attr

brew install attr v2.5.2 GPL-2.0-or-later

C library and command-line tools to get, set, and list extended attributes on filesystem objects.

Why you might care

Extended attributes (xattr) are metadata key-value pairs stored on files and directories; attr provides the low-level interface to read and manipulate them. Essential for build systems, backup tools, and access-control implementations that need to preserve or inspect file metadata beyond standard Unix permissions. Most workflows interact with xattr via higher-level tools, but attr is the foundational library and CLI for direct manipulation.
