文件对比Shell 求更好方案

Question

differ=$(diff -rq $1 $2| awk {'print $2,$3,$4'} );
for file in $differ

do
    echo $file
done

$file 输出如下

/home/test/system/app.text
and
/home/vgg/system/app.text

/home/test/system/app1.text
and
/home/vgg/system/app2.text

in
/home/test/system:
app.txt

我想让其

vimdiff 旧文件 新文件

确认无误后

cp /home/test/system/app.txt /home/vgg/system/app.txt

如果是只是单独的某个文件有的话 in ...

cp /home/test/system/app.txt /home/vgg/system/app.txt
