    su -c "echo 3 >'/proc/sys/vm/drop_caches' && swapoff -a && swapon -a && printf '\n%s\n' 'Ram-cache and Swap Cleared'" root

    Is there a password for this after hitting enter ??? if not why does it ask me?

    and could this be applied for the home desktops too ???

    swapoff -a && swapon -a

    When are we going to stop talking about cron, and start talking about systemd timers? It’s time, guys.

    • KPPL says:

      Well, not everybody is in love with systemd.

    • Yoandre Valdes Rodriguez says:

      If you are in love with systemd OK go ahead and use timers but don’t pretend that every body is agree with you.

      • Lucas Ramage says:

        Exactly! I literally went out of my way to comment specifically on this. Why does systemd even need a timer? It’s _supposed_ to be an init system.

    • TW says:

      When are we going to stop talking about systemd and move to openRC? It’s time, guys. Long, long past time in fact.
