Resources

Gentoolkit är en uppsättning av verktyg som underlättar för administreringen av ett Gentoo-system, i synnerhet Portage.

Gentoo är en väldigt unik distribution, med särskilda detaljer som inte finns i andra system. Flera verktyg som utvecklas för att hjälpa med användandet av Gentoo har bidragits, och är grupperade i app-portage/gentoolkit-paketet.

Gentoolkit innehåller verktyg som hjälper användare hantera paket och hålla koll på vad som sker i systemet. De flesta användare - särskilt de som ofta uppdaterar sina system - gynnas av att ha Gentoolkit installerat.

The gentoolkit commands have man pages, type "man <command>" for each command for full documentation.

Installation

USE flags

USE flags for app-portage/gentoolkit Collection of administration scripts for Gentoo

test Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)

Data provided by the Gentoo Package Database · Last update: 2025-03-16 16:59 More information about USE flags

Emerge

Install gentoolkit:

root #emerge --ask app-portage/gentoolkit

eclean

eclean is a tool to remove old source files and old binary packages from the system.

When building and installing packages, the source files are downloaded and preserved in DISTDIR, usually /var/cache/distfiles. This can accumulate several gigabytes of material over time if it is not cleaned periodically. Users should run eclean-dist to clean source files from DISTDIR.

It is possible to create archives of installed packages by using quickpkg or FEATURES="buildpkg". These archived packages are kept in PKGDIR, usually /var/cache/binpkgs. When they are no longer needed, or if they are too old, eclean-pkg can be run to remove them from PKGDIR. It is a good way to ensure that any binary packages on the system are only the latest versions.

For more information on eclean and tips on maintaining a cruft-free system, please read man eclean or check the eclean article.

equery

equery is a tool designed to make asking portage for information easier. Among other operations, it can display package dependencies, metadata, and installed files.

epkginfo

epkginfo is an alias for equery meta command.

eshowkw

eshowkw is an alias for equery keywords command.

eread

eread is a simple utility to display elog files produced by Portage since version 2.1. The saving of elog files can be enabled by setting a couple of variables in /etc/portage/make.conf:

FILE make.confEnabling elog

PORTAGE_ELOG_CLASSES="log"
PORTAGE_ELOG_SYSTEM="save"

Note
This is only one way of saving elog messages. For more information on how Portage's elog system works, please refer to the appropriate page in the Portage Handbook.

Once elog has been set up to satisfaction, run eread to view the log files.

user $eread

This is a list of portage log items. Choose a number to view that file or type
q to quit.
  
1) app-portage:gentoolkit-0.2.4_pre2:20070320-000256.log
2) app-portage:gentoolkit-0.2.4_pre2:20070320-000258.log
3) app-portage:gentoolkit-0.2.4_pre2:20070320-000319.log
4) app-portage:gentoolkit-0.2.3:20070320-000408.log
Choice?

Select a number and the file will be displayed using the paging program specified in the PAGER environment variable. If PAGER is not set, it will use less. The PAGER environmental variable can be set using eselect (module pager).

After displaying the elog item, the user will be prompted to delete the file.

euse

euse provides functionality to set (disable/enable) and obtain information about USE flags in make.conf, without having to edit the file directly.

revdep-rebuild

Important
It is not necessary to run this tool for general use. The portage FEATURE preserve-libs makes the original purpose obsolete. The primary purpose of this tool is now ABI changes for specific libraries when instructions are provided by developers.

This tool is Gentoo's reverse dependency rebuilder. It will scan the installed ebuilds to find packages that have become broken as a result of an upgrade of a package they depend on. It can emerge those packages for users automatically but it can also happen that a given package does not work with the currently installed dependencies, in which case the broken package should be upgraded to a more recent version.

revdep-rebuild will pass flags to emerge which lets the --pretend flag pass through, to see what is going to be emerged again before going any further.

These are the packages that would be merged, in order:

 * Now you can remove -p (or --pretend) from arguments and re-run revdep-rebuild.

To rebuild some packages run revdep-rebuild without the -p flag and the listed packages will be emerged again.
