Overview:

The cPanel & WHM installation process adds important scripts to your server’s /usr/local/cpanel/scripts directory. To run a script, enter its location on the command line. For example, to run the update script, run the following command:

/usr/local/cpanel/scripts/upcp

To display help for a script, add the --help argument. For example, to display help for the update script, run the following command:

/usr/local/cpanel/scripts/upcp --help
Warning:
  • When you run a script, you must use the script’s full file path, even if you run the script in the /usr/local/cpanel/scripts directory.

  • Do not use scripts in the /usr/local/cpanel/scripts directory that we do not list in this document. You may damage your server if you run those unlisted scripts.
