file_exists function

In our script before executing a program we need to check if file exists or not. This file check method by using file_exists function check the presence of file from relative path we specify and then returns TRUE of False based on the presence of the file.

We can best use file_exists function along with an if condition.

Here is a sample code.

echo "Yes file is there ";
}else{echo "Sorry no file at $add ";}
