I'm writing an XBMC script, and for part of it, I need to run a command-line utility and get back the output from the utility.
Here's the method I tried first:
However, this method kills the XBMC script and the debug log says:
So I then decided to try this method:
This time, the debug info on crash was:
Now, both these first two methods ran just fine from a test script (using Ubuntu's native Python) - but both failed within Xbmc.
So I resorted to this:
This works within Xbmc. Hurrah!
- but it's a hack!
Why won't my first two techniques work? Is there any way to run a command-line tool and directly capture the stdout, without resorting to temp files?
My XBMC platform is PC running Ubuntu Jaunty, and my currently installed xbmc is 9.04.3+svn23754-jaunty1.
Thanks.
Here's the method I tried first:
Code:
out = os.popen("/external/cmd -arg").read();
Code:
OSError: (0,'Error')
So I then decided to try this method:
Code:
out = subprocess.Popen(["/external/cmd -arg"], shell=True, stderr=subprocess.PIPE, stdout=subprocess.PIPE).communicate()[0]
Code:
OSError: [Errno 10] No child processes
Now, both these first two methods ran just fine from a test script (using Ubuntu's native Python) - but both failed within Xbmc.
So I resorted to this:
Code:
os.system("/external/cmd -arg > /tmp/temp.out");
out = open("/tmp/temp.out").read();
This works within Xbmc. Hurrah!
