tree
command provides a clear, tree-like representation of directories and files.The tree
command in Linux is a versatile utility that displays the contents of directories in a visually appealing tree-like format. This command is especially useful for developers, system administrators, and users who need a clear overview of the file system hierarchy without navigating through each directory manually.
While many Linux distributions come with the tree
command pre-installed, some may require manual installation. Here’s how you can install tree
on various platforms:
sudo apt-get update
sudo apt-get install tree
sudo yum install tree -y
brew install tree
After installation, you can verify the installation by running:
tree --version
The basic syntax for the tree
command is:
tree [options] [directory]
If no directory is specified, tree
defaults to the current working directory.
The tree
command offers a plethora of options to customize the output according to user requirements. Below are some of the most commonly used options:
By default, tree
does not display hidden files (those starting with a dot). Using the -a
option includes these hidden files in the output.
tree -a
The -d
option limits the output to directories, excluding all files. This is useful for getting a quick overview of the directory structure.
tree -d
Using the -f
option prepends the full path to each file and directory, providing a complete path structure.
tree -f
The -L
option restricts the display to a specified number of directory levels. For example, -L 2
limits the output to two levels deep.
tree -L 2
The -P
option allows users to display only files and directories that match a specific pattern. Wildcards are supported.
tree -P "*.txt"
Conversely, the -I
option excludes files and directories that match the given pattern.
tree -I "*.log"
The -C
option adds color to the output, making it easier to distinguish between different file types and directories.
tree -C
-s
: Display the size of each file.-u
: Show the owner of each file and directory.-g
: Show the group ownership of each file and directory.-t
: Sort the output based on modification time.To display the tree structure of the current directory:
tree
To include hidden files in the display:
tree -a
To display only directories without listing the files:
tree -d
To limit the display to two levels of depth:
tree -L 2
To display only files with a .txt extension:
tree -P "*.txt"
To exclude the .git
directory from the display:
tree -I ".git"
To display the full path for each file and directory:
tree -f
To colorize the output for better readability:
tree -C
You can combine multiple options to customize the output further. For example, to display directories only, include hidden directories, and limit the depth to three levels:
tree -adL 3
To save the output of the tree
command to a file for later reference:
tree -a > directory_structure.txt
The tree
command is particularly useful for generating documentation of project structures, allowing team members to quickly understand the layout of a project.
You can pipe the output of the tree
command to other tools for further processing. For example, to search for a specific directory within the tree:
tree | grep "src"
The output of the tree
command represents the directory hierarchy in a tree-like format. Each level of indentation indicates a deeper level in the directory structure.
If the -C
option is used, different colors are applied to files and directories for easy differentiation:
Color | Represents |
---|---|
Green | Executable Files |
Blue | Directories |
Cyan | Symbolic Links |
Yellow | Device Files |
Yes, you can use the tree
command on remote servers via SSH. Ensure that the tree
utility is installed on the remote server.
Use the -a
option to include hidden files (those starting with a dot) in the output:
tree -a
While tree
is widely available across various Linux distributions, it might not be installed by default on some. Refer to the installation section to install it using your distribution’s package manager.
You can exclude multiple patterns by separating them with the |
character. For example, to exclude both .git
and node_modules
directories:
tree -I ".git|node_modules"
The tree
command is an indispensable tool for anyone looking to gain a clear and structured view of their file system. Its ability to display directories and files in a hierarchical format, combined with numerous customization options, makes it a powerful utility for managing and documenting directory structures. Whether you are a developer organizing project files or a system administrator overseeing system directories, mastering the tree
command can significantly enhance your workflow and efficiency.
