function purge_local_snapshots() {

    quiet=$(echo ${1,,} | grep "\-q")
    snapshots=$(tmutil listlocalsnapshotdates | grep "-")
    if [[ "${#snapshots}" -eq "0" ]]; then
        [[ "${#quiet}" -eq "0" ]] && echo "No snapshots available!"; return;
    else
        i=1
        ns1=$(date +"%N")
        for d in $snapshots; do
            ns2=$(date +"%N")
            sudo tmutil deletelocalsnapshots $d && { [[ "${#quiet}" = "0" ]] && echo "#$i. $d ($(($ns2-$ns1)) nsec)"; }
            i=$(($i+1))
        done
    fi
