How to Open and read from text files using Perl Language?

It's easy to read the file but Perl requires you to open the file first and then get to read the same. Usually when we do read, write and open operation on file. We tend to add the code in the try and catch blocks in most programming languages.

So basically in case of the perl we make use of the following syntax most of the time.

open() or die()

As you can see you have to check if the file is successfully opened and then call the die() method.

Its better to avoid writing the code without die() method. Also make sure to save the content of the file in some string or variable and avoid reading it through buffer.
