'How to create files that should be named like the directories names in Linux?

I want to create files and the names of these files should be like the names of directories in the / directory

I created a shell script like this :

#!/bin/bash

cd /

declare -a array=($(ls -d */));

For i in "${array[@]}"; do
    touch $i
done

But it doesn't do anything when I execute it! Although when I replace the touch with echo, it does print the directories names into the screen. So I think the problem is with the touch command?

Or if there is another way of doing this instead of shell script?

I would recommend using find for this:

  • Search all dirs -type d
  • Limit to 1 folder deep -maxdepth 1
  • Exec a command for each result -exec sh -c ''
  • Remove the trailing slash (/)
  • Run touch
find / -type d -maxdepth 1 -exec sh -c 'echo ${0#/} | xargs touch' '{}' \;

Gives the following folder on my MacOs:

$ ls -ltah
total 0
