Find/Search a string using Batch File programming

This tutorial is about Find a string from any file or a command output. This tutorial is very useful while processing a output or storing an output to a file and then searching for a specific string in it.

For example, If you want to find your system configurations like os, build, ip or any output, You can use find to get that easily.
Syntax:
FIND [/V] [/C] [/N] [/I] "string" [pathname(s)]
"string" : The text string to find (must be in quotes).
[pathname] : A drive/file(s) to search.
/V : Display all lines NOT containing the specified string.
/C : Count the number of lines containing the string.
/N : Display Line numbers.
/I : Ignore the case of characters when searching for the string

Error Levels:
0 if the string is found in any of the files specified
1 if not found
