Delete old files until the disk usage target is reached. The objective is to keep the disk filled to a maximum value, while leaving some free space. The script was made to manage webcam images, and it always keep "snapshots", which are kept for very long time-lapses, and moved off the disk by an other script.
#!/bin/bash
function used_percent {
df -m "$MOTION_PATH" | tail -n 1 | sed -e 's/.* \(.*\)% .*/\1/'
}
function log {
echo "[$(date +%c)] $@"
}
MOTION_PATH="$1"
USED_PERCENT_TARGET=${USED_PERCENT_TARGET:-90}

$scope.toggleActive = function(user) {
Restangular.one('users', user.UserId).all('active').post({
