linux命令行下文件名中有空格的处理方法
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? $sudo mplayer Me like yuh.mp3 MPlayer2 2.0-728-g2c378c7-4+b1 (C) 2000-2017 MPlayer Team Cannot open file /root/.mplayer/input.conQ：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?

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
完毕。
