将文件从一个子目录移动到另一个子目录

Question

我尝试将文件从一个目录移动到另一个目录，但没有成功。所以我搜索并找到了一个适合我想要的答案。当我运行它，修改到我的目录时，它给出了

想做什么：

${filename,,*}: 替换错误！

这是我用的：

for filename in *; do
  case "${filename,,*}" in
    b01.nii*)    mv "$filename" "$/Users/dave/Desktop/test/untitled_folder_*/str" ;;
    vol_01.nii*) mv "$filename" "$/Users/dave/Desktop/test/untitled_folder_*/rs" ;;
    *)           echo "don't know where to put $filename";;
  esac
done

谢谢

Answer 1

你两个错误：

主要问题是 for 命令，变量$filename 包含* 而不是真实的文件名。你应该使用$(find . -name "*");do中的文件名

第二个是这样的：

您必须确定 $filename 变量的值，即在我的 bash shell 中，文件名输出是

./b01.nii 
./vol_01.nii 

在./b01.nii* )的情况下最好使用下面的语法

我已将您的 mv 替换为 echo 只是为了测试脚本：

for filename in $(find . -name "*"); do

  case ${filename} in
    ./b01.nii* )    
                echo "$filename ${filename}/Users/dave/Desktop/test/untitled_folder_*/str" ;;
    ./vol_01.nii* ) 
                echo "$filename ${filename}/Users/dave/Desktop/test/untitled_folder_*/rs" ;;
    *)          
                echo "don't know where to put $filename";;
  esac
done

我的输出是
