What about something on using the find command and xargs?

Most shell commands can be piggy-backed on the find command.

And also as mentioned, how and where to find documentation?

pinfo is a nice man page and info page viewer, with Lynx 
like navigation. Much easier than trying to how to use the 
info command.

# pinfo find

1 Introduction
**************

This manual shows how to find files that meet criteria you 
specify, and how to perform various actions on the files that you find. 
The principal programs that you use to perform these tasks are 
`find', `locate', and `xargs'.  Some of the examples in this manual 
use capabilities specific to the GNU versions of those programs.
