Here it is
If I get the jist of your issue right.

You have files having a common with date and time stamps affixed in the name. And you have to grab the oldest file first and rename to the common name with a column being appended to the lines in the file.

If I am right you have files for eg.
test_file.20060206.dtd
test_file.20060207.dtd

If that is the case.

If your files are in the current working directory then.

export comm_file_name=test_file.dtd

export curr_file=`l -ltr test_file.* | awk 'NR == 1 {printf("%s",$9);}'`

sed 's/^\(.*\)$/&\|N/' $curr_file > file_temp

mv file_temp $comm_file_name

If the files are not in your current working directory then

dir_name=/var/opt/test/

export comm_file_name=$dir_name/test_file.dtd

export curr_file=`l -ltr $dir_name/test_file.* | awk 'NR == 1 {printf("%s",$9);}'`

sed 's/^\(.*\)$/&\|N/' $curr_file > file_temp

mv file_temp $comm_file_name

I hope it works.

       WMSUN - Dockable WindowMaker SunRise/SunSet App

SYNOPSIS

       wmSun [-h] [-display <Display>] [-lat <Latitude>] [-lon <Longitude>] [-td <TimeDiff>] [-date <yyyymmdd>]

DESCRIPTION

       wmSun displays the current day's Sun Rise and Set Times. You must enter your LAtitude and Longitude correctly for it to work.

OPTIONS

       -h     Display list of command-line options.

       -display <display>
	      Use an alternate X Display.

       -lat <Latitude>
	      Set latitude of observer.

       -lon <Longitude>
	      Set longitude of observer.

       -td <UT - LT>
	      Set  the	difference  beteeen  UT and LT. Useful when you want to show the Sunrise/Sunset at a remote lat/lon without resetting your
	      clock.

	      Set the date to show sunrise/sunset for.

EXAMPLES

       wmSun -lon 106.3 -lat 35.9
	      this would display rise/set times at Los Alamos in local time.

       wmSun -lat 19.58 -lon 155.92 -td 10
	      this would display rise/set times in Kona, Hawaii in local time (in winter -- you need to take  into  account  daylight  savings	at
	      other times of the year).

BUGS

       Who knows? (Let me know if you find any).
