linux - MV 命令给我的是相同的文件错误

Question

所以我正在构建这个脚本以从“垃圾”目录中获取一个文件并将其移动到主目录。我收到错误 mv:/home/user/Trash/和/home/user/Trash 是同一个文件。问题是我正在将文件移动到/home/user。我不明白为什么它会给我这个错误。

脚本:

trash="/home/user/Trash"
homedirectory="/home/user/"
for files in "$trash"/*
do
echo "$(basename $files) deleted on $(date -r $files)"
done
echo "Enter the filename to undelete from the above list:"
read $undeletefile
mv $trash/$undeletefile $homedirectory

输出:

myfile2 deleted on Thu Jan 23 18:47:50 CST 2014
trashfile deleted on Fri Feb 28 23:07:33 CST 2014
Enter the filename to undelete from the above list:
trashfile
mv: `/home/user/Trash/' and `/home/user/Trash' are the same file

Answer 1

我认为您的问题出在read 命令中。您不应该向其中添加 $ 。尝试:

read undeletefile
