Gentoo

Gentoo Linux uses a unique package management system called Portage for handling software installation, updates, and removal.

Portage Basics

Portage is a source-based package management system for Gentoo. It compiles packages from source code on your system, allowing for customization and optimization.

Update Portage Tree

To ensure you have the latest package information, update the Portage tree:

sudo emerge --sync

Install Packages

To install a package, use the emerge command followed by the package name:

sudo emerge [package_name]

Remove Packages

To remove a package:

sudo emerge --unmerge [package_name]

Update Packages

To update all installed packages:

sudo emerge --update --deep --with-bdeps=y --newuse @world

Search for Packages

To search for packages by name:

eix [search_term]

Show Package Information

To display detailed information about a package:

equery show [package_name]

Additional Portage Commands

Local Use Flags

Use flags are options that allow you to customize the features and dependencies of packages. You can manage local use flags by editing /etc/portage/package.use and /etc/portage/package.mask.

Cleaning

To clean package build files:

sudo eclean-dist

Keeping Your System Updated

Regularly update your system to ensure security and stability:

sudo emerge --sync sudo emerge --update --deep --with-bdeps=y --newuse @world

These commands should help you manage packages efficiently on your Gentoo system. Remember to use sudo to execute commands as a superuser when required.
