Process killed after closing terminal SSH

Question

I'm trying to clear facebook cache on my server every 2 seconds so i logged in the SSH and i run this command

while true; do sleep 2; curl -F id="http://twd.ma" -F scrape=true -F access_token='token' -F appID=appID https://graph.facebook.com; done &

And every thing worked fine and the cache started to be cleaned every 2 seconds. However, when i close the Terminal SSH the cache stop being cleaned and i think the process is killed, what should i do please?

Your command will stop executing because when you log out, the shell is lost. The '&' means that the script runs in background "as long as the shell is active"

You can do the following: Write your script into a file, i.e. clearcache.sh and omit the '&'

#!/bin/bash
while true; do
sleep 2
curl -F id="http://twd.ma" -F scrape=true -F access_token='token' -F appID=appID https://graph.facebook.com
done

Write the path to your script into /etc/rc.local

/path/to/clearcache.sh > /dev/null 2&>1 &

The ' >/dev/null 2&>1 means that all output that your script produces will be deleted.

and is there a better way without a script? – Jan 15 '18 at 21:26
you could use a screen session for that see https://stackoverflow.com/questions/7049252/how-to-create-a-screen-executing-given-command – Michael Schönwiese Jan 15 '18 at 21:31

If screen is available to you then you can start a screen session by running screen, run your commands, then press ctrl-a ctrl-d to detach the session.

When you log in later you can issue screen -r to reconnect to the detached session.
