Is there any way to see the exact commands as roslaunch executes?
Is there any way to see the exact commands executed by roslaunch? To echo the commands as they are executed (in much the same way as when we setset -x in bash script)?
Not sure if there exists a package that'd do that for you. You can check all available opetions using
roslaunch -h, launching your launch file in verbose gives you details of processes but not the commands.
