In Perl, checking if a file is empty is a common task. An empty file is a file with no content, and it can be useful to check for empty files in various scenarios, such as when processing files or handling file input. There are several ways to check if a file is empty in Perl, and each method has its own advantages and disadvantages.
One common way to check if a file is empty is to use the -s operator. The -s operator returns the size of a file in bytes, and if the size is 0, the file is empty.
