Question

我在获取bash脚本来打印文件的修改日期时遇到了一些麻烦，这是我的代码：

files=$(ls -R)    

for file in ${files}
do
  modification=$(date +%D -r ${file})
    echo ${modification}
done

问题是，当我运行脚本时，与脚本处于同一级别的所有内容都将打印其日期，但是如果文件低于或高于该级别，则会收到错误，如以下输出所示：

File .: was modified on 
File 1.txt was modified on 02/05/19
File 2.txt was modified on 02/05/19
File 3.txt was modified on 02/05/19
File folder was modified on 02/05/19
File GetFiles.sh was modified on 02/05/19
date: ./folder:: No such file or directory
File ./folder: was modified on 
date: folder1.txt: No such file or directory
File folder1.txt was modified on 
date: folder2.txt: No such file or directory
File folder2.txt was modified on 
date: folder3.txt: No such file or directory
File folder3.txt was modified on

Answer 1

shopt -s globstar
for i in **; do date +"$i was modified on %D" -r "$i"; done

来自man bash：

globstar：如果设置，则在路径名扩展上下文中使用的模式**将匹配所有文件，并且零或更多目录和子目录。如果模式后跟/，则仅目录和子目录匹配。
