Run shell command from launch script

i need to run some system commands ( configurating drivers and similar stuff ) at startup and thought about doing so by including them into the .launch script of my project.

Is this a good idea, is there a simple way to run shell commands ( with root privileges ) from a launch script? Or if not, is there maybe a simple node that i can call to execute shell commands.

Running the command from a shell script would be nice, but how do i call that script via roslaunch? That was what i was looking for in the beginning, reading [].

In principle you can put your commands in any shell script, put it in a ROS package and rosrun that or call it via roslaunch.

One thing that might prevent this from being usable is that you don't have a guarantee that your commands are executed before any others (besides executing different launch files).

By "at startup", you mean once on system boot? In that case, I would use another method (such as /etc/init.d scripts), especially if you need to run as root.
