CMUS(1)

NAME
cmus - C* Music Player

SYNOPSIS
cmus [options]

DESCRIPTION
cmus is a lightweight ncurses music player. It supports various output methods by using dynamically-loaded output plugins. cmus has configurable keybindings and can be controlled externally using cmus-remote(1).

OPTIONS
--listen ADDR
    Listen on ADDR (UNIX socket) instead of $CMUS_SOCKET or $XDG_RUNTIME_DIR/cmus-socket. ADDR must be a UNIX socket or host[:port].
    WARNING: Using host[:port] is insecure even with a password! It may be on a LAN if you want multiple users to be able to control cmus. Never expose cmus to the internet.
    NOTE: Don't use this option to run multiple instances as the same user. Doing so would corrupt the track metadata cache.
--passwd PASSWD
    Set the password for TCP/IP connections. Required if listening on host[:port]. Used in conjunction with --listen.
--plugins
    List available plugins and exit.
--show-cursor
    Always display the cursor. This is useful for screen readers.
--help
    Display usage information and exit.
--version
    Display version information and exit.

VIEWS
There are 7 views in cmus. Press keys 1-7 to change active view. Library view (1)
    Displays all tracks in the library. Tracks are sorted and displayed in a tree grouped by artist/album. Artist sorting is done alphabetically. Albums are sorted by year.
Sorted library view (2)
    Displays the same content as view 1, but as a simple list automatically sorted by user criteria.
Playlist view (3)
    Displays editable playlists with optional sorting.
Play Queue view (4)
    Displays upcoming tracks. These tracks are played before anything else (i.e. the playlist or library). Once the queue is empty, playback will resume from the last position in the library.
Browser (5)
    Displays the directory browser. In this view, music from the filesystem can be added to the library, active playlist, or queue.
Filters view (6)
    Lists user-defined filters.
Settings view (7)
    Lists keybindings, unbound commands and options. Remove bindings with D or del, change bindings and variables with enter, and toggle variables with space.

COMMAND LINE
Everything in cmus is implemented as commands which can be typed at the command line or bound to a key. To enter command mode type :. To execute a command, press ENTER, and to cancel, press ESC or CTRL-C. Use up/down arrows to browse the command history. Use TAB to complete commands and parameters. You don't need to type the full command name if it is unambiguous (no other commands starting with the same characters). Examples:
    # add files, short for ':add ~/music'
    :a ~/music
    # change output plugin
    :set output_plugin=oss
    # start playing
    # you could just press 'x' which is the default
    # binding for this command
    :player-play
    # clear current view (library, playlist or play queue)
    :clear

SEARCHING
Search mode works like the command mode. To enter search mode, press / and type the query then press ENTER. Press n to move to the next result or N for the previous one. Type ? to search backwards. In views 1-4 the query is matched against the artist, album and title tags. Type //WORDS or ??WORDS to search only artists/albums in view 1 and only titles in views 2-4. If the file doesn't have tags, words are compared to the filename excluding the path. Searching also works in views 5-7.

PLAYLIST EDITING

  Selecting Tracks
Editing commands affect the currently marked tracks. If there are no marked tracks, the currently selected track (or selected artist/album in view 1) is used. To mark the selected track, press SPACE. Marked tracks appear with a gray background. You can only mark tracks in the list views (2-4).

  Copying Tracks Between Views
You can copy marked or selected tracks in views 1-5.

a   copy tracks to the library (1-2)

y   copy tracks to the marked playlist (3)

e   append tracks to the play queue (4)

E   prepend tracks to the play queue (4)

  Moving Tracks
In views 2-4, tracks can be moved within the list. Note that moving is disabled if the view is auto-sorted (see lib_sort and pl_sort options). Pressing p moves marked tracks to the position immediately after the selected track. P moves them to the position immediately before the selected track. If there are no marked tracks, the selected track is moved down (p) or up (P). Note that changing active filters in view 2 reloads it, losing any changes made to the track order.

  Removing Tracks
Press D or delete to remove the marked or selected tracks in the current view (1-4). The tracks will be removed immediately from the view without asking for confirmation. In the browser and filters views, the same keys are used to remove a file or filter after asking for confirmation.

