Q：我在樹莓派命令行模式下使用mplayer播放單首音樂，因為文件名中含有空格，提示不存在該文件，該如何解決？

[johnwick@raspberrypi~]$sudo mplayer Me like yuh.mp3

MPlayer2 2.0-728-g2c378c7-4+b1 (C) 2000-2017 MPlayer Team

Cannot open file '/root/.mplayer/input.conf': No such file or directory

Playing yuh.mp3.

Cannot open file 'yuh.mp3': No such file or directory

Failed to open yuh.mp3.

A：mplayerh播放當前目錄下單首歌曲的格式為： mplayer [文件名]，顯然系統認為 Me like yuh.mp3 是三個獨立文件

解決辦法：①使用引號（英文輸入法下）將文件名全部包含: mplayer "Me like yuh.mp3"

方法②空格前使用連接符號"/"   : mplayer Me/ like/ yuh.mp3     “/”告訴系統后面跟著的字符為原意，不是命令

參考：linux命令行下進入帶空格的文件夾的方法

完畢。
