meanwhile me:
$ cat ./scripts/killGameUsers.sh
#!/bin/sh
# kill all their processes
pkill -9 -u game_minecraft
pkill -9 -u game_steam
pkill -9 -u game_epic
# cleanup their /tmp bullshit
find /tmp -maxdepth 1 -user game_minecraft -exec rm -rf "{}" \;
find /tmp -maxdepth 1 -user game_steam -exec rm -rf "{}" \;
find /tmp -maxdepth 1 -user game_epic -exec rm -rf "{}" \;
missed the important bit:
alias killGames="~/scripts/killGameUsers.sh"
