How to remove, copy or rename a file with Perl unlink remove rm del delete copy cp rename move mv File::Copy. How about remove? Either one of these would have been an obvious choice. However, it turns out that the command for this function is what seems at first to be a rather unintuitive unlink.

Hence, when you unlink a file, you're really telling the system that the specified file no longer links to any other valid files. Be careful when you use unlink , because if you try to unlink a directory you may very well end up damaging your file system. Now I want to delete the original file and rename the new file to original file name. But somehow it is not happening. You should try testing the output of your commands. The unlink command returns the number of files deleted. You can use this information to test whether the file was deleted or not:.

This will give you an idea whether the unlink is failing or the rename. There's a possibility that the file is still open. If you're adding lines to the file, make sure you use close to close the file handle first:. On Windows, it is especially important to close all file handles before doing anything. Even a read will prevent you from doing anything to the files. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
