Yes and no: any of the keys can be in any location, but their arguments
must follow the key list in the order that the keys appear. For example:
tar cbf 20 foo.tar /dev/null
tar: Removing leading `/' from member names
tar cbf foo.tar 20 /dev/null
tar: foo.tar: Invalid blocking factor
Try 'tar --help' or 'tar --usage' for more information.
In the first case a foo.tar file is created with a blocking factor of
20, and in the second case the command blew up because the filename is
before the blocking factor. With less luck, the swapped arguments
wouldn't fail immediately, doing who-knows-what to the system. :)
