I am trying to create a script that opens a new tmux session, then changes user and runs a script inside that tmux session.
The purpose of this is to create a new tmux session for a game server, which has a different unix user assigned to it. I have heard that giving servers their own users was good practice, but I would still like to have a script in the home directory of my main user to start the server for convenience. I would like the tmux session to be available from my main user, yet be logged in to the game server user.
The main problem is that there is a password prompt that I cannot get around, requiring me to attach to the tmux session, enter the password, and then detach.
This is what I have tried:
#!/bin/sh
tmux new -d -s Minecraft sudo -u minecraft /home/minecraft/server/start.sh
I have tried every combination of running the script with sudo, adding su - Minecraft to the script, and su Minecraft -c "script", and in each one it either requires me to attach to the tmux session and login or just does not work, leaving no tmux session open.
I am trying to find a solution which would allow me to type in my sudo password or the other user's password when I run the script which invokes tmux, instead of having to login by attaching and then detaching.
Any tips would be appreciated. This is obviously a hobby project and not of vital importance. I am also new to linux and am trying to learn best practices. I am open to being told if I am taking the the wrong approach.

Two approaches:
- Edit
/etc/sudoersto allow your user to dosudo -u minecraft,
or specificallysudo -u minecraft /home/minecraft/server/start.sh,
without a password. - Do
sudo -u minecraft sleep 0in your script before thetmuxcommand.
This will ask you for your password.
Subsequentsudocommands for the next few minutes
will not require a password.
