Thanks chubler
that awk worked.
But It displayed everything in the log file.
Not just 1 hour back.

Can you paste the first line that is displayed here please.
I suspect your datafile doesn't match the posted format particularly check that the year is two digits and not four, ans make sure no additional spaces are in between the dates, eg " 8" for the month.

OK you have lines that don't match the format at the start of the file.


v=$(date --date "-1 hour" +"-vY=%-y -vT=%-m -vD=%-d -vH=%-H -vM=%-M")
awk -F '[[ /:]' $v '
  $4+0>Y ||
  $4+0==Y&&$2+0>T ||
  $4+0==Y&&$2+0==T&&$3+0>D ||
  $4+0==Y&&$2+0==T&&$3+0==D&&$5+0>H ||
  $4+0==Y&&$2+0==T&&$3+0==D&&$5+0==H&&$6+0>M {v=1}
  v' infile

Thanks Chubler,

This avoided the files that do not have timestamp at the start of the file.
But displayed all the lines with the time stamp and also lines in the missdle without timestamp.

And the lines with the timestamp ar enot within an hour.all the lines are picked.

Change last line to /^[[]/&&v' infile to avoid non-date lines following the first match.

I don't know why you are matching dates older than 1 hour, could you post the first line that matches again,
between [code] and [/code] tags so the format isn't lost.

Thanks Chubler.
Yes this displayed only the lines with the time stamp.
But not from last hour. All the lines from last 4days are also displayed.
appreciate your help.
