A simple mv command in a BASH script
提问by user3167628
The aim of my script:
我的脚本的目的：
- look at all the files in a directory ($Home/Music/TEST) and its sub-directories (they are music files)
- find out what music genreeach file belongs to
- if the genre is Heavy, then move the file to another directory ($Home/Music/Output)
- 查看目录 ($Home/Music/TEST) 及其子目录中的所有文件（它们是音乐文件）
- 找出每个文件属于什么音乐流派
- 如果类型为Heavy，则将文件移动到另一个目录 ($Home/Music/Output)
This is what I have:
这就是我所拥有的：
#!/bin/bash
cd Music/TEST
for files in *
do
if [ -f "$files" ];then
# use mminfo to get the track info
genre=`mminfo "$files"|grep genre|awk -F: '{print }'|sed 's/^ *//g'|sed 's/[^a-zA-Z0-9\ \-\_]//g'`
if [ $genre = Heavy ] ;then
mv "$files" "~/Music/Output/$files"
fi
fi
done
Please tell me how to write the mv command. Everything I have tried has failed. I get errors like this:
请告诉我如何编写 mv 命令。我尝试过的一切都失败了。我收到这样的错误：
mv: cannot move ‘3rd Eye Landslide.mp3' to ‘/Music/Output/3rd Eye Landslide.mp3': No such file or directory
mv：无法将“3rd Eye Landslide.mp3”移动到“/Music/Output/3rd Eye Landslide.mp3”：没有这样的文件或目录
Please don't think I wrote that mminfo line - that's just copied from good old Google search. It's way beyond me.
请不要以为我写了那行 mminfo - 那是从旧的 Google 搜索中复制的。它远远超出了我。

Your second argument to mvappears to be "~/Music/Output/$files"
你的第二个论点mv似乎是"~/Music/Output/$files"
If the ~is meant to signify your home directory, you should use $HOMEinstead, like:
如果~用于表示您的主目录，则应$HOME改用，例如：
mv "$files" "$HOME/Music/Output/$files"
~does not expand to $HOMEwhen quoted.
~$HOME引用时不会扩展到。

By the look of it the problem occurs when you move the file to its destination.Please check that /Music/Output/ exits from your current directory.Alternatively use the absolute path to make it safe. Also it's a good idea not use space in the file-name.Hope this will helps.:)
从外观上看，当您将文件移动到目标位置时会出现问题。请检查 /Music/Output/ 是否从当前目录中退出。或者使用绝对路径以确保安全。另外，最好不要在文件名中使用空格。希望这会有所帮助。:)

Put this command before mv command should fix your problem.
将此命令放在 mv 命令之前应该可以解决您的问题。
mkdir -p ~/Music/Output
