It depends on what your exit value is, though. While your shell will probably provide some method for determining the exit status of your process, you're limited to a range of 0-255. If, for example, you've got your Python script exiting with the number of rows in a database, you'll simply overflow. [EMAIL PROTECTED] ~]$ python -c 'import sys; sys.exit(0)' ; echo $? 0 [EMAIL PROTECTED] ~]$ python -c 'import sys; sys.exit(1)' ; echo $? 1 [EMAIL PROTECTED] ~]$ python -c 'import sys; sys.exit(255)' ; echo $? 255 [EMAIL PROTECTED] ~]$ python -c 'import sys; sys.exit(256)' ; echo $? 0 Depending on what you're doing, printing from your Python program and capturing standard out might be a better approach.
