Question

I’m fairly new to programming and I searched the internet for a way to pass bash output to a Python script.

I came up with this in bash.

XAS_SVN=`svn info` 
ssh hudson@test "python/runtests.py $XAS_SVN"

And this in python.

import sys
print sys.argv[1]

When I echo $SVN_INFO I get the result.

Path: . URL:
//svn/rnd-projects/testing/python
Repository Root:
//svn/rnd-projects Repository

However the python script just prints the following.

Why is this and how can I solve this? I the $SVN_INFO variable not of string type?

I know about the subprocess module and the Popen function, but I don’t think this is a solution since the python script runs on another server.

Yes, you need to put in quotes your input to python/runtest.py because otherwise argv[1] gets it only up to the first space. Like this:

ssh hudson@test "python/runtest.py \"$XAS_SVN\""
