Run as root on Linux

Written by masteryeti on January 7, 2022.

Run a script or application as root (privileged). This is a neat way to do it, including a graphical user interface depending on which desktop environment is installed, and whether a DISPLAY is available or not.


if [ "$(whoami)" != "root" ]
then
    if [ -n "$DISPLAY" ]
    then
        command -v gksu >/dev/null 2>/dev/null && exec gksu "$0" "$@"
        command -v kdesu >/dev/null 2>/dev/null && exec kdesu "$0" "$@"
        command -v sux >/dev/null 2>/dev/null && exec sux "$0" "$@"
    fi
    exec sudo "$0" "$@"
fi
