Monty this is a common problem for UNIX users that use Isilon. Sorry to see that no one has ever mentioned this before.  If you do a "#man isi" you get returned the list of isi commands first level. This is the normal UNIX syntax. But since UNIX doesn't allow the use of 2 word lookups, Isilon uses the - between first and second words for additional man pages.  You can do "#man isi-secondcommand" and get man pages on those as well.  By using the dash between first and second level you get a whole new world of documentation.
When I do a man page lookup I always have problems getting past the first level. What is the best way to do this?
#man page lookup issues?
