Save automatically rosbag after a certain interval

edit

Also, there is the rosbag command line API : http://wiki.ros.org/rosbag/Commandlin...

```

-d, --duration

Specify the maximum duration of the recorded bag file.

$ rosbag record --duration=30 /chatter
$ rosbag record --duration=5m /chatter
$ rosbag record --duration=2h /chatter

```

and :

```

--split

Split the bag when maximum size or duration is reached

$ rosbag record --split --size=1024 /chatter
$ rosbag record --split --duration=30 /chatter
$ rosbag record --split --duration=5m /chatter
$ rosbag record --split --duration=2h /chatter

```

something like :

rosbag record /my_topic --split --duration=30

The rosbag will be split every 30sec, thus creating a new bag file every 30sec

Nice! It worked! Thank you

Im glad it helped! You can mark the answer as correct by clicking the tick mark on the left side above.

Hey, Can we specify with command to run for 1 hour but split after 10 minutes or when the size of the bag reach some values? So record for 1 hour each 10 minutes and as a result able to get 6 bag files. Is it possible? Something like this https://github.com/ros/ros_comm/issues/4
