Can't get Fabric's detached screen session example to work

Question

I am trying to execute a script on a remote host using a detached screen session. I tried out the example Fabric gives and unfortunately couldn\'t get it to work.

Answer 1

run('screen -d -m yes; sleep 1') works.

Not sure if Fabric or screen are to blame for this behaviour though.

Answer 2

Use it like this:

run('sudo screen -d -m python app.py && sleep 1', pty=True) 

screen -d -m 

Start a session that starts in disconnected mode

Answer 3

Although AVB answer is perfect I'll add a small tip which may help someone like me. If you want to run more than one command put them to a executable file.

This will not work:

run('screen -d -m "./ENV/bin/activate; python run.py; sleep 1"')

So create a run.sh file:

#!/bin/bash
source ENV/bin/activate
python run.py

And use it like run('screen -d -m ./run.sh; sleep 1')
