牛刀小试--删除多余的lrc文件

在复制mp3的歌词文件的时候，多复制了许多，用手动删除那些多余的文件很麻烦，也很慢，就写了一个脚本

#!/bin/bash
ls -l *.lrc | cut -b 46- | awk -F '.lrc' '{print $1}' > file0
ls -l *.mp3 | cut -b 51- > file1
ls -l *.wma | cut -b 49- > file2
while read -r line
    do
        name1=$line".mp3"
        name2=$line".wma"
        while read -r line1
            do
                if [ "$name1" = "$line1" ]
                    then
                        echo $name1
                    else
                        if [ -f "$name1" ] ; then
                            rm $name1
                            echo "$name1 rm"
                        fi
                fi
        done < file1
        while read -r line2
            do
                if [ "$name2" = "$line2" ]
                    then
                        echo $name2
                    else
                        if [ -f "$name2" ] ; then
                            rm $name2
                            echo "$name2 rm"
                        fi
                fi
        done < file2
done < file0
rm file0
rm file1
rm file2

具体的实现可能还有一些小问题，没有考虑周全。
