Answer / satchi
Grep is a filter used for pattern matching in shell script.
It searches for the patern if file name is give, or else it
will look for the input data using pipe(|)
Syntax:
1. Grep <patern to search> <Filename>
2. cat <filename> | grep <Patern to search.>
we can use -i option to ignore case sensitiveness.There are
so many options available.you have to explore that.
