history
Project history and usage
attr provides command-line tools for manipulating filesystem extended attributes.
Project history
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.
Adoption history
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.
How it is used
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.
Why package nerds care
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.
