Something annoying about ls -l command is it shows only hour and minute for a file(like 08:30). How can I see the second portion(like 08:30:44)?

man 1 ls and search for 'second' does not give any clue.

Does your version of ls support the --time-style option? If so:

ls -la --time-style=full-iso blah

-rw-r--r-- 1 root root 0 2011-11-08 18:02:08.954092000 -0700 blah

Yes, thanks, even on a old Mandrake Linux 10.0 from year 2005. --full-time OK as well. – Jimm Chen Nov 9 '11 at 2:08

The more simple way is:

ls --full-time

which is equal to

ls -l --time-style=full-iso

If you want to show entries as hidden files starting with ., add -a:

ls --full-time -a

An alternative to the approved answer - you can use a custom format like in the date command if "--time-style=full-iso" output is too detailed for you:

ls -l --time-style=+"%b %d %Y %H:%M:%S" blah
-rw-rw-r-- 1 root root 0 Feb 03 2014 01:13:01 blah

For OS X, it looks like the best you get is:

ls -l -T

From the ls(1) manpage on 10.10.5:

-T When used with the -l (lowercase letter ``ell'') option, display complete time information for the file, including month, day, hour, minute, second, and year.

For FreeBSD, it would be:

ls -la -D %Y-%m-%dT%H:%M:%S

Regarding to man ls instructions simply ls -e works fine !

Which version of GNU coreutils do you use? With 8.20 I don't have this parameter. – sebix Nov 29 '14 at 11:36
