Most GNU utils are already there but GNU stat is unfortunately not part of them. Solaris ls has been extended to support some GNU options though, and they provide the information required.

I have not come across ls -lu before; I have tried repeatedly catting the file atimetest.txt today, but that does not show any change in the ls -lu output.
I am happy to accept that the default setting for atime (=on) updates the inode data, which is something I cannot see easily, in my current setup.

Here is a test showing the access time changing on Solaris 11.2:

Code:

$ ls -l foo
-rw-r-----   1 jlliagre staff          5 Mar 20 01:20 foo
$ ls -l --full-time foo
-rw-r-----   1 jlliagre staff          5 2015-03-20 01:20:15.576863674 +0100 foo
$ ls -lu --full-time foo
-rw-r-----   1 jlliagre staff          5 2015-04-25 08:52:32.741753870 +0200 foo
$ cat foo > /dev/null
$ ls -lu --full-time foo
-rw-r-----   1 jlliagre staff          5 2015-09-10 14:59:57.582793533 +0200 foo

mtime, ctime, and atime

Unix keeps 3 timestamps for each file: mtime, ctime, and atime. Most people seem to understand atime (access time), it is when the file was last read. There does seem to be some confusion between mtime and ctime though. ctime is the inode change time while mtime is the file modification time. ...

Why updating atime doesn't update ctime?

Hi, ctime is the inode change time. If reading a file, its atime will be updated, which should cause inode member i_atime changed, which is an inode change. So ctime should also be updated. But if I try to ls a directory on redhat, only the directory atime gets updated, not ctime. Why? THANKS!

MODERATORS(5)							File Formats Manual						     MODERATORS(5)

NAME

       moderators - mail addresses for moderated Usenet newsgroups

DESCRIPTION

       The  GetModeratorAddress(3)  routine  reads  the file /etc/news/moderators to determine how to reach the moderator of a newsgroup.  This is
       used by inews(1) when an unapproved local posting is made to a moderated newsgroup.

       The file is read until a match is found.  Blank lines and lines starting with a number sign (``#'') are ignored.  All  other  lines  should
       consist of two fields separated by a colon.

       The  first  field  is  a  wildmat(3)-style pattern.  If it matches the name of the newsgroup, then the second field is taken to be a format
       string for sprintf(3).  This string should have at most one %s parameter, which will be given  the  name  of  the  newsgroup  with  periods
       transliterated to dashes.

       Here is a sample file:
	      foo.important:announce-request@foo.com
	      foo.*:%s@mailer.foo.com
	      gnu.*:%s@prep.ai.mit.edu
	      *:%s@uunet.uu.net
       Using the above file, postings to the moderated newsgroup in the left column will be sent to the address shown in the right column:
	      foo.important	  announce-request@foo.com
	      foo.x.announce	  foo-x-announce@mailer.foo.com
	      gnu.emacs.sources   gnu-emacs-sources@prep.ai.mit.edu
	      comp.sources.unix   comp-sources-unix@uunet.uu.net
