How to make my init.d script change users
提问by Drexl
I have this script which I would like to switch to the user "terraria" before starting the daemon. I can't figure out how to do it. My research brings me to bash scripts using su my_user -c, but I don't think that works in this case.
我有这个脚本，我想在启动守护程序之前切换到用户“terraria”。我不知道该怎么做。我的研究使我使用 bash 脚本su my_user -c，但我认为在这种情况下不起作用。