STATUS LINE
The right hand side of the status line (second row from the bottom, black text on a grey background) consists of the following fields:
aaa_mode & play_sorted & play_library | continue follow repeat shuffle
NOTE: aaa_mode and play_sorted will be only displayed if play_library is true because these are meaningless when playing the playlists (view 3). Pressing m, o, M, C, r and s should make it easier to understand what these fields mean. See the CONFIGURATION OPTIONS section for more information about these options.

LIBRARY VIEW SORTING
The library view (the tree-like one; not the sorted library view, which is configured with lib_sort - see CONFIGURATION OPTIONS), is sorted automatically using tags from the audio files. Note: Albums which feature various artists (e.g. samplers or compilations) are treated specially. If an album artist tag or the ID3v2 TPE2 frame is set, it will be used instead of the real artist name. Otherwise, cmus determines if the album is a compilation (if albumartist or artist are set to Various Artists, Various, VA, or V/A; or if compilation or partofacompilation are set to a truthy value; or if the ID3v2 TCMP frame is set). If so, the artist is named <Various Artists>. Note: If the filename is a URL, the artist/album tags are set to <Stream>. If it is a file, cmus sets the artist and/or album tags to <No Name> if they are not already set. These names will be treated the same way as other names for sorting. In general, three levels of sorting are used in the library view: the artist name, then the album, and finally the track itself. First, cmus sorts alphanumerically by the value of the artist tag. If a special sorting tag is available, its value will be used instead. Next, cmus sorts by the album. Tracks are grouped by the album name, and the groups are sorted by the date of the first track, then alphanumerically by the name of the album. If the date header is not set, the album will be placed on top of the list. Finally, each album is sorted by the track discnumber, tracknumber, then filename (not the track name).

COMMANDS
This section describes cmus' commands, which can be bound to keys and mouse events, put in configuration files, executed in command mode, or passed to cmus-remote. Optional parameters are in [brackets], required parameters in <angle brackets> and default key bindings are (parenthesized). add [-l] [-p] [-q] [-Q] <file|dir|url|playlist>
    Adds file/dir/url/playlist to the specified view or the current view.

    -l  add to library

    -p  add to playlist

    -q  add play queue

    -Q  prepend to play queue
    Supported files are based on the loaded input plugins.
    Supported URLs: Shoutcast (http://...), CDDA (cdda://...).
    Supported playlist types: plain, .m3u, .pls.
bind [-f] <context> <key> <command>
    Adds a key binding.

    -f  overwrite existing binding
    Valid contexts: common (i.e. all views), library (1-2), playlist (3), queue (4), browser (5), filters (6)
    There's one context for each view. Common is a special context on which bound keys work in every view.
    You can override specific keys in common context for a view. For example i selects the current track in views 1-3 but in browser it is overridden to toggle showing of hidden files.
    When setting custom bindings in $XDG_CONFIG_HOME/cmus/rc, it is recommended to use the -f option, or else bind may fail due to an existing binding in the autosave or system-level config files.
    Hint: You can press tab from command mode to expand contexts, keys, and commands.
browser-up (backspace)
    Navigates the browser view to the parent directory (5). This command only makes sense to be bound to the browser key context although it's possible to use this even if browser view is not active.
cd [directory]
    Changes the current working directory. Also changes the directory displayed in the browser view.
clear [-l] [-p] [-q]
    Removes all tracks from a single view.

    -l  clear library

    -p  clear playlist

    -q  clear play queue
    If a view is not specified, the current view is used.
colorscheme <name>
    Changes the color scheme. Color schemes are found in /usr/share/cmus/ or $XDG_CONFIG_HOME/cmus/ and have the extension .theme.
echo <arg>...
    Displays the arguments on the command line.
    {} it is replaced with file name of the first selected track.
factivate <user-defined-filter>...
    Selects and activates the given user defined filters (displayed in the filters view). Filter names are separated by spaces. This command is mostly useful when bound to a key to change active filters quickly. If no arguments are provided, all filters are deactivated.
    Prefix a filter name with ! to negate it.
filter <filter-expression>
    Temporarily filters a library view. The filter is not saved (use fset and factivate for that).
fset <name>=<filter-expression>
    Defines or replaces an existing filter and adds it to the filters view (6).
help
    Shows information about help files.
invert
    Inverts the marking of tracks in playlist and queue views. See mark and unmark.

push [text]
    Enters command mode with the command line pre-set to text. Example:
        bind common w push filter artist=
    Text can contain spaces, which will be used as-is (e.g. trailing spaces will be preserved). If no text is given, it defaults to a blank command line.
    This command can only be used from a keybinding.

