MOC(1) Music On Console MOC(1)

MOC - Console audio player

mocp [OPTIONS] [FILE|DIR ...]

MOC is a console audio player with simple ncurses interface. It supports OGG, WAV, MP3 and other formats. Just run mocp, go to some directory using the menu and press enter to start playing the file. The program will automatically play the rest of the files in the directory.
With no options and no file arguments the program begins in current directory, or in MusicDir if the StartInMusicDir option is set in the configuration file. If you give a directory on the command line, MOC will try to go there. If a playlist is given, then it is loaded. With multiple files, playlists or directories, everything will be added to the playlist recursively (including the contents of any playlist given). (Note that relative paths in playlists are resolved with respect to the directory of the playlist, or of the symlink being used to reference it.)

If an option can also be set in the configuration file the command line overrides it (but see the -O option for the list-valued configuration options exception).
-D, --debug
Run MOC in debug mode. The client and server log a lot of information to debug files. Don't use this; the server log is large. This is only available if MOC was compiled without --disable-debug.
-S, --server
Run only the server and exit.
-F, --foreground
Implies -S. Run the server in foreground and log everything to stdout.
-R NAME[:...], --sound-driver NAME[:...]
Use the specified sound driver(s). They can be OSS, ALSA, JACK, SNDIO or null (for debugging). Some of the drivers may not have been compiled in. This option is called SoundDriver in the configuration file.
-m, --music-dir
Start in MusicDir (set in the configuration file). This can be also set in the configuration file as StartInMusicDir.
-q, --enqueue
Add files given after command line options to the queue. Don't start the interface.
-a, --append
Append files, directories (recursively) and playlists given after command line options to the playlist. Don't start the interface.
-c, --clear
Clear the playlist.
-p, --play
Start playing from the first item on the playlist.
-f, --next
Request playing the next song from the server's playlist.
-r, --previous
Request playing the previous song from the server's playlist.
-s, --stop
Request the server to stop playing.
-x, --exit
Bring down the server.
-P, --pause
Request the server to pause playing.
-U, --unpause
Request the server to resume playing when paused.
-G, --toggle-pause
Toggle between play and pause.
-k [+|-]N, --seek [+|-]N
Seek forward (positive) or backward (negative) by N seconds in the file currently being played.
-T THEME, --theme THEME
Use a theme file. If the path is not absolute, the file will be searched for in /usr/share/moc/themes/ (depends on installation prefix), ~/.moc/themes/ and the current directory.
-C FILE, --config FILE
Use the specified configuration file instead of the default. As this file can specify commands which invoke other applications MOC will refuse to start if it is not owned by either root or the current user, or if it is writable by anyone other than its owner.
-O NAME[+]=VALUE, --set-option NAME[+]=VALUE
Override configuration option NAME with VALUE. This option can be repeated as many times as needed and the option name is not case sensitive. Most option values are set before the configuration file is processed (which allows the new values to be picked up by substitutions); however, list-valued options are overridden afterwards (which gives the choice of whether the configured values are replaced or added to).
See the example configuration file (config.example) for a description of the options available.
Examples:  -O AutoNext=no
           -O messagelingertime=1 -O XTerms+=xxt:xwt
Note that MOC does not perform variable substitution as it does for values read from the configuration file.
-M DIR, --moc-dir DIR
Use the specified MOC directory instead of the default. This also causes the configuration file from that directory to be used. This can also be specified in the configuration file using the MOCDir option.
-y, --sync
This copy of the interface will synchronize its playlist with other clients. This option is called SyncPlaylist in the configuration file.
-n, --nosync
This copy of the interface will not synchronize its playlist with other clients (see above).
-A, --ascii
Use ASCII characters to draw lines. (This helps on some terminals.)
-i, --info
Print the information about the file currently being played.
Print information about the file currently being played using a format string. Replace string sequences with the actual information:
%state     State
%file      File
%title     Title
%artist    Artist
%song      SongTitle
%album     Album
%tt        TotalTime
%tl        TimeLeft
%ts        TotalSec
%ct        CurrentTime
%cs        CurrentSec
%b         Bitrate
%r         Rate
It is also possible to use variables from the FormatString configuration file option.
-e, --recursively
Alias of -a for backward compatibility.
-h, --help
Print a list of options with short descriptions and exit.
-V, --version
Print the program version and exit.
-v [+|-]N, --volume [+|-]N
Adjust the mixer volume. You can set (-v 50) or adjust ( -v +10, -v -10).
-t OPTION[,...], --toggle OPTION[,...]
-o OPTION[,...], --on OPTION[,...] -u OPTION[,...], --off OPTION[,...] Followed by a list of identifiers, these will control MOC's playlist options. Valid identifiers are shuffle, repeat and autonext. They can be shortened to ' s', 'r' and 'n' respectively.
Example:  -t shuffle,r,n
would toggle shuffle, repeat and autonext all at once.
-j N{s|%}, --jump N{s|%}
Jump to some position in the current file. N is the number of seconds (when followed by an ' s') or the percent of total file time (when followed by a ' %').
Examples:  -j 10s, -j 50%

MOC directory for the configuration file, socket, the pid file and other data.
Configuration file for MOC. The format is very simple; to see how to use it look at the example configuration file ( config.example) distributed with the program. The example file fully describes all the configuration options, and so is a useful reference when using the -O option. As this file can specify commands which invoke other applications MOC will refuse to start if it is not owned by either root or the current user, or if it is writable by anyone other than its owner.
/usr/share/moc/themes Default directories for the theme files.
Default directories for the audio decoder plugins.
mocp_server_log Client and server log files. These files are created in the directory in which the client and server are started. (Also see the -D option.)

Command line options that affect the server behaviour (like --sound-driver) are ignored if the server is already running at the time of executing mocp. The user is not warned about this.
