shell scripting : I have a main directory which contain few other directories and I want to print all files inside those directories

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?
