FvwmCommand

FvwmCommand is a command line tool that allows you to send commands directly to fvwm from any terminal or shell by talking to the FvwmMFL socket. FvwmCommand then sends the command you give it directly to fvwm. For example to launch FvwmPager from a terminal:

FvwmCommand Module FvwmPager 0 3

You can send any command to fvwm, using FvwmCommand <command>. In order for FvwmCommand to function, FvwmMFL must be running to give FvwmCommand a socket to talk to fvwm though. So make sure you have started FvwmMFL from your start function:

AddToFunc StartFunction I Module FvwmMFL

Note: In fvwm3, if FvwmPrompt is installed, you should use that instead. FvwmPrompt can both send single commands exactly like FvwmCommand, it can also open an interactive shell that can be used to talk to fvwm.
