循环浏览给定目录中的文件 [英] Loop through files in a given directory

问题描述

我试图遍历用户指定目录中的每个文件. 这是我的代码:

I am trying to loop through every file in a user specified directory. Here's my code:

clear
echo "enter the directory path: \n"
read directory
for file in $directory; do
    echo $file
done

我的输入，例如:/home/user/Downloads

我得到的输出:/home/user/Downloads

如果我使用

clear
for file in *; do
    echo $file
done

可以，但是只显示当前目录的内容

It works, but it shows only the contenets of current directory

推荐答案

如果只希望非递归地将文件放在当前目录中，请结合使用:

If you only want the files non-recursively in the current directory, combine what you have:

read -p 'Enter the directory path: ' directory
for file in "$directory"/*; do
  echo "$file"
done

如果您想递归循环并且拥有bash 4，那就不难了:

If you want to loop recursively and you have bash 4, it's not much harder:

shopt -s globstar
for file in "$directory"/**/*; do …

但是，如果您只使用bash 3，则最好使用find.

But if you only have bash 3, you'd be better off using find.

find "$directory"
