All you need to do is + enter the necessary command definition into 'commands.conf' and implement + the actual command that will be called. Such a command can typically be a + shell script or a Perl program. Anything that command writes to stdout will + be displayed on a result screen after executing the command. In order to + avoid error messages going to stderr, command definitions should redirect + stderr to stdout (see FORMATS). + + WARNING: THE COMMANDS DEFINED IN 'commands.conf' WILL BE EXECUTED UNDER THE + ======= SAME USER ID THAT VDR IS RUNNING WITH.
