What is the difference between these UNIX Commands apropos, info, man, and whatis?
To read the documentation on a given command type man whatis or man apropos and the full documentation for the command will come up assuming man is configured on your system. whatis and man are very different commands. Also use goggle if for some reason man is no configured, but it probably is. Note: you can even do it from within yahoo search. Just type man apropos and the manual pages will come up in the search results.
