我编写了一个脚本，将某些文件从一个文件夹移动到另一个文件夹，但是出现以下错误，我检查了2个文件夹，并注意到1个文件夹中有此类文件，而另一个则没有此类文件，但是为什么它们都显示“ mv”无法统计没有此类文件或目录”

脚本是：
list=`ls dest_folder`
cd dest_folder
cwd=`pwd`
for folder in $list;do
mv ${cwd}/${folder}'/data/*' ${cwd}/${folder}
done
我跑了进去/home/esolve/project/capture/tcp_50x50/。
mv ${cwd}/${folder}'/data/*' ${cwd}/${folder}
'那里的双引号（）防止外壳程序进行globbing。将*被逐字传递给mv命令，因为它没有找到文件名为从而未能*在指定的目录中。
更改为：
mv "${cwd}/${folder}/data"/* "${cwd}/${folder}"
（如果目录名中带有空格，则双引号可以防止出现问题*。）。
不过，您仍然会得到有关空目录的错误。（类似的原因：如果文件找不到与模式匹配的文件，则它将模式本身作为参数传递给命令。）
