Built a Solaris box today. I had to search for a couple utilities to complete the task, but the OS doesn't come configured with an index. I executed the catman utility to build the windex database. Here's the syntax: #catman -w
Now I can use the man -k pattern to search the database. The -k is the keyword option.
e.g. man -k hme (finds 100Mb NIC interface information)
