Launching multiple scripts without waiting the end of the previous using anacron

  • 772

On a small server, I would like to launch a selenium webdriver and a python script which will use the selenium webdriver consecutively at boot, without waiting the end of the other (of course).

I therefore added the following lines to my /etc/anacrontab:

@daily  1       webdriver       java -jar ~/selenium-server-standalone-3.4.0.jar &
@daily  2       wifi_manager    ~/script.py &

By doing this, the two processes are however terminated:

Jun 24 01:09:51 david anacron[441]: Job `webdriver' started
Jun 24 01:09:51 david anacron[441]: Job `webdriver' terminated
Jun 24 01:10:51 david anacron[441]: Job `wifi_manager' started
Jun 24 01:10:51 david anacron[441]: Job `wifi_manager' terminated

How should I start them, in order to have them running permanently?

EDIT: I now have:

@daily  1       wifi_manager    bash -c '$dir/start_driver.sh & (sleep 30 && $dir/dis-enable_wifi.py) &'

But I still get: Jun 24 14:02:56 david anacron[444]: Job wifi_manager' started Jun 24 14:02:56 david anacron[444]: Jobwifi_manager' terminated

The start_driver.sh consists in:

cd $dir # needed in order to have log saved there...
nohup java -jar selenium-server-standalone-3.4.0.jar &

Basically, I have to start the selenium webdriver, wait until it is ready and then run the python script for the whole day.

If I run the command I put in the anacrontab from terminal it just works fine.

  1. Consider starting a shell and running those scripts in background, something like

     bash -c '/home/user/script.py & another_script.sh &'
