Using the grep command

This is how we can use the power of grep command to find 
the particular word in the file.

Syntax is:

grep [options] PATTERN [FILE

Example:

If I wanted to find the word "Name" in the file info.txt 

we can form the grep command as below

grep Name ./info.txt

If you want to know the line number just add the option -n. 

The above command is modified as below.

grep -n Name ./info.txt
