XMMS2-LAUNCHER(1)					      General Commands Manual						 XMMS2-LAUNCHER(1)

NAME
xmms2-launcher - XMMS2 daemon launcher SYNOPSIS
xmms2-launcher [ -? / --help ] xmms2-launcher [ -l logfile / --logfile= logfile] [ -P pidfile / --pidfile= pidfile] [ --verbose ] DESCRIPTION
XMMS2 is a redesign of the XMMS (http://www.xmms.org) music player. It features a client-server model, allowing multiple (even simultane- ous!) user interfaces, both textual and graphical. All common audio formats are supported using plugins. On top of this, there is a flexi- ble media library to organise your music. xmms2-launcher starts xmms2d(1) in the background. The main feature is that it does not exit until the IPC system of XMMS2 is available, meaning that as soon as the xmms2-launcher process has exited successfully xmms2d(1) is ready to accept commands. xmms2-launcher includes command line options to change the way in which the daemon is invoked. These options are currently recognised: -l logfile / --logfile=logfile Write log file to logfile instead of the default log file location - P pidfile / --pidfile=pidfile Write the pid of xmms2d to the file specified by pidfile --verbose Increases the vebosity of xmms2-launcher -? / --help Show help options FILES
$XDG_CACHE_HOME/xmms2/xmms2d.log The default location for a file where the log output of xmms2d(1) is redirected. Usually ~/.cache/xmms2/xmms2d.log. SEE ALSO
xmms2d(1), http://xmms2.xmms.org HISTORY
The XMMS2 Project was started by Tobias Rundstrom and Anders Gustafsson. It is developed with their lead by a small group of contributers from all over the world. AUTHOR