    Redraws the terminal window.
reshuffle
    Reshuffles the shuffle lists for both library and playlist views.
run <command>
    Runs a command for the marked tracks OR the selected one if none marked.
    By default file names are appended to the command. If the command contains {} it is replaced with list of filenames.
    Note: In view 1 you can run a command for all files in the selected album or artist.
save [-e] [-l] [-L] [-p] [-q] [file] (:w)

search-start
    Enters search mode. Cannot be used directly from command mode.
    This is similar to live-filter, except it is temporary and only selects the current match rather than filtering the entire view.

    Only works in views 1-2 and 5, does nothing in other views.
win-update-cache [-f]
    Same as update-cache, but only for marked / selected tracks. Only works in views 1-2, does nothing in other views.
wq
    See quit. Intended for use from command mode.

CONFIGURATION OPTIONS
This section describes configuration options used by cmus. These options can be changed using the set and toggle commands. Default values are (parenthesized), and the possible values are in [brackets]. auto_expand_albums_follow, auto_expand_albums_search, auto_expand_albums_selcur (true)
    Always expand an artist and select the album when following the currently played track or performing actions such as "search" or "go to current track". This option is tightly coupled to the show_all_tracks option. Any "auto_expand_albums_* = false" implies "show_all_tracks = true".
auto_reshuffle (true)
    Reshuffle a playlist when the end of a shuffled list is reached.
aaa_mode (all) [all, artist, album]

    Use replay gain limiting when clipping.
replaygain_preamp (0.0)
    Replay gain preamplification in decibels.
resume (false)
    Resume playback on startup.
rewind_offset (5) [-1-9999]

scroll_offset (2) [0-9999]
    Minimal number of screen lines to keep above and below the cursor.
show_all_tracks (true)
    Display all tracks of the artist when the artist is selected in the tree view. This option is tightly coupled to the auto_expand_albums_\ options. "show_all_tracks = false" implies "auto_expand_albums_* = true".
show_hidden (false)
    Display hidden files in browser.
show_current_bitrate (false)
    Display current bitrate in the status lines.
show_playback_position (true)

show_remaining_time (false)
    Display remaining time instead of elapsed time.
shuffle (off) [off, tracks, albums]

    off Play all tracks in order. See also lib_sort and pl_sort.

    tracks
        Play all tracks in the library or playlist in a shuffled order.

    albums
        Play each library album to completion before shuffling to the first track of another library album. In playlists this option falls back to tracks behaviour.
    Filters and aaa_mode can be used to limit the items available for play. Note that shuffle=albums will have no effect with aaa_mode=album.
skip_track_info (false)
    Don't load metadata when adding tracks. Useful when using network file system and having huge amount of files. Tags can be loaded using 'update-cache' or 'win-update-cache' commands.
softvol (false)
    Use software volume control.
    Note: You should probably set this to false when using ao as output_plugin to output to wav files.
softvol_state (100 100)
    Used to save left and right channel values for software volume control. Two integers in range 0..100 separated by a space. This option is not usually changed directly since vol command does same thing if softvol is true.
start_view (tree) [tree, sorted, playlist, queue, browser, filters, settings]
    Specify the view that gets shown when cmus starts.
status_display_program () [command]
    This command, if set, is run for every status change. It can be used to display currently playing track on desktop background or panel for example. See /usr/share/doc/cmus/examples/cmus-status-display.

    Percentage of the window width to use for left pane.
tree_width_max (0) [0-9999]
    Restrict the size calculated from tree_width_percent. 0 disables this option.
    This affects the tree in the library view and the playlist list in the playlist view.
    Note that this value will be further constrained by the window width and/or the minimum tree size.
    For example, to set a fixed size of 60 columns:
        set tree_width_percent=100
        set tree_width_max=60
    Or, to be 33% wide, but at most 60 columns
        set tree_width_percent=33
        set tree_width_max=60
    Or, to always be 33% wide where possible (the default behavior):
        set tree_width_percent=33
        set tree_width_max=0
wrap_search (true)
    Controls whether the search wraps around the end.

