Does this help:

Code:

awk '	# Name interpreter to be used and start the script to be run.
BEGIN {	# Set input and output field separators before we read any input files.
	FS = OFS = "|"
}
FNR == NR {
	# When the number of records read from the current file (FNR) is the
	# same as the number of records read from all files (NR), we are reading
	# data from the control file.
	# For each line read, set the heading data array indexed by the desired
	# heading data to the output field position for this heading.  (The
	# output field position is also the current number of lines read from
	# the control file.)
	hd[$0] = ++hc
	# Skip to next input line without processing later actions in this
	# script.
	next
}
FNR == 1 {
	# When we read the 1st line of the data file, look at each heading...
	for(i = 1; i <= NF; i++)
		# If the heading is an index in the hd[] array...
		if($i in hd)
			# Set the output field order array indexed by the
			# desired output order to the input field number to be
			# printed in that field.
			of[hd[$i]] = i
}
{	# For all lines in the data file print the desired input fields in the
	# order in which they are supposed to appear in the output file...
	for(i = 1; i <= hc; i++)
		# Print the desired field and the output field separator (when
		# the loop variable does not indicate the last time through the
		# loop) or the output record separator (if the loop variable
		# does indicate the last time through the loop).
		printf("%s%s", $of[i], i == hc ? ORS : OFS)
}' ctrl2 source	# End the script and name the two input files.

fwtmp

fwtmp(1M)																 fwtmp(1M)

NAME

       fwtmp, wtmpfix - manipulate connect accounting records

SYNOPSIS

       [files]

DESCRIPTION

   fwtmp
       reads from the standard input and writes to the standard output, converting binary records of the type found in to formatted ASCII records.
       The ASCII version is useful to enable editing, via ed(1), bad records or for general purpose maintenance of the file.

       The argument is used to denote that input is in ASCII form, and output is to be written in binary form.	The arguments and are independent,
       respectively specifying ASCII input and binary output.  Therefor, is an ASCII to ASCII copy and is a binary to binary copy.  should be used
       for reading If is not used, structure is read.

   wtmpfix
       examines the standard input or named files in format, corrects the time/date stamps to make the entries consistent, and writes to the stan-
       dard  output.  A can be used in place of files to indicate the standard input.  If time/date corrections are not performed, will fault when
       it encounters certain date-change records.

       Each time the date is set, a pair of date change records is written to The first record is the old date denoted	by  the  string  old  time
       placed  in the line field and the flag placed in the type field of the structure.  The second record specifies the new date, and is denoted
       by the string placed in the line field and the flag placed in the type field.  uses these records to synchronize all  time  stamps  in  the
       file.   nullifies date change records when writing to the standard output by setting the time field of the structure in the old date change
       record equal to the time field in the new date change record.  This prevents and from factoring in a date  change  record  pair	more  than
       once.

       In addition to correcting time/date stamps, wtmpfix checks the validity of the name field to ensure that it consists solely of alphanumeric
       characters or spaces.  If it encounters a name that is considered invalid, it changes the login name to and  writes  a  diagnostic  to  the
       standard error.	This minimizes the risk that will fail when processing connect accounting records.

DIAGNOSTICS

       wtmpfix generates the following diagnostics messages:

       generates no errors, even on garbage input.
