Revision: 1.17
Committed: Thu Aug 21 13:51:19 2003 UTC (20 years, 9 months ago) by tdb
Content type: text/plain
Branch: MAIN
Changes since 1.16: +56 -26 lines
Log Message: 
Tidy up of my previous commit to make the command line arguments optional.

- Made the default hostname 'i-scream'. Users could have this in their
  hosts file, or they might have a CNAME to their server.
- Added a usage function listing new command line arguments.
- Made the server name and port be options (-s and -p) instead of args.
- Changed the sort option from -s to -o (order).
- Made the host list an option (-l) instead of an argument.
- Added sort options for net and disk io.

This should be slightly tidier than before, and more useful.
