XBindKeys is a program that allows you to launch shell commands with your keyboard or your mouse under the X Window System. It links commands to keys or mouse buttons, using a configuration file. It's independent of the window manager and can capture all keyboard keys (ex: Power, Wake...). It optionally supports a Guile-based configuration file layout, which enables you to access all XBindKeys internals, so you can have key combinations, double clicks or timed double clicks take actions. Also all functions that work in Guile will work for XBindKeys.

The FSQA regression test suite, more commonly known as xfstests, comprises over 1,500 tests that exercise (torture) both the user- and kernel-space parts of many different file systems.

As the package's name subtly implies, it was originally developed to test the XFS file system. Today, xfstests is the primary test suite for all major file systems supported by the kernel Linux including XFS, ext4, and Btrfs, but also virtual and network file systems such as NFS, 9P, and the overlay file system.

The packaged check script is not in PATH but can be invoked with the included xfstests-check helper.
