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, которые находятся в пакете.

The package 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 q applets are not meant to replace gentoolkit. The utilities may be much more efficient than the equivalent ones from gentoolkit and might be better suited to be used in scripts that need to call Portage repeatedly, but they do not offer the same functionality. q applets do not consider eclasses and do not provide tools like revdep-rebuild or glsa-check.

Configuration
Before using the applets first initialize the cache:

Invocation
The complete list of applications that are provided by can be listed by typing man q or q --help. 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.

To see the available applets with a short description of their function, use q --help :

How to find a package to which a file belongs (qfile)
The qfile command finds the package to which a file belongs:

Verifying package integrity (qcheck)
To check the MD5 sums or modification times of the files installed by some package, use the qcheck application:

Здесь будет сообщено обо всех файлах, измененных после установки. Если приложение сообщает о файлах конфигурации, отредактированных вручную после установки, то не о чем беспокоиться.

Listing packages which depend on some package (qdepends)
Of course there's also an application which allows to list all the packages which depend on some package. This is done using qdepends. Use the  option to show all the ,  , and   information for a package.

Listing files that belong to an ebuild (qlist)
The qlist command gives a list of all files that belong to an ebuild.

Looking for packages that use some USE flag (quse)
Listing used USE flags is done with quse, which must be run with root permissions. It may take some time to first create/update the ebuild cache.

Finding package sizes (qsize)
To show the size of a package, use the qsize application:

Searching the Portage tree (qsearch)
One of the most powerful tools of is qsearch</tt>. This tool allows to search the Portage tree much faster than using the emerge -s</tt> command.

Ниже приведено несколько примеров его использования:

The homepage of packages can be queried using the  option:

Extracting information from emerge logs (qlop)
There is also a tool that allows to extract useful information from the file. It is called qlop</tt> and it can be useful when package compilation times need to be estimated or to compare build times with other systems. It also allows to check what's compiling at the moment and how long it will probably take - which is handy when working in the console and don't have any other means to check it.
