(1) create a sed script which makes all comments consistent.
Comment lines begin with either “//” or “#” and can have any number of whitespaces before and after the “//” or “#”. Replace these comment lines with only “//” followed by a single space and the rest of the original comment. Finally, remove any lines that begin with a “%”. Include the command to run the script for a file named file1.php (contents below) and print output to file1Clean.php.
