2.2.17.2. Command
This option allows you to execute server command-line commands. The user must have
the EWEPRIV_MODSERVER privilege to use this feature. This feature allows the user
nearly complete control of the server (depending on the privileges given to the account
that runs the PHP code) and should only be allowed for users that are
trustworthy. The bottom box is for entering commands. Pressing ENTER or clicking
the "Execute" button will cause the command to be sent to the server. The top box
will then contain the results of that command. Because of the way that this works,
no interactive features (such as editing) are allowed. Only commands that stand alone
will work.
