历史

项目历史与用法

attr provides command-line tools for manipulating filesystem extended attributes.

项目历史

The official Savannah project and git repository maintain the attr userland utilities, including `attr`, `getfattr`, and `setfattr`, for working with extended attributes on supported filesystems.

采用历史

The supplied package metadata shows attr packaged across Homebrew, Debian, Ubuntu, Fedora, Arch, Alpine, Nix, and openSUSE-style channels, reflecting its role as a small standard systems utility rather than an application framework.

使用方式

Package users install attr for shell access to extended attribute inspection and mutation. The command set is commonly used by administrators, packaging scripts, and filesystem tests that need explicit xattr operations.

为什么软件包爱好者会关心

attr matters to package nerds because it is the user-visible companion to filesystem metadata features that otherwise hide behind kernel and libc interfaces. Its tiny CLI surface makes it a common dependency in system images and test environments.

时间线

2.4.x: Official git refs include late 2.4 series release tags.
2.5.x: Official git refs include 2.5 series release tags.
2.6.0: Official git refs include a v2.6.0 release tag.

Related projects

Filesystem extended attributes are exposed by Linux filesystems and consumed by tools such as backup, security-labeling, and packaging utilities.
The Linux ACL tooling is a nearby low-level filesystem metadata package family.
