Installation

From sources

To build the uc from scratch, make sure you have a working Go 1.24+ (instructions), then:

go install github.com/essentialkaos/uc@latest

From ESSENTIAL KAOS Public Repository

sudo dnf install -y https://pkgs.kaos.st/kaos-repo-latest.el$(grep 'CPE_NAME' /etc/os-release | tr -d '"' | cut -d':' -f5).noarch.rpm
sudo dnf install uc

Prebuilt binaries

You can download prebuilt binaries for Linux from EK Apps Repository.

To install the latest prebuilt version, do:

bash <(curl -fsSL https://apps.kaos.st/get) uc

Upgrading

Since version 3.1.0 you can update uc to the latest release using self-update feature:

uc --update

This command will runs a self-update in interactive mode. If you want to run a quiet update (no output), use the following command:

uc --update=quiet

Note

Please note that the self-update feature only works with binaries that are downloaded from the EK Apps Repository. Binaries from packages do not have a self-update feature and must be upgraded via the package manager.

Command-line completion

You can generate completion for bash, zsh or fish shell.

Bash:

uc --completion=bash | sudo tee /etc/bash_completion.d/uc > /dev/null

ZSH:

uc --completion=zsh | sudo tee /usr/share/zsh/site-functions/uc > /dev/null

Fish:

uc --completion=fish | sudo tee /usr/share/fish/vendor_completions.d/uc.fish > /dev/null
