Question

subprocess.call(["/home/blah/trunk/blah/run.sh", "/tmp/ad_xml", "/tmp/video_xml"])

I do this. However, inside my run.sh, I have “relative” paths.
So, I have to “cd” into that directory, and then run the shell script. How do I do that?

Answer 1

Use the cwd argument to subprocess.call()

From the docs here: http://docs.python.org/library/subprocess.html

If cwd is not None, the child’s
current directory will be changed to
cwd before it is executed. Note that
this directory is not considered when
searching the executable, so you can’t
specify the program’s path relative to
cwd.

Example:

subprocess.call(["/home/blah/trunk/blah/run.sh", "/tmp/ad_xml", "/tmp/video_xml"], cwd='/tmp')
