如何对指定路径下的所有文件执行for-each循环? [英] How to perform a for-each loop over all the files under a specified path?

问题描述

以下命令尝试枚举当前目录中的所有*.txt文件并对其进行逐一处理:

The following command attempts to enumerate all *.txt files in the current directory and process them one by one:

for line in "find . -iname '*.txt'"; do 
     echo $line
     ls -l $line; 
done

为什么会出现以下错误?

Why do I get the following error?:

ls: invalid option -- 'e'
Try `ls --help' for more information.

推荐答案

这是遍历文件的更好方法，因为它可以处理文件名中的空格和换行符:

Here is a better way to loop over files as it handles spaces and newlines in file names:

find . -type f -iname "*.txt" -print0 | while IFS= read -r -d $'\0' line; do
    echo "$line"
    ls -l "$line"    
done
