ls -ltr | awk '{printf "%s\t%s\n",$6,$7;}'
Note however that that date field in the output of ls can have
different formats.

How about
ls -ltr | awk '{ printf("%s %s\n",$6,$7); }'

| Hi Guys.,
thanks for the suggestions. both the suggestions are working.
ls -ltr | awk '{printf "%s\t%s\n",$6,$7;}'
ls -ltr | awk '{ printf("%s %s\n",$6,$7); }'
when i execute the above command it gives me all the values in the
fields 6 and 7.
i am looking in the output to display only march 21. ( i.e today's
date) .
can you please give me a suggestion.
thanks
pavi

Yes. Read:
man awk

Well, that's easy:
echo hi|awk '{ print "Mar\t21" }'
Or, if you want the current date if you run this tomorrow and beyond:
set $(date)
echo hi|awk '{ print "'$2'\t'$3'" }'
:-)
(Point of this satirical post: Providing a good specification for a problem
solution, even a seemingly simple one, is often difficult and requires great
precision. You need more precision in your problem statement if you want
to cut down on the number of repetitions of: "Yes, that does xxx nicely,
but that's not what I asked for - I asked for yyy.")

You can do it in Perl:
perl -MPOSIX -le'print strftime( "%b\t%e", localtime +( stat
"START.TTN.20060321.095017.ctl_20060321095032" )[ 9 ] )'
