Question

I am dealing with a large data set and it takes some days to run, therefore I use nohup to run my script in terminal.
This time I need to first get a raw_input from terminal then by nohup, my codes starts running. Any suggestion how I can do that?

so first I need to get input from terminal like this

$ python myprogram.py 
enter_input: SOMETHING

then the process should be like this:

$nohup python myprogram.py &

But I want to do this in one step via terminal. I hope my explanation is clear 🙂

Answer 1

I think you shouldn’t your program have read input from stdin, but give it data via its command line.

So instead of

startdata = raw_input('enter_input:')

you do

import sys
startdata = sys.argv[1]

and you start your program with

$ nohup python myprogram.py SOMETHING &

and all works the way you want – if I get you right.
