  Description
  
  The whatis command looks up a given command, system call, library
  function, or special file name, as specified by the Command
  parameter, from a database you create using the  catman -w com-
  mand.  The whatis command displays the header line from the manu-
  al section.  You can then issue the  man command to obtain addi-
  tional information.
  
  The whatis command is equivalent to using the  man -f command.
  
  Note:	When the /usr/share/man/whatis database is built from the
  InfoExplorer information base using the catman -w command, sec-
  tion 3 is equivalent to section 2 or 3. See the  man command for
  further explanation of sections.