  Colors
Color is an integer in range -1..255. The following color names are recognized: Terminal's default color, -1
    default
Fg & bg, 0..7
    black, red, green, yellow, blue, magenta, cyan, gray
Fg, 8..15
    darkgray, lightred, lightgreen, lightyellow, lightblue, lightmagenta, lightcyan, white

  Attributes
Attributes is a set of names "standout|bold": default does nothing, if you put it with other attributes the other attributes will be used. standout makes the text standout. bold makes the text bold. reverse reverses the text colors. underline underlines the text. blink makes the text blink.

  Format Strings
Format strings control display of tracks in library, playlist and play queue views. Note: altformat_* options are used when there are no tags available. Special Keys:
    %a %{artist}
    %A %{albumartist}
    %l %{album}
    %D %{discnumber}
    %n %{tracknumber}
    %X %{play_count}
    %t %{title}
    %g %{genre}
    %c %{comment}
    %y %{date}
    %d %{duration}
    %f %{path}
    %F %{filename}
        %{albumduration}
        %{originaldate}
        %{maxdate}
        %{bpm}
        %{bitrate}
        %{codec}
        %{codec_profile}
        %{rg_track_gain}
        %{rg_track_peak}
        %{rg_album_gain}
        %{rg_album_peak}
        %{arranger}
        %{composer}
        %{conductor}
        %{lyricist}
        %{performer}
        %{remixer}
        %{label}
        %{publisher}
        %{work}
        %{opus}
        %{partnumber}
        %{part}
        %{subtitle}
        %{media}
    %!
        prior text is of lower importance and may be shortened if needed (use at most once)
    %=
        start align right (use at most once)
    %%
        literal %
    %?
        literal ?
You can use printf style formatting (width, alignment, padding). As an extension, the width can have a %-suffix, to specify a percentage of the terminal width.
To see current value of an option type :set option=<TAB>. Note: With %{bitrate}, you'll have to append the unit yourself, as mentioned in the example below. You can use conditional operator %{?CONDITION?A[?B]}. CONDITION has the same syntax as filters, except for unsupported short and simple expressions and supported keys comparison (e.g. artist=albumartist). Its keys are:
    format strings' special keys
    configuration options
    keyword stream [boolean] (returns true if track is a stream)
    keyword va [boolean] (returns true if track's album is compilation)
Else part can be skipped. A and B can contain string literals in " or '. A and B can be empty. Examples:
    :set format_trackwin= %02n. %t %{?y?(%y)}%= %d
    :set format_current= %n. %-30t %40F (%y)%= %d
    :set format_current= %a - %l%! - %02n. %t%= %{bitrate}Kbps %g %y
    :set format_playlist= %f%= %6{rg_track_gain} dB  %8{rg_track_peak}
    :set format_playlist= %-25%a %-15%l %3n. %t%= %y %d

  Sort Keys
Sort option (lib_sort, pl_sort) value is space separated list of the following sort keys:
    artist, album, title, tracknumber, play_count, discnumber, date, originaldate, genre, comment, albumartist, filename, filemtime, bpm, bitrate, codec, media, codec_profile, rg_track_gain, rg_track_peak, rg_album_gain, rg_album_peak
Note: Adding a '-' in front of the key will reverse the sort order.

