The problem is that you are running 2 child, and it's the first subprocess that's changing the directory and then exiting. This actually has little to do with Python specifically. you can see the same thing if you do this: $ pwd /tmp $ cat mycd.sh #!/bin/sh cd /etc $ ./mycd.sh $ pwd /tmp As you can see I am still in tmp. This is because mycd.sh changed to /etc/ but after it exits back to the parent process it is back in /tmp. What you want is to "cd" inside your script itself. os.chdir() does this. -- http://mail.python.org/mailman/listinfo/python-list
