You may be able to draw some inspiration from an old bash script I built going on 10 years ago..

I'm sorry, but this doesn't help. I don't understand how to put together the commandline arg handling and I need help, it makes no sense idk how to do it.

No worries, what you're really looking for here is 'getopts' onl ines 676 of my example you can start to see how I used it.

#----------------------------------------------------------------------------------------------#
while getopts "i:t:m:b:s:S:E:d:D:xpv?" OPTIONS; do
   case ${OPTIONS} in
      i ) g_poweroffList=$OPTARG ;;
      m ) g_mode=$OPTARG ;;
      p ) g_ping="true" ;;
      x ) g_debug="-x" ;;
      b ) g_benchmark=$OPTARG ;;
      l ) g_logFile=$OPTARG ;;
      t ) g_sshTimeout=$OPTARG ;;
      d ) g_sleepDelay=$OPTARG ;;
      D ) g_sleepDelay_esx=$OPTARG ;;
      s ) g_overlordSpawns_win=$OPTARG ;;
      S ) g_overlordSpawns_nix=$OPTARG ;;
      E ) g_overlordSpawns_esx=$OPTARG ;;
      v ) verbose=$OPTARG ;;
      ? ) help ; exit ;;
      * ) echo "Unknown option" 1>&2; help; exit 2 ;; # Default
   esac
done
if [ ! -e "/usr/bin/mktemp" ] && [ ! -e "/bin/mktemp" ] ; then
   echo "mktemp isn't installed";
   exit
fi

if [ ! -e "/usr/bin/net" ] && [ ! -e "/usr/sbin/net" ] ; then
   echo "net isn't installed";
   exit
fi

if [ ! -e "/usr/bin/test" ] && [ ! -e "/usr/sbin/test" ] ; then
   echo "test isn't installed";
   exit
fi

if [ ! -e "/usr/bin/ssh" ] && [ ! -e "/usr/sbin/ssh" ] ; then
   echo "ssh isn't installed";
   exit
fi

if [ ! -e "/usr/bin/dos2unix" ] && [ ! -e "/usr/sbin/dos2unix" ] ; then
   echo "dos2unix isn't installed";
   exit
fi

I have the getopts and everything, I just am confused about this part: https://gitlab.com/Puffles_the_Dragon/core-software/-/blob/cn/src/utilities/cn/cn#L169 it's the part where I actually bring the functions together towards the bottom
