-.SH REMOTE CONTROL
-.B pianobar
-can be controlled through a fifo. You have to create it yourself by executing
-
- mkfifo ~/.config/pianobar/ctl
-
-Adjust the path if you set up a $XDG_CONFIG_HOME. Afterwards you can write
-commands directly into the fifo. Example (next song):
-
- echo -n 'n' > ~/.config/pianobar/ctl
-
-.B n
-is the keybinding for "next song". If you customized your keybindings you have to use these characters to control
-.B pianobar.
-.I This behaviour may change in the future!
-
-Another example:
-
- while true; do;
- nc -l -p 12345 -s localhost localhost > ~/.config/pianobar/ctl;
- sleep 1;
- done
-
- echo -ne 'n\\x1a' | nc -q 0 127.0.0.1 12345
-
-.SH EVENTCMD
-
-.B pianobar
-can report certain "events" to an external application (see
-.B CONFIGURATION
-). This application is started with the event name as it's first argument. More
-information (artist, title, album, stationName, error code, error description,
-song length in milliseconds, rating, album art url) is supplied through stdin.
-
-Currently supported events are: artistbookmark, songban, songbookmark,
-songexplain, songfinish, songlove, songmove, songshelf, songstart,
-stationaddmusic, stationaddshared, stationcreate, stationdelete,
-stationfetchplaylist, stationquickmixtoggle, stationrename
-
-An example script can be found in the contrib/ directory of
-.B pianobar's
-source distribution.
