Can you show/list all extended-attributes and how?

In Linux, independent of filesystem command to view file extended attributes is

getfattr -d -m ".*" <filename> 

At last it show Selinux attributes.

getfattr -d <filename> 

Show only user.* attributes.

On a MacOs the Unix flavor is Darwin which is derived from BSD. In this version of Unix, use the command xattr to list (or create, write, or clear) the extended attributes.

xattr <filename> will just list the names of the attributes

xattr -l <filename> will list their names and values

xattr -h for a more succinct help message

man xattr for a detailed help message (ZZ to exit the help)

I found this command at

getfattr is not present in my debian distribution. I use this instead:

lsattr <filename> 

The command to list all extended attributes is ls -l@.

An example (from my mac, linux/BSD will look different):

felixphew-mbp:/ felixphew$ ls -l@ total 45 drwxrwxr-x+ 63 root admin 2142 27 Dec 17:49 Applications drwxr-xr-x+ 62 root wheel 2108 16 Nov 06:25 Library drwxr-xr-x@ 2 root wheel 68 10 Sep 06:47 Network com.apple.FinderInfo 32 drwxr-xr-x+ 4 root wheel 136 1 Nov 14:02 System drwxr-xr-x 6 root admin 204 28 Dec 07:36 Users drwxrwxrwt@ 3 root admin 102 30 Dec 06:40 Volumes com.apple.FinderInfo 32 drwxr-xr-x@ 39 root wheel 1326 11 Nov 07:06 bin com.apple.FinderInfo 32 drwxrwxr-t@ 2 root admin 68 10 Sep 06:47 cores com.apple.FinderInfo 32 dr-xr-xr-x 3 root wheel 4306 30 Dec 06:40 dev lrwxr-xr-x@ 1 root wheel 11 1 Nov 13:56 etc -> private/etc com.apple.FinderInfo 32 dr-xr-xr-x 2 root wheel 1 30 Dec 06:40 home -rw-r--r--@ 1 root wheel 313 1 Oct 16:12 installer.failurerequests com.apple.FinderInfo 32 dr-xr-xr-x 2 root wheel 1 30 Dec 06:40 net drwxr-xr-x@ 3 root wheel 102 12 Aug 07:19 opt com.apple.FinderInfo 32 drwxr-xr-x@ 6 root wheel 204 1 Nov 14:05 private com.apple.FinderInfo 32 drwxr-xr-x@ 59 root wheel 2006 18 Nov 07:46 sbin com.apple.FinderInfo 32 drwxr-xr-x@ 3 root wheel 102 22 Dec 07:46 srv com.apple.FinderInfo 32 lrwxr-xr-x@ 1 root wheel 11 1 Nov 13:57 tmp -> private/tmp com.apple.FinderInfo 32 drwxr-xr-x@ 13 root wheel 442 23 Nov 11:20 usr com.apple.FinderInfo 32 lrwxr-xr-x@ 1 root wheel 11 1 Nov 13:57 var -> private/var com.apple.FinderInfo 32 

The same dir in ls -l:
