Q：我在树莓派命令行模式下使用mplayer播放单首音乐，因为文件名中含有空格，提示不存在该文件，该如何解决？

[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.

Failed to open yuh.mp3.

A：mplayerh播放当前目录下单首歌曲的格式为： mplayer [文件名]，显然系统认为 Me like yuh.mp3 是三个独立文件

解决办法：①使用引号（英文输入法下）将文件名全部包含: mplayer "Me like yuh.mp3"

方法②空格前使用连接符号"\"   : mplayer Me\ like\ yuh.mp3     “\”告诉系统后面跟着的字符为原意，不是命令

参考：linux命令行下进入带空格的文件夹的方法

完毕。
