\nThat was a bad idea. Don'"'"'t copy code from websites you don'"'"'t trust!
