shell 脚本：我有一个包含几个其他目录的主目录，我想打印这些目录中的所有文件

Question

This script only print files from main directory but doesn't print files of an sub directory that is present in main directory.

If not clear what I mean is if I have a main directory and that main directory has 5 sub directories and all of them contains file. I just want to print all of those files.

read filename
for entry in "$filename"/*
do
  echo "$entry"
done

Answer 1

I just want to print all of those files.

Then use find .

find "$filename" -type f

will print all filenames.

Answer 2

I have to ask: which shell? a Linux shell? Powershell?

If Powershell:

    $files = Get-Childitem -Recurse

Just don't use this starting at just the C:\ .

But with your read and echo , it looks like Linux. have you tried the tree command?
