Those are not technically extended attributes.  getxattr(2) and friends don't return them.  They are inode flags, queried/set by ioctl_iflags(2) on Linux.

BSD find uses -flags for something similar.  I think GNU find should also use -flags for inode flags on Linux.  It could use the same syntax as chattr(1), much like how -perm uses the same syntax as chmod(1).

On BSD it should use st_flags and strtofflags(3) to be compatible with the system find(1).

bug #49574 is a duplicate of this bug (though that one predates this one).

Until this functionality is included in GNU find, you could use my "rawhide" program which can search by extended attributes (EA) (names and/or contents) and also by the contents of access control lists (ACL). It's available from https://raf.org/rawhide as well as https://codeberg.org/raforg/rawhide.

As mentioned in a post to the bug-findutils mailing list, Morgan Weetman graciously made available his previous work implementing -xattr (and -cap for capabilities) in https://gitlab.com/mweetman/findutils .  This should make an excellent starting place for future work.  See Pavel Raiskup's feedback and Bernhard Voelker's feedback for remaining issues.

[Note: This is being added as a comment to the bug tracker for others who may find this issue there.]

It would be great if find could support searching for files based on the presence/absence of extended attributes (xattrs).

The only way I could find to do this currently is via -exec, as suggested in https://unix.stackexchange.com/q/162359 and https://unix.stackexchange.com/q/132795

For reference, OS X find supports xattr search with the tests:

-xattr
True if the file has any extended attributes.

-xattrname name
True if the file has an extended attribute with the specified name.

per https://opensource.apple.com/source/shell_cmds/shell_cmds-203/find/find.1.auto.html

Thanks for considering,
Kevin
