ESPCAM

un code qui fonctionne ( pas de pb de saturation…) pour prendre à intervalle régulier(frequence) une photo jpg et la poser par ftp sur le serveur.\ un script place la photo sur le site web

#!/bin/bash #set -x cd /var/lib/nethserver/ftp/espcam mkdir -p archives while watch -g -n 10 -d ls -l *.jpg 2>&1 >/dev/null do cp *.jpg /var/lib/nethserver/vhost/nom_repertoire/photo.jpg mv *.jpg archives sleep 10 done exit 0