PLUGIN OPTIONS
dsp.alsa.device
    PCM device for ALSA plugin, usually "default".
mixer.alsa.channel
    Mixer channel for ALSA Plugin, usually "pcm", "master" or "headphone". To see all possible values run "alsamixer" or "amixer".
mixer.alsa.device
    Mixer device for ALSA plugin, usually "default".
mixer.pulse.restore_volume
    Restore the volume at startup using PulseAudio. Otherwise, cmus sets the volume to 100%, which does not mix well with "flat volumes" feature of PA. Defaults to "1"; set to "0" to turn off.
dsp.ao.buffer_size
    The audio buffer size; defaults to 16kB, but you may want to try bigger values if you experience buffer under-runs.
dsp.ao.device_interface
    Device interface for libao plugin to request a specific playback device/sink/output. This name will be in a format determined by the specific driver backend.
dsp.ao.driver
    Output driver for libao plugin. Example values: "alsa09", "esd", "irix", "oss", "sun", "aixs", "wav".
    Note: of the file output drivers only "wav" is supported.
dsp.ao.wav_counter
    Counter used for making filename. Used only if dsp.ao.driver is "wav". For example if this is 1 and dsp.ao.wav_dir is "/home/user" then PCM data is outputted to "/home/user/01.wav". This counter is incremented every time playback is stopped.
    Note: You probably want to set continue to false (press C), otherwise playback is not stopped between tracks and all PCM data is outputted to one wav file (useful if you want to join files).c Also unsetting shuffle and repeat might be good idea.
dsp.ao.wav_dir
    Output directory for libao plugin; default to the home directory. Used only if dsp.ao.driver is "wav".
dsp.coreaudio.device
    Device for Core Audio output. Leave empty for default.
dsp.coreaudio.enable_hog_mode
    Set hog mode for the device. The default value is false.
dsp.coreaudio.sync_sample_rate
    Synchronize the device sample rate with the player, so no interpolation will be applied to the stream.
dsp.jack.server_name
    Connect to jackd with this name. Leave empty for default.
dsp.jack.resampling_quality
    The re-sampling quality. 0 is low quality but fast, 1 is medium quality, 2 (default) is high quality but more CPU intensive. This option is only available if cmus was compiled with libsamplerate support.
input.cdio.cddb_url
    CDDB URL (default: freedb.freedb.org:8880). Uses HTTP if prefixed with "http://" (e.g.: http://freedb.musicbrainz.org:80/~cddb/cddb.cgi). Set to an empty string to disable CDDB lookup completely.
input.*.priority
    Sets the priority of the input plugin. If multiple plugins can play a file, the plugin with the higher priority is chosen. If the priority is 0, the plugin is disabled.
dsp.oss.device
    PCM device for OSS plugin, usually /dev/dsp.
mixer.oss.channel
    Mixer channel for OSS Plugin, "pcm" or "master".
mixer.oss.device
    Mixer device for OSS plugin, usually /dev/mixer.
dsp.roar.server
    Address of RoarAudio server. Defaults to internal defaults. Can be UNIX, TCP/IP or DECnet address.
dsp.roar.role [music, background_music, ...]
    Role for stream. May be used by the server to apply additional defaults.
dsp.sun.device
    PCM device for Sun plugin, usually /dev/audio.
mixer.sun.channel
    Mixer channel for Sun Plugin, usually "master".
mixer.sun.device
    Mixer device for Sun plugin, usually /dev/mixer.

PLAYING AUDIO DISCS
If the cdio input plugin is enabled, CDs and CD images can be played by setting the device option to a device file (e.g. /dev/cdrom) or an image file (e.g. ~/cd.cue). Then, add a new track using the CDDA URL scheme:
    :add cdda://2
To add the entire disc, use cdda:// (without track number). This only works for audio discs, not images. Adding track ranges is also possible (cdda://1-3). To add images without changing the device option, include the image path in the URL:
    :add cdda:///path/to/cd.cue/2-5
The metadata will be read from CD-Text, and if not available, looked up from a CDDB server (see input.cdio.cddb_url).

FILTERS
Filters are used mostly for filtering contents of library views (1 & 2). Filters do not change the actual library content, i.e. the :save command will still save all tracks to playlist file whether they are visible or not.

  Types
There are three types of filter expressions, each offering more expressiveness:

    simple
        e.g. beatles

    short
        e.g. ~a beatles (!~y1960-1965 | ~d>600)

    long
        e.g. artist="*beatles*"&album="R*"
Simple expressions are only available using live-filter. For other filter commands the type is auto-detected, so both short and long expressions can be used. Long expressions are lists of built-in filters or user defined filters separated with & (and) or | (or). Parenthesises can be used group subexpressions and ! negates result of the expression following it. The same is true for short expressions, but they can only consist of built-in filters. Also, (and)-grouping is done implicitly.

