Running os.system from browser

[Sean Berry]

I have a python program that I want to
be able to run from a browser window.

It gets run in a cron job every day, but
I want my boss to be able to run it whenever
he wants to since the database it uses is
updated many times throughout the day.

I have the following as the first few lines
of a program.

#!/usr/local/bin/python
import os
os.system('/path/to/my/program.py')
print "Content-Type: text/html\n"

The rest of the program just spits out some
simple html. Ths os.system call is what is
breaking the program when I run it from a
browser, because I have commented it out
and the program works.

The program also works from the command
line. How can I fix this problem?

Thanks for any help.

At first glance, this suggests itself:
os.system('/path/to/python /path/to/my/program.py')

I recently wrote a CGI that executes shell commands retrieved from a
HTML form.
It would fail (the dreaded internal error 500) when I used os.system
- but would work fine if I used os.popen2
It's likely that something similar is happening... although perhaps
someone more server savvy could confirm/explain.

os.system() writes to stdout. This means if your
programm.py write to stdout it is send to the browser.

Use os.system('.. >> logfile 2>&1') or popen4
