I'm a beginner. I entered "roscore" in the terminal, but I couln't get response when entering other command. The response I got after I entered "roscore" as follow.

llq@ubuntu:~$ roscore ... logging to /home/llq/.ros/log/eb7e1dc8-e33a-11e0-bfba-f46d04bbb18e/roslaunch-ubuntu-4399.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.

started roslaunch server http://localhost:48966/ ros_comm version 1.6.2


PARAMETERS * /rosversion * /rosdistro


auto-starting new master process[master]: started with pid [4413] ROS_MASTER_URI=http://localhost:11311/

setting /run_id to eb7e1dc8-e33a-11e0-bfba-f46d04bbb18e process[rosout-1]: started with pid [4426] started core service [/rosout]

If I enter other commands like "rosnode list", it doesn't respond. Where the problem is?

roscore blocks your current terminal... You have to use another terminal for your commands.

Hi! Chrimo, thank you very much. I'm new to the English website, so it took me several days to get used. Actually, I solved the problem a few days ago. But I didn't realise that I haven't submitted the question until this morning, just because I haven't logged in. I'm really please to join here.

In my opinion, the ``rosnode list" can be used in different terminals, and outputs the same response. I suggest try again or check the setting of .bashrc. Goodluck.
