Actually, it is quite simple. Just use stdin to take the python file. ~/linux/test/python/man/library/sys/path$ cat.sh main.py subdir/main.py ==> main.py <== #!/usr/bin/env python import sys print sys.path ==> subdir/main.py <== #!/usr/bin/env python import sys print sys.path ~/linux/test/python/man/library/sys/path$ diff <(python - < main.py) <(python - < subdir/main.py) -- Regards, Peng -- http://mail.python.org/mailman/listinfo/python-list
