- 'dutmp' is a utility used by the Linux Router Project (as far as I
- know nobody else uses it). It dumps the contents of the utmp file to
- STDOUT with each field seperated by a colon. IP addresses are are
- given in hex in native byte order. It is intended that this format
- can then be parsed by shell scripts.
+ 'last' displays a list of the last users that logged into the system.
