Question

In my initial days of using linux I usually had to search google to know the command for
doing a particular task. Once I have the command name, i can view its usage using man command-name.
Similarly I was thinking of some utility which can tell the command to do a particular task if the task to be done is specified as an argument and opens the man page for that command
e.g:

findUtilty "find all files in a directory"
output:
ls
find

I want to know if some utility of that kind exists, if so it will be very handy especially for newbies.
If not then i may like to implement it.

thanx,

Not as nice as you are asking about, but

apropos <keyword>

and

man -k <keyword>

can be very useful.
