roslaunch command doesn't run

This is likely because the robot has not received the permissions to run the file. First, navigate to the directory containing the file using ls and cd. The file should be written in grey text instead of grey.

Next, run the below line. <FILE_NAME> should be replaced by the name of the file you want to run with roslaunch.

$ sudo chmod +x 777 <FILE_NAME>

Now, when typing ls, the file name should have turned green. The roslaunch command should now work!
