【问题描述】：

我想找到我当前目录中每个文件的绝对路径

现在，当我尝试使用打印出目录中的所有文件时

#!/bin/bash
for x in *; do
        echo $x
done

我得到：

cd
file1
file1.txt
file2.txt
path
readfile
testfile

这是正确的，但是，当我通过将现有代码更改为

#!/bin/bash
for x in *; do
        echo $PATH
done

我得到

重复 7 次（这是目录中存在的文件数）。但是，这看起来根本不像绝对路径，因为输出路径中甚至没有提到文件名。

我应该改变什么才能使这项工作？

【问题讨论】：

$PATH与此无关，并不代表$x的路径。你只是在寻找的完整路径常规文件在当前目录或全部文件（甚至目录/符号链接/套接字），你的意思是直接在当前目录或递归地（例如：在子目录中包含文件）
@Raxi 常规文件的路径，不是全部，我的意思是在当前目录中
