Hello! Find command

The command find is a command-line utility that searches one or more directory trees of a file system, locates files based on some user-specified criteria.

The following example will print out the files that find returns that contain the text "lime":

$ find . | grep "lime" 

Now, by using the exec switch with the find command, we can find all the files that contain the search string ("lime").

$ find . -exec grep "lime" {} \;
