问题
So basically, I have a folder with a bunch of subfolders all with over 100 files in them. I want to take all of the mp3 files (really generic extension since I'll have to do this with jpg, etc.) and move them to a new folder in the original directory. So basically the file structure looks like this:
/.../dir/recup1/file1.mp3
/.../dir/recup2/file2.mp3
... etc.
and I want it to look like this:
/.../dir/music/file1.mp3
/.../dir/music/file2.mp3
... etc.
I figured I would use a bash script that looked along these lines:
#!/bin/bash
STR=`find ./ -type f -name \*.mp3`
FILES=(echo $STR | tr ".mp3 " "\n")
for x in $FILES
do
echo "> [$x]"
done
I just have it echo for now, but eventually I would want to use mv to get it to the correct folder. Obviously this doesn't work though because tr sees each character as a delimiter, so if you guys have a better idea I'd appreciate it.
(FYI, I'm running netbook Ubuntu, so if there's a GUI way akin to Windows' search, I would not be against using it)
回答1:
If the music folder exists then the following should work -
find /path/to/search -type f -iname "*.mp3" -exec mv {} path/to/music \;
A -exec command must be terminated with a ; (so you usually need to type \; or ';' to avoid interpretion by the shell) or a +. The difference is that with ;, the command is called once per file, with +, it is called just as few times as possible (usually once, but there is a maximum length for a command line, so it might be split up) with all filenames.

You can do it like this:
find /some/dir -type f -iname '*.mp3' -exec mv \{\} /where/to/move/ \;
The \{\} part will be replaced by the found file name/path. The \; part sets the end for the -exec part, it can't be left out.
If you want to print what was found, just add a -print flag like:
find /some/dir -type f -iname '*.mp3' -print -exec mv \{\} /where/to/move/ \;
