gdu
Analyze disk space usage
TLDR
Interactively show the disk usage of the current directory
Interactively show the disk usage of a given directory
Interactively show the disk usage of all mounted disks
Interactively show the disk usage of the current directory but ignore some sub-directories
Ignore paths by regex
Ignore hidden directories
Only print the result, do not enter interactive mode
Do not show the progress in non-interactive mode (useful in scripts)
SYNOPSIS
gdu [options] [path]
PARAMETERS
-s, --summarize
Display only the total size of the current directory, similar to 'du -sh'.
-H, --human-readable
Use human-readable sizes (e.g., 1K, 234M, 2G) in non-interactive output.
-L, --dereference
Follow symbolic links during scanning.
-a, --all
Display all files and directories, not just directories or large files.
-m, --no-mouse
Disable mouse support in the interactive user interface.
-c, --no-color
Disable colorized output in the terminal.
-r, --remote-host
Analyze disk usage on a remote host via SSH. Requires SSH access and 'gdu' on the remote.
-x, --one-file-system
Skip directories residing on different filesystems.
-i, --ignore-dirs
Comma-separated list of directory names to ignore during scanning.
-f, --file
Read directory contents from a 'du'-compatible file instead of scanning the disk.
-h, --help
Display the help message and exit.
-v, --version
Print the version information and exit.
DESCRIPTION
gdu (Go Disk Usage) is a modern, blazing-fast, and interactive disk usage analyzer written in Go. It offers an ncurses-like graphical interface for quickly inspecting disk space consumption on Linux/Unix systems.
Designed for efficiency, especially on solid-state drives (SSDs) and filesystems with numerous large directories, gdu leverages parallel processing to scan and report disk usage much quicker than traditional tools like du or even ncdu. Its intuitive interface allows users to easily navigate directory structures, view file and folder sizes, sort entries by various criteria, and even perform direct file or directory deletion operations from within the application, providing a comprehensive and efficient disk management experience.
CAVEATS
Scanning certain system directories (e.g., /root, /proc, /sys) may require sudo or root privileges. The interactive UI requires a compatible terminal emulator. Analyzing remote hosts mandates gdu's presence on the remote system for execution.
INTERACTIVE FEATURES
The gdu interactive UI is highly intuitive. Press h within the application to view a list of keyboard shortcuts for navigation (e.g., j/k for up/down), sorting, showing/hiding percentages (g), and performing actions like deleting files (d) or quitting (q). It provides a real-time, dynamic overview of disk space usage.
PERFORMANCE OPTIMIZATION
gdu is engineered for speed. It utilizes parallel processing to traverse and analyze directories concurrently, significantly reducing scan times compared to single-threaded alternatives. This makes it particularly efficient for large filesystems, network shares, and modern storage devices like SSDs, providing rapid insights into disk consumption.
HISTORY
Developed by Ondřej Dušek (dundee) and written in Go, gdu emerged as a high-performance alternative to existing disk usage analyzers. Its primary motivation was to address the speed limitations of tools like ncdu, especially when dealing with very large filesystems and modern SSDs, by leveraging Go's concurrency features for parallel scanning. It gained popularity for its speed and interactive interface since its initial stable releases around 2019-2020.
