This post will guide you how to show a recursive directory listing in a Linux system. How do I display directories recursively on a CentOS or RHEL Linux.
Show Recursive Directory Listing
If you want to list all files under a given directory and its all subdirectories in Linux, and you can use one of the following command:
$ ls -R $ find directory -print $ du -a $ tree directory
For example, you want to get a recursive directory listing for /boot directory, just issuing one of the following command:
$ ls -R /boot
Or
$ sudo find /boot -print
Or
$ du -a /boot
Or
$ tree /boot
Outputs:
devops@devops:~$ ls -R /boot
/boot:
config-5.0.0-25-generic memtest86+.elf
