In this article we will look at the gdu program. It is an analyzer of the used disk space and is open source.
The gdu tool is designed for SSDs where parallel processing can be used. This tool can also work with HDDs with lower performance compared to SSDs. You can also check the results of the benchmark. There are many other similar tools and you must first play with gdu to see if it meets your needs.
How to install
# Using curl: curl -L https://github.com/dundee/gdu/releases/latest/download/gdu_linux_amd64.tgz | tar xz chmod +x gdu_linux_amd64 mv gdu_linux_amd64 /usr/bin/gduCode language: PHP (php)
# Arch Linux: yay -S gduCode language: PHP (php)
# Debian: dpkg -i gdu_*_amd64.debCode language: CSS (css)
# Ubuntu add-apt-repository ppa:daniel-milde/gdu apt-get update apt-get install gduCode language: PHP (php)
# NixOS: nix-env -iA nixos.gduCode language: CSS (css)
# Homebrew: brew install -f gdu brew link --overwrite gdu # if you have coreutils installed as wellCode language: PHP (php)
# Snap: snap install gdu-disk-usage-analyzer snap connect gdu-disk-usage-analyzer:mount-observe :mount-observe snap connect gdu-disk-usage-analyzer:system-backup :system-backup snap alias gdu-disk-usage-analyzer.gdu gduCode language: CSS (css)
# Binenv: binenv install gduCode language: PHP (php)
# Go: go get -u github.com/dundee/gdu/v4Code language: PHP (php)
Now you can verify the installation by running the following command.
# Check Version gdu --versionCode language: PHP (php)
If you run the gdu command without an argument, it will scan your current working directory. I am now in my home directory and when I start gdu, you can see from the image below that my home directory is being scanned.
# Examples gdu # analyze current dir gdu -a # show apparent size instead of disk usage gdu <some_dir_to_analyze> # analyze given dir gdu -d # show all mounted disks gdu -l ./gdu.log <some_dir> # write errors to log file gdu -i /sys,/proc / # ignore some paths gdu -c / # use only white/gray/black colors gdu -n / # only print stats, do not start interactive mode gdu -np / # do not show progress, useful when using its output in a script gdu / > file # write stats to file, do not start interactive modeCode language: PHP (php)