  Strings

long
    filename, artist, albumartist, album, title, genre, comment, codec, codec_profile, media
    Comparators: = and != (not equal)

short
    ~f, ~a, ~A, ~l, ~t, ~g, ~c
    Comparators: none

  Integers

long
    discnumber, tracknumber, date (year), originaldate (year), duration (seconds), bitrate
    Comparators: <, <=, =, >=, >, !=

short
    ~D, ~n, ~y, ~d
    Comparators: <, >
    Ranges: a-b (>=a&<=b), -b (<=b), a- (>=a)

  Booleans
tag (true if track has tags), stream (true if track is a stream)
For short expressions: ~T and ~s

  Defining Filters
Filters can be defined with the fset command. User defined filters appear in the filters view (6). Create a new filter which name is ogg and value filename="*.ogg"
    :fset ogg=filename="*.ogg"
Filter ogg and mp3 files from the 90s. Note the use of user defined filter ogg.
    :fset 90s-ogg-mp3=date>=1990&date<2000&(ogg|filename="*.mp3")

  Activating Filters
factivate changes the visible contents of the library (views 1-2). Activate user defined filters ogg and missing-tags
    :factivate ogg missing-tags
Like above but negate value of ogg filter.
    :factivate !ogg missing-tags
Alternatively, you can filters by pressing space in view 6, then activate them by pressing enter.

  Throw-away Filters
The live-filter and filter commands are useful when you want to use a filter without saving it. It changes the visible contents of the library (views 1-2). filter unactivates all filters in the filters view, while live-filter is applied in addition to all currently activated filters. It persists even after leaving command mode. Filter all rock (anything with rock in genre tag) music from 80s-
    :filter date>=1980&genre="*rock*"
    :filter ~y1980-~grock
Filter all artists/albums/titles containing "sleepwalking"
    :live-filter sleepwalking

  Selecting Tracks Matching a Filter
Mark (select) all tracks with duration less than 2 minutes
    :mark duration<120
Mark (select) all tracks which have been played at least once
    :mark play_count>=1
These commands work in views 2-4.

FILES
cmus reads its configuration from 3 different places in the following order: $XDG_CONFIG_HOME/cmus/autosave
    This file is automatically created and overwritten by cmus on exit, so it should not be modified by hand.
/usr/share/cmus/rc
    This file contains the default configuration.
    If the autosave file did exist, this file is read instead.
$XDG_CONFIG_HOME/cmus/rc
    This file is the static configuration file.
    This file is read immediately after the autosave file, and is never modified by cmus. You can override auto-saved settings in this file. This file is not limited to options; it can contain other commands too.

  Color Schemes
Color schemes (*.theme) are located in /usr/share/cmus or $XDG_CONFIG_HOME/cmus. You can switch them using the :colorscheme command with the basename of the theme file. Note: Colors are not automatically updated when the theme file changes since they are saved in the autosave file.

  Examples
Example status display scripts (see status_display_program) can be found in /usr/share/doc/cmus/examples.

ENVIRONMENT
CMUS_CHARSET
    Override the character set used by cmus (default: `locale charmap`).
CMUS_HOME
    Override the config directory (default: $XDG_CONFIG_HOME/cmus).
CMUS_SOCKET
    Override the socket path (default: $XDG_RUNTIME_DIR/cmus-socket).
HOME
    Full path of the user's home directory.
http_proxy
    URI of the proxy to use for HTTP requests.
USER
    Name of the user running cmus.
USERNAME
    Fallback for USER.

D-Bus Interface (MPRIS)
cmus provides a D-Bus interface following the Media Player Remote Interfacing Specification (MPRIS) v2:
    https://www.freedesktop.org/wiki/Specifications/mpris-spec/
It exposes the /org/mpris/MediaPlayer2 object path with the interfaces org.mpris.MediaPlayer2 and org.mpris.MediaPlayer2.Player. The unique bus name is org.mpris.MediaPlayer2.cmus. Metadata fields follow the naming convention of the specification:
    https://www.freedesktop.org/wiki/Specifications/mpris-spec/metadata/
Additionally, the cmus:stream_title field is exposed if appropriate.

BUGS
The file exists only if you configured cmus with the maximum debug level (./configure DEBUG=2). After a crash, the last lines of ~/cmus-debug.txt may contain useful information. Feature requests and bug reports should go to the GitHub issue tracker:
    https://github.com/cmus/cmus/issues
