Linux see directory tree structure using tree command

How do list contents of directories in a structure like format under Linux operating systems?

You need to use command called tree. It will list contents of directories in a tree-like format. It is a recursive directory listing program that produces a depth indented listing of files. When directory arguments are given, tree lists all the files and/or directories found in the given directories each in turn.

Upon completion of listing all files/directories found, tree returns the total number of files and/or directories listed.

tree command installation on a Linux

By default the tree command is not installed. Type the following command to install the same on a RHEL / CentOS / Fedora Linux using yum command:
# yum install tree
## CentOS/RHEL 8.x and Fedora user try the dnf command ##
# dnf install tree

If you are using Debian / Mint / Ubuntu Linux, type the following apt-get command/apt command to install the tree command:
$ sudo apt-get install tree
If you are using Apple OS X/macOS, type brew command:
brew install tree

Syntax – Linux see directory tree structure

The syntax is:

tree /path/to/directory
tree [options]
tree [options] /path/to/directory

To list contents of /etc in a tree-like format:
tree /etc

447 directories, 4331 files

The -a option should be passed to see all files. By default tree does not print hidden files (those beginning with a dot ‘.’). In no event does tree print the file system constructs ‘.’ (current directory) and ‘..’ (previous directory).:
tree -a
To list directories only, run:
tree -d
Pass the -C option to see colorized output, using built-in color defaults:
tree -C
Sample outputs:

    Good tool for easy debugging.

  • Anil Jan 23, 2014 @ 6:29

    it is very usefull for me

  • Osky May 10, 2014 @ 11:09

    I get “âââ” instead of showing the fancy ” |– ”
    I’m using Debian with Swedish character setup…

    • Osky May 10, 2014 @ 11:11

      I fixed it, I just need to add the “–charset X”

      • Osky May 11, 2014 @ 11:07

        Sorry for spamming, but I discovered that if you use PuTTY you can change character setup to UTF-8 and all colors and even åäö works :D

    This one is pretty cool without external packets. ☺

    ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'
    • Pier Mar 4, 2016 @ 14:47

      Oh yes, parsing ls output is so robuste, forking 2 subshells is so quick too !
      tree definitely looks like a good little tool for this purpose.

    • AH Nov 24, 2020 @ 9:56

      Tree is definitely better. It weights 40.7 Ko only.

  • saif Jun 4, 2015 @ 5:44

    Great job

  • Pete Jun 11, 2015 @ 15:32

    Is there a way to have color also enabled?


    • Selim Jun 10, 2016 @ 13:42

      Use option -C

  • Mona Aug 14, 2015 @ 5:12

    How to print files with this??

    ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'
