Starting multiple instances of a python script at once from linux command line

I'd like to start a piece of python script a thousand times! instead of trying to start them one-by-one how can I do that from linux command line?

Right now, I am doing it like this:

nohup python test.py &
nohup python test.py &
nohup python test.py &
nohup python test.py &开发者_运维知识库;
nohup python test.py &
...

Thanks in advance.

As a one-liner, in Bash:

for i in {1..1000}; do nohup python test.py & done

I would recommend that you keep the spawning logic in a Python program. Perhaps use the multiprocessing library to do the processes. It'll be hard to manage all of these without some non-trivial scaffolding if you're going to spawn them off in bash.

Simplest is to make a loop using shell script, this will work for anything:

#!/bin/bash
X=0
COUNT=1000
while [ $X -lt $COUNT ]; do
    nohup python test.py &
    X=$((X+1))
done
