have you tried adding && between them? I used to do that when doing apt-update.

i have tried it but doesn't work

You can't run them all at once, but by adding a single '&' at the end, will put the running command in the background (and will allow the next command to run immediately).

Example:

 

#! /bin/bash
clear
timeout 60s
xterm -e sh -c "cd /home/minecraftserver/Desktop/test-server/BungeeCord; java -Xmx100M -Xms100M -jar BungeeCord.jar" &
xterm -e sh -c "cd /home/minecraftserver/Desktop/test-server/lobby; java -Xmx785M -Xms785M -jar spigot.jar" &
xterm -e sh -c "cd /home/minecraftserver/Desktop/test-server/factions; java -Xmx785M -Xms785M -jar spigot.jar" &
xterm -e sh -c "cd /home/minecraftserver/Desktop/test-server/plots; java -Xmx785M -Xms785M -jar spigot.jar" &

I believe this runs the first command and then if it was successful the next command is run after, so not at the same time

&& would work well for apt-update && apt-upgrade though

As @Tomsen mentioned, you can't run their simultaneously, and you might want to try his solution. Mine would using a programming language that supports forks , like C or C++. This way you could run each command as a different process.

Going from a scripting language to a low-level system language, might be a slight to big of a jump. He only provokes an external application from commandline (from what we can see), so I would think c/c++ would be kind of a waste. The language should depend on the script/application/work-requirements and whatnot.

 

The method I used, is basically bash's implementation of fork (not as capable as c/c++'s), but still do the job in a nicely manner.

It essentially creates a child-process, run it is a sub-shell, with the running command(s) (you can use '()' to encapsulate multiple lines).
