  • "whatis" displays the one line manual page description for its argument
  • "apropos" searches all the manual pages titles and descriptions for the argument and will list the one line manual page description for all the matching entries it finds.

Therefore "apropos whatis" will find only one matching man page and will report the same information as "whatis whatis" command.

Why are Unix commands simple rather than complex tasks?

UNIX commands are designed to be simple in the first place; they basically do one task per command. To make a more powerful sequence, just put (or pipe) several commands together in a sequence. The ability to use many of the commands in different scenarios just by the command sequence is very powerful; the individual commands do not have to be that powerful or complex, but the result of using several of them in a row makes for a very powerful system.

Most of MS-DOS' commands were based on those of Unix and CP/M. 'cd', 'dir', 'clear', and 'echo' are usually found in both.
