1. Write good program how to boot operation
2. The program automatically after the operation how to manage such as switching process, kill process
1 now has been basically solved, by creating a XXX. The desktop file which can realize the automatic operation, specific methods online a lot not in detail, the other like what sh scripts to start, make the service start kiss measurement is invalid, may be I level, the food than recommended not to try the
, the results generally like I 2. This problem has no solution, the program automatically run after by ps x command can see py process, but whether you use a kill or fg command are not management, which leads to a big problem, py all print output results in the program we can't see, even if the program has been running,
Don't know which prawn can give a solution or idea for question 2
Gratitude here

The building Lord, solved? I have the same question, carries on the effective management for process such as sonar, the process of how to control stop?CodePudding user response:

I am novice, invented the dichotomy and root don't know why there is a problem, the second root out not to come, the original poster can help me have a look at
