Symlinks, short for symbolic links, are basically shortcuts to individual files or folders. One of the advantages of a symlink is that it can cross filesystems, as it references abstract filenames/directories and not physical locations.
There is a number of ways to create a symlink in cPanel:
1. Via SSH
ln -s /path/to/target /path/to/shortcut
2. Cron
Using the same command NOTE: Make sure that you delete the cronjob once the symlink has been created.
3. PHP function
<?php
$target = '/home/cPanelusername/public_html/index.html';
$shortcut = 'script.html';
symlink($target, $shortcut);
