Gentoolkit是一套简化Gentoo系统管理的工具。本文档介绍了Gentoolkit中的一些工具的基础知识。

Gentoo是一款独特的发行版,它呈现了一些对于其他发行版根本不存在的复杂性。由于Gentoo开发人员和贡献者发现了其中的一些复杂性,他们还编写了一些工具来帮助用户和管理员解决这些问题。许多工具已经贡献给Gentoo项目,并包含在app-portage/gentoolkit包中。

Gentoolkit包含大量有用的工具,可帮助用户管理包并跟踪系统中发生的情况。 大多数用户(特别是经常更新系统的用户)将从安装Gentoolkit中受益。

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

安装

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)

Emerge

Install gentoolkit:

root #emerge --ask app-portage/gentoolkit

eclean

eclean是一个从系统中删除旧源文件和旧二进制包的工具。

构建和安装包时,源文件将下载并保存在 DISTDIR 中,通常是 /var/cache/distfiles。如果不定期清洁,这可能会累积数千兆字节的材料。用户应该运行 eclean-dist 来清理 DISTDIR 中的源文件。

可以使用 quickpkgFEATURES="buildpkg" 创建已安装软件包的存档。这些存档的包保存在 PKGDIR 中,通常是 /var/cache/binpkgs。当它们不再需要时,或者它们太旧时,可以运行 eclean-pkg 将它们从 PKGDIR 中移除,这是确保系统上的任何二进制包只是最新版本的好方法。

有关eclean的更多信息以及维护无残留系统的提示,请阅读man eclean或查看eclean文章。

epkginfo

epkginfo is a tool used to display package metadata information. It is a shortcut to using the equery meta command.

equery

equery is a tool to make several common Portage operations simpler. Among other operations, it can display package dependencies, metadata, and installed files.

eread

eread是一个简单的工具,用于显示自2.1版以来Portage生成的elog文件,可以通过在/etc/portage/make.conf中设置几个变量来启用elog文件的保存:

文件 make.conf启用elog
PORTAGE_ELOG_CLASSES="log"
PORTAGE_ELOG_SYSTEM="save"
附注
这只是保存elog消息的一种方法。 有关Portage elog系统如何工作的更多信息,请参阅Portage手册中的相应页面。

一旦elog设置满意,运行eread查看日志文件。

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?

选择一个数字,将使用PAGER环境变量中指定的分页程序显示该文件。如果没有设置PAGER,将使用less。可以使用eselectpager模块)设置PAGER环境变量。

显示elog项目后,系统将提示您是否要删除该文件。

eshowkw

Display keywords for specified package or for package that is in pwd.

To show keywords for a specific package, indicate that package on the command line, for example:

root #eshowkw gentoo-sources
Keywords for sys-kernel/gentoo-sources:
          |                               |   u          |

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

重要
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.

这个工具是Gentoo的反向依赖重建器,它将扫描已安装的ebuild,以查找因其所依赖的软件包升级而损坏的软件包。它可以自动为用户安装这些包,但也可能发生给定包不能与当前安装的依赖项一起使用,在这种情况下,您应该将损坏的包升级到更新的版本。revdep-rebuild会将标志传递给emerge,它允许你使用--pretend标志来查看将要再次出现的内容。

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:
  
Calculating dependencies... done!
[ebuild   R   ] media-plugins/gst-plugins-taglib-0.10.17
[ebuild   R   ] x11-libs/gtkglext-1.2.0

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

要重建某些软件包,请运行revdep-rebuild而不使用-p标志,列表中的包将会被安装。

root #revdep-rebuild
