Extended file attributes allow extra metadata to be added to files and directories. $ xattr -d pl.psionides macruby-interview.html $ xattr -w pl.psionides foo macruby-interview.html It can print file’s metadata attributes and their values, modify attributes and remove them, like this: $ xattr macruby-interview.htmlĬom.apple.quarantine: 0000 485e5e65 Firefox | There is a command line utility for accessing and managing that metadata, named xattr.
