Q applets/ja

QアプレットはCで書かれた小さくて素早い、portageのヘルパーツールです. このガイドは、 パッケージで提供されているこれらヘルパーツールの基本的な使い方を説明します.

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 or.

The complete list of applications that are provided by can be listed 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 (qfile)
The 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 application:

もちろん、インストール後に変更された全てのファイルがここで報告されます. インストール後に手動で編集された設定ファイルが報告されても、心配はありません.

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. Use the  option to show all the DEPEND, RDEPEND , and PDEPEND information for a package.

Listing all packages (installed or not) which depend on some package (qgrep)
The q applets can be used to find ebuilds that mention an ebuild's name ("libechonest" is used in the example below) with great speed:

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

Looking for packages that use some USE flag (quse)

Extracting information from emerge logs (qlop)
There is also a tool that allows to extract useful information from the file. It is called 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.
