How to run Python programs in the background?

Question

I have a Python program that interfaces with the browser, and now I meed to make that as my background process, so that every time I click the button, the program should start running in the background.

Can anyone help me with an easy solution for this?

Answer 1

If you're on a Unix-like system (eg Mac OSX, Linux), the command is python myscript & , which runs the command in the background. In general, in bash (as well as most other shells) if you append a & to your command it runs the command in the background.

Answer 2

Depending on the way your script is launched, backgrounding with & may not necessarily work since there's a non-login shell that might be what's launched - and it would terminate when your browser session terminates. But there's a whole existing thread dedicated to this issue: Calling an external command in Python

What you want to do is spawn either a separate process, or perhaps create a daemon that's started by your browser click.

Answer 3

nohup python filename.py &

Answer 5

You can use http://wwwsearch.sourceforge.net/mechanize/faq.html or use http://curl.haxx.se/libcurl/python/ or use:

* Creating your own HTTP requests using urllib2 standard python library
* Using a more advanced library that provides the capability to navigate through a websit simulating a browser such as  mechanize.

but the "trigger" which will fire the script on Linux, is what YOU have to develop.

Hope this helps.
