To find a thing IN as in INSIDE a file? you dont with find.
You use grep.

Code:

grep "something" /somewhere/somefile

man grep for more information.

As said, find is for locating files based on conditions like filename and modification date, while grep is for searching inside them (assuming text files).

Here are a couple of links about using find:
http://mywiki.wooledge.org/UsingFind
http://www.grymoire.com/Unix/Find.html

You can, of course, combine them in order to locate files and then search inside them. But you should first see if you can use grep's own built-in recursive file-matching ability. Read the "info grep" page for details on how to use it.

muralimunna,

Welcome to LQ!
First you need to check the man page of find and grep.

Code:

# man find
# man grep

And I think you can understand the difference between find and grep already told by fukawi1 and David the H.

To help a bit more you can use find to locate files then grep for a particular item in them.

Code:

find /home/bobby -type f -name "*.txt" -exec grep "funny joke" {} \;
