# script will ALWAYS remove plex docker container
# then if 5TB is mounted will run latest plex docker image
# sleep 120 : written by S.H. and J.P in 2023
# the distilled command is: docker run -d --name=plex --net=host -e PUID=1000 -e PGID=1000 -e TZ=Europe/London -e VERSION=docker -v /media/$USER/5TBUSB/plex/config:/config -v /media/$USER/5TBUSB/plex/data:/data --restart unless-stopped lscr.io/linuxserver/plex:latest
# restart unless stopped may not be desirable!!!

# docker container ps -a | grep -c "lscr.io/linuxserver/plex:latest" 
# gives count of plexes ruining

# protection: if is running and mount exists it does not run!!

## mod: added /$USER as "needs to exist-folder" so HDDs can be monitored, i.e. Spain got to have a pi folder or both both
