I am very new to shell script. Is this possible to write a script basically starts for example gazebo, rviz and slam? I tried to execute command by python by you can only execute one at a time, executing next requires exiting the current one.

Thanks!

You can launch several nodes using a unique launch file.

For example, this is a launch file that can launch rtabmap_ros, hector_mapping, rviz and other things.

Notice the parts that start with <node (...) > and end with </node> : those mark the limits between the start of the different nodes.

Also, check out the tips for larger projects. This is a far better way to go than using shell scripts. They have their place, but launch files are far more powerful in this context.

Create a [shell script].sh file and write there your "roslaunch [package] [launch file] command"
If you want to add multiple launch files then you can separate them with "&" and "sleep x" (where x is the seconds to sleep between the launch files).
Make the [shell script].sh file executable by using chmod u+x
Run the script file with ./[shell script].sh in the terminal
