Terminal run python script12/16/2023 ![]() You can also detach the screen using Ctrl + a and also return back to the screen using the command screen -r. my_script.pyģ038214 pts/ 1 S+ 0: 00 grep - color= auto my_script.py Command output: 3038184 pts/ 0 S 0: 00 screen -L -Logfile. Let's check the process list during performing the screen command using the next command: ps ax | grep my_script. my_script.py &ĭespite the screen output, logging still saves to our log file. For that, we need to add the next keys: -L for resolving logging and -Logfile path/to/filename.log to indicate log file (by default screenlog.0) screen -L -Logfile. We need a little to modify the command for the identical logging as in the previous heading. ![]() Now we can run our script using the screen command. Use the next command for this: sudo apt install screen Using the 'screen' command for background scriptsĪt first, you need to install the screen. This allows us to return to the script after reconnecting the session. As a solution, you could use nohup or a better screen. For example, if you use ssh session connection, the disconnect will stop our script. I am trying to find a command that will execute commands in the terminal and then output the result. The background script seems to work perfectly, but it's not quite true.

We can see our process using the next command: ps ax | grep my_script. If you run a few scripts with the same name they all will be stopped. It is also possible to kill the process by using pkill command. If you want to stop the script before its ending you can use the kill command: kill PID We save the script's output to the log file, so after running this command we will get output like this in the terminal: 3010186 Print(f "Start time: ")įor running the script use the next command: your/ path/my_script.py > output. For example, a simple script that will have been printing time during the next ten seconds. But at first, we need to prepare our script for this. Now we need some logic that will show us that the script is running in the background. If you want to run a python script in the background you can use an ampersand(&). ![]() This allowed you don't indicate in the terminal that it is a python script. Then I recommend adding a shebang line to the top of this file. At first, we need to add execution permission for this file using the next command: chmod +x my_script.py But at first, we need to prepare our script for this.įor example, we have a python file my_script.py. If you want to run a python script in the background you can use an ampersand(&). ![]()
