And how do I look up the words in Full, not short, command man page? so that I can look up chmod by searching the word symbolicThanks

You are looking for the -K option for man:       -K, --global-apropos              Search for text in all manual pages.  This is a brute-force search, and is likely to take  some  time;  if              you  can,  you  should  specify  a section to reduce the number of pages that need to be searched.  Search              terms may be simple strings (the default), or regular expressions if the --regex option is used.This will, by default, queue all of the man pages that match your search pattern up for opening in your $PAGER. To just view the list of man pages that contain your search term, pass the -w option as well:       -w, --where, --location              Don't actually display the manual pages, but do print the location(s) of the source nroff files that would              be formatted.Depending on your search term, this could return a lot of results...
