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 en utilisant la fonction watch (yum install inotify-tools)

#!/bin/bash #set -x cd /var/lib/nethserver/ftp/espcam mkdir -p archives mv *.jpg 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

avec un test horaire

#!/bin/bash cd /var/lib/nethserver/ftp/espcam mkdir -p archives mv *.jpg archives while true do currenttime=$(date +%H:%M) if [[ "$currenttime" < "21:00" ]] || [[ "$currenttime" < "07:30" ]]; then while watch -g -n 10 -d ls -l *.jpg 2>&1 >/dev/null do cp *.jpg /var/lib/nethserver/vhost/c36066d722884c4/photo.jpg mv *.jpg archives sleep 10 done else sleep 60 fi done exit 0
