How can I rejoin a process running

Question

I am very new to using Linux. I have a 'machine' on Amazon and I was trying to learn how to use Python on this machine. I started running Python—had to step away for a few minutes and the connection was reset. I rejoined the connection and started wondering if the Python process was running. I poked around and submitted the

ps -ewwo pid,args | grep python 

and I discovered all of this

root@mymachine:/# ps -ewwo pid,args | grep python
906 python
1118 grep python
2450 /usr/bin/python /usr/lib/mailman/bin/mailmanctl -q start
2451 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=ArchRunner:0:1 -s
2452 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=BounceRunner:0:1 -s
2453 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=CommandRunner:0:1 -s
2456 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=IncomingRunner:0:1 -s
2462 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=NewsRunner:0:1 -s
2468 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=OutgoingRunner:0:1 -s
2469 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=VirginRunner:0:1 -s
2470 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=RetryRunner:0:1 -s

From what I have found I think that Python is still running and it has a process ID of 906.

I would like to know

1. Will it die on its own at some point (not likely from what I understand)
2. Can I rejoin it somehow?
3. Am I even correct in my conclusion and if I can't rejoin it can I kill it?

Answer 1

Will it die on its own at some point (not likely from what I understand)

Not unless Amazon has some daemon set up to do that sort of thing.

Can I rejoin it somehow?

Nope. EDIT: Looks like the program reptyr can do it, but it's not a standard command, so you'll have to install it yourself.

... and if I can't rejoin it can I kill it?

Yes. If killall is available, and this is Linux, you can just do killall python, or pkill python if it isn't available. If that doesn't kill them, you can do killall -KILL, pkill -KILL, or kill -KILL instead to force them to die.
