mmsg(1)

NAME
mmsg - send commands to the mango Wayland compositor and receive JSON responses

SYNOPSIS
mmsg <command> [args...]
mmsg --help | -h | help

DESCRIPTION
mmsg connects to a running mango(1) compositor via the UNIX domain socket specified by the MANGO_INSTANCE_SIGNATURE environment variable. It sends the given command and prints the JSON reply to standard output. In watch mode it keeps the connection open and prints a stream of updates as they occur.

If --help, -h or help is given, a complete usage summary is printed and the program exits with success.
