ROS execute multiple commands from file

ROS execute multiple commands from file

Is there any way to run these commands consecutively automatically?

roscd stereo_camera rosparam load marvin_cameras.yaml rosrun stereo_camera stereo_camera __name:=bumblebeeLeft rosrun stereo_camera stereo_camera __name:=bumblebeeCenter roslaunch openni_launch_marvin kinect_left.launch roslaunch openni_launch_marvin kinect_center.launch

It might be a good idea to try http://answers.ros.org/questions/. I'd say the main problem is that rosrun and roslaunch block the terminal, right? Therefore, some forking might solve it.

@Humungus - Why suggest someone goes outside of Stack Exchange when we have our very own robotics site here?

@MarkBooth True, I've missed that one.

You can either write a single launch file which runs your desired nodes/launch-files with delays as stated here, or you can just write a bash script which should look like this:

#!/bin/bash roscd stereo_camera rosparam load marvin_cameras.yaml rosrun stereo_camera stereo_camera __name:=bumblebeeLeft & rosrun stereo_camera stereo_camera __name:=bumblebeeCenter & roslaunch openni_launch_marvin kinect_left.launch & roslaunch openni_launch_marvin kinect_center.launch & wait

Assuming that your script is named script.sh, you have to make it executable via chmod +x script.sh and then run it via ./script.sh.
The & signs send the commands to the background, while the wait command waits until all programs in the background finished.

script.sh

chmod +x script.sh

./script.sh

&

wait
