我想在 ubuntu 中使用全局键在 spotify 中更改歌曲。在 Windows 上可以使用键盘上的特殊键“下一首歌曲键”(?) 来实现
我如何重新映射 ubuntu 中的某个键（这里没有“下一首歌曲”按钮）以用作“下一首歌曲”按钮？比如“ctrl +右键”。
我该如何让其与通过 wine 运行的 spotify 一起工作呢？
基本上我想知道“下一首歌曲”按钮的 ASCII 码是什么，以及如何将其映射到 ubuntu 下的组合键。并希望它能够顺利地通过 wine 路由此命令。
编辑：我的 ubuntu 机器上没有“下一首歌曲”按钮。

或者杰邦尼找到了一个使用 dbus-send 的简洁解决方案他的要点如下
或者如果你很着急：
"dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlayPause" XF86AudioPlay
"dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Stop" XF86AudioStop
"dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Next" XF86AudioNext
"dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Previous" XF86AudioPrevious

对于 Ubuntu，现在有一个“Linux 版 Spotify“。要将组合键映射到“下一首歌曲”，dconf-editor 可能会有所帮助（看这里）。一旦完成“下一首歌曲”的键映射，就会出现一个很好的Spotify 包装器用于 John Reese 编写的媒体密钥集成。
编辑：Linux 版 Spotify 现在支持媒体键。

我这样做的方法是使用以下 bash 脚本，它是我使用从其他来源借用的各种命令编写的。您只是要求“playpause”功能，但我认为我最好包括整个功能。您想要的部分是：
#!/bin/bash
# Spotify Launch Script by Ben Kraft
# Borrows some commands from Spotify Control by Tommy Matilla:
# http://sites.google.com/site/tommymattila/home/spotifycontrol
# which itself is based on Stuart Colville's
# http://muffinresearch.co.uk/archives/2009/10/22/ubuntu-lock-screen-and-pause-spotify/
# Requires wmctrl and xvkbd
WP="$HOME/.wine"
SPATH="$HOME/.wine/drive_c/Program Files/Spotify/spotify.exe"
TITLE=$(wmctrl -xl | grep -o -e "spotify\.exe\.Wine.*$" | grep -o -e "Spotify.*$")
ACTIVEWIN=$(wmctrl -va ":ACTIVE:" 2>&1 | grep -o -e "0x.*$")
sendkeys () {
wmctrl -xa "spotify.exe.Wine" || return 1
xvkbd -q -delay 100 -text "$1"
wmctrl -ia $ACTIVEWIN
}
if [ -z $TITLE ] ; then
echo "Spotify is not running!
exit 1
else
sendkeys '\ '
fi
exit 0
简而言之，它用于wmctrl移动到 Spotify 所在的工作区，用于xvkbd向 Spotify 发送空格键击，然后用于wmctrl移回。
要使用它，请将其保存在文件中，将文件标记为可执行（在文件权限对话框中），然后使用 CompizConfig 设置管理器将其添加到命令中。（将其放在bash /path/to/script“命令”选项卡的第一个框中，然后在第二个选项卡中添加键绑定。这可以是您想要使用的任何键。）您将需要wmctrl并xvkbd安装；在 Ubuntu 软件中心搜索它们。
整个脚本如下所示，它提供了一些其他不错的功能，例如转到上一首或下一首曲目以及显示歌曲标题。您可以像使用上面的代码片段一样使用它，只是您必须bash /path/to/script --option在命令框中输入--option脚本中列出的任何内容。

# Usage:
USAGE="
usage: spotify [OPTIONS]
OPTIONS:
--play: Starts Spotify playing if it isn't already
--pause: Pauses Spotify if it isn't already
--playpause: Toggles Spotify between playing and pausing
--prev: Plays the previous song
--next: Plays the next song
--display: Prints the currently playing song and artist to stdout
--notify-send: Use only *after* --display; also pops up a notification with currently playing song and artist
--uri URI: tells Spotify to display URI (e.g. a playlist or user).
With no options, this script will kill a currently running instance of spotify if there is one. With --uri, it starts Spotify iff it isn't running. With any other option, it will return 1 if Spotify is not running.
