Arrêt / Redémarrage Raspberry

Bonjour,

Je souhaiterais savoir s'il existe une solution pour arrêter proprement le Raspberry et le redémarrer.

Nous avons jusqu'ici débranché électriquement le Raspberry, les cartes SD sont désormais corrompues, ce qui n'est pas étonnant.

J'aimerai donc savoir s'il existait une solution pour arrêter proprement et/ou redémarrer le raspberry, peut-être un bouton poussoir ou quelque chose de ce type pour éviter d'endommager les cartes SD.

Evidemment je connais les commandes suivantes :

sudo halt

sudo shutdown -r now

Mais nous cherchons un moyen de redémarrer le Raspberry sans devoir s'y connecter à distance.

Voila pourquoi je recherche une solution propre qui m'éviterait de devoir reformater sans cesse la SD.

Je vous remercie.

My writing French is not that good. Do you mind if I try to help in English?

So... The "reset" causes a brutal reset, only slightly less brutal than removing the power.

I think that logging in to the console and typing commands is also not what you're looking for. You want a power button like on a PC that causes a shutdown.

I would connect a pushbutton between GND and one of the GPIO ports. Then I'd write a script:
#!/bin/sh
pin=1 # better known as GPIO18, see the pinout documentations for the P1 connector on rasbperry pi.
gpio mode $pin in
gpio mode $pin up # I don't know if this obsoletes the above command, extra is easier than figuring that out.
while [ `gpio read $pin` -eq 1 ] ; do
sleep 0.1
done
halt
call this script say "monpowerbutton" and save it in /usr/local/bin, change the mode to 755 and call it from /etc/rc.local:
/usr/local/bin/monpowerbutton &
That's it! A power button that causes a neat shutdown when pressed.
