我搜索了很多关于如何在工作时通过终端播放音乐，并时不时地进行基本的音乐控制，例如快进、快退、下一首、上一首、播放/暂停、停止和退出。但一无所获。我遇到了 SoX，但没有得到任何帮助。后来在 mplayer 手册页中，我发现了很多 cmd_line 选项。
在那里我发现-ss（按秒搜索），-sb（按字节查找），-结束位置（在指定时间后停止）。
我想知道，
- 如何使用这些选项。因为一旦我使用以下方式播放曲目：mplayer 音轨.扩展名终端正在显示剧情细节。
再次，
您能否建议后退、下一个、上一个等选项？
您能否建议任何其他可轻松实现基本音乐播放控制的替代方案？
我如何播放文件并同时在终端中工作？

基本导航：
你在追求这些基本的MPlayer 的导航键，这些键将在播放剪辑时操作：
Basic keys: (complete list in the man page, also check input.conf)
<- or -> seek backward/forward 10 seconds
down or up seek backward/forward 1 minute
pgdown or pgup seek backward/forward 10 minutes
< or > step backward/forward in playlist
p or SPACE pause movie (press any key to continue)
q or ESC stop playing and quit program
+ or - adjust audio delay by +/- 0.1 second
o cycle OSD mode: none / seekbar / seekbar + timer
* or / increase or decrease PCM volume
x or z adjust subtitle delay by +/- 0.1 second
r or t adjust subtitle position up/down, also see -vf expand
mplayer当然，这些可以在手册页中看到，但这里演示的少量选择是从在终端窗口中运行命令所显示的列表中获取的。
复杂的导航和控制：
如果你追求更多复杂的input.conf控制您可以在目录中创建文件$HOME/.mplayer并在该文件中放置以下详细信息：
##
## MPlayer input control file
##
## You are able to redefine default keyboard/joystick/mouse/LIRC bindings, or
## add new ones here.
## See DOCS/tech/slave.txt for possible commands that can be bound.
## Also see mplayer -input cmdlist for other possible options.
## The file should be placed in the $HOME/.mplayer directory.
##
## If you wish to unbind a key, use key ignore.
## e.g. ENTER ignore

## OSD Menu movement keys

## If you are using only the keyboard it is enough to define one command (like
## "menu up"), because then that single key will display the menu, which can
## then be navigated with the cursor keys and ENTER (defined in menu.conf).
##
## LIRC users should bind each "menu" command to a button on their remote.
##
## The set_menu command directly displays the (sub)menu specified as
## its argument. Usage should be self-explanatory (although not likely
## to be needed), after reading input.conf.

您可以花尽可能多的时间来调整这些选项:)
做点别的事：
至于在播放剪辑时工作：我自己的做法是打开一个新的终端窗口，但另一个选择是在现有的终端窗口中打开另一个选项卡（如果支持的话）。
