Q applets/ru

q-апплеты — это набор небольших и быстрых вспомогательных утилит системы Portage, написанных на C. В этом руководстве охватываются некоторые общие применения этих вспомогательных утилит, также известных как пакет app-portage/portage-utils.

Краткая справка
Пакеты устанавливаются как обычно:

Introduction
is a collection of very fast utilities written in C, which are meant to offer a faster but more limited alternative to their  counterparts. Please note that  is not meant to replace. Its utilities are much more efficient than the equivalent ones from  and might be better suited to be used in scripts that need to call Portage repeatedly, but   does not offer the same functionalities. It does not consider eclasses at all and does not provide tools like  and.

More information about  can be found in the Gentoolkit guide.

You can view the complete list of applications in  by typing   or. Please read the man page for each utility described, as this guide is only meant to be a short reference for the most useful functions and does not include all the information about each application.

How to find a package to which a file belongs
finds the package to which a file belongs:

Verifying package integrity
If you want to check MD5 sums or mtimes of the files installed by some package, you can do it using the  application:

Of course, all the files which were changed after installation will be reported here. If the application reports configuration files which you have manually edited after installation, there's nothing to worry about.

Listing packages which depend on some package
Of course there's also an application which allows you to list all the packages which depend on some package. This is done using. Use the  flag to show all the DEPEND, RDEPEND, and PDEPEND information for a package.

Listing files that belong to an ebuild
gives you a list of all files that belong to an ebuild.

Looking for packages that use some USE flag
This is done with, which must be run as root. It may take some time to first create/update the ebuild cache.

Finding package sizes
This is done with  application and is as simple as:

Searching the Portage tree
One of the most powerful tools of  is. This tool allows you to search your Portage tree much faster than default.

Here are some examples of its usage:

I want to thank the guy who made them. What's his homepage?:

I need a jabber client and I need it now:

Extracting information from emerge logs
There is also a tool that allows you to extract useful information from your file. It's called  and it can be useful when you want to estimate package compilation times or compare with your friends whose computer compiles faster. It also allows you to check what's compiling at the moment and how long it will take - which is handy when you're working in the console and don't have any other means to check it.

I'm starting to emerge perl and I want an estimate on how long it usually takes:

Now let's see what's emerging at the moment:
