Q：我在樹莓派命令行模式下使用mplayer播放單首音樂，因?yàn)槲募泻锌崭?，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

Playing yuh.mp3.

A：mplayerh播放當(dāng)前目錄下單首歌曲的格式為： mplayer [文件名]，顯然系統(tǒng)認(rèn)為 Me like yuh.mp3 是三個(gè)獨(dú)立文件

解決辦法：①使用引號(hào)（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(hào)"\&;   : mplayer Me\ like\ yuh.mp3     “\&;告訴系統(tǒng)后面跟著的字符為原意，不是命令

參考：linux命令行下進(jìn)入帶空格的文件夾的方法

完畢。
