Run a shell script in Terminal through a keyboard/desktop shortcut-CodePudding

I'm using Linux (Mint 20.3) to run a simple Minecraft server and I want to be able to start the server with a keyboard or desktop shortcut. I also want to be able to interact with the server in a terminal after it starts. I'm currently using the server software supplied by Mojang. I wrote a little program to get things started:

#!/bin/bash
cd /home/trevor/Minecraft_Server
LD_LIBRARY_PATH=. ./bedrock_server
exec $SHELL

I can get the server to run but I have no clue how to get it to open a terminal window so I can interact with the server. I'm relatively new to Linux so any input would be greatly appreciated.

CodePudding user response：

you can use screen to detach and attach to run commands into the minecraft terminal.

to install screen: apt-get install -y screen

To launch, update your script with something like: screen -S mcs ./bedrock_server

to reattach, run the following in a terminal: screen -r mcs

CodePudding user response：

Use screen in your script to reattach to bedrock process.

Install screen:

apt-get install screen

Define your script as:

#!/bin/bash
export LD_LIBRARY_PATH=.
cd /home/trevor/Minecraft_Server
screen -d -m -S bedrock ./bedrock_server

After invoke your script, screen creates a socket that can be used to reattach to your script terminal. You can show screen sockets available with:

screen -ls

Parameter -S defined 'bedrock' as the socket name. So you can open another terminal as you like and reattach to the bedrock process with:

screen -r bedrock

If you detach the screen with CTRL C the screen will be closed and so the minecraft bedrock server. To deattach without close the process you must use CTRL A and CTRL D.
