unix does not store the creation time, so I am afraid it is not possible to show that.

(blushing) regards and regrets,

You can use perl for this.

perl -e 'foreach(@ARGV){$t =localtime ( ( ( stat ( $_ ) ) [9] ) ); printf("%-20s%s\n",$_,$t);}' *

Hi,

As far as I know there is no info for seconds in the standard 'ls' command.

That is funny because a command like touch,
to create a file allows you to add timestamp including seconds. Where do these seconds go.

Anyway down to the nitty grityy:

someone@somewhere:/opt/mozilla/icons $ ls -l
total 32
-rw-r--r-- 1 bin bin 1668 Mar 5 2004 mozicon16.xpm
-rw-r--r-- 1 bin bin 2944 Mar 5 2004 mozicon50.xpm

Here is a single perl command that can print the timestamp of files with full date and time, accurate down to the seconds:

perl -e 'foreach(@ARGV){$t =localtime ( ( ( stat ( $_ ) ) [9] ) ); printf("%-20s %s\n",$_,$t);}' *

Happy ever after :))

The cpio command will prob. be the solution that will give the information without using perl.

As mentioned, you can check the last modification time with stat(2) and get the time_t value. You can use perl, C or some other language to do this.

A different/better "ls" can let you choose
a (less lame) date-time format.

You could also make a copy of /usr/lib/nls/msg/C/ls.cat and change the default formats:
dumpmsg /usr/lib/nls/msg/C/ls.cat > ls.msg

Change to:
11 %b %2d %Y(%H:%M:%S)
12 %b %2d %H:%M:%S

gencat ls.cat ls.msg

Then invoke ll:
$ NLSPATH=%N.cat ll -tr
