Hi,
yes you are correct I hae to replace 'v1' in file ${TMPFILE}1 with line B of file file02.dat
but you script doesn't seem to do that. I mean it replaces some strings but the file that obtain is not what I expect.
This is what I got so far. It doesn't seem to accept the parameter B.

Code:
#/bin/bash
POSITIONS_CASE5=("5" "7" "8" "9" "10" "11" "12" "13" "14" "15" "16" "31" "34" "35" "38" "57" "144" "147" "148" "166" "253" "256" "257" "275" "362" "365" "366" "384" "471" "474" "475" "493" "577")

LINES_CASE5=("3" "4" "5" "6" "7" "8" "9" "10" "11" "12" "13" "14" "15" "16" "17" "18" "19" "20" "21" "22" "23" "24" "25" "26" "27" "28" "29" "30" "31" "32" "33" "34" "35")

ELEMENTS_5A=${#LINES_CASE5[@]}  
ELEMENTS_5B=${#POSITIONS_CASE5[@]}  

echo $ELEMENTS_5A $ELEMENTS_5B
###############################################################################
for i in 1 2
do
  read my_data[$i]
done < file02.dat

INFILE="TEST.inp"
TMPFILE=${INFILE}.tmp
OUTFILE=${my_data[1]}

cp ${INFILE} ${TMPFILE}1
echo $INFILE $TMPFILE $OUTFILE
###############################################################################
DATE
for (( j=0;j<$ELEMENTS_5A;j++)); do
    echo $j ${POSITIONS_CASE5[${j}]} ${LINES_CASE5[${j}]}
    B=${LINES_CASE5[${j}]}
    awk '{if(NR!=v1 ){print;next}system("head -v2  v3|tail -1")}' v1=${POSITIONS_CASE5[${j}]} v2=${B} v3=file02.dat ${TMPFILE}1 > ${TMPFILE}2
    mv ${TMPFILE}2 ${TMPFILE}1
done
mv ${TMPFILE}1 ${OUTFILE}
DATE

I get the rror message
Code:
head: invalid trailing option -- 2

Thanks,
Sarah

LEARN ABOUT PHP

tmpfile

TMPFILE(3)								 1								TMPFILE(3)

tmpfile - Creates a temporary file

SYNOPSIS

       resource tmpfile (void  )

DESCRIPTION

	Creates a temporary file with a unique name in read-write (w+) mode and returns a file handle .

	The  file  is  automatically removed when closed (for example, by calling fclose(3), or when there are no remaining references to the file
       handle returned by tmpfile(3)), or when the script ends.

	For details, consult your system documentation on the tmpfile(3) function, as well as the stdio.h header file.

RETURN VALUES

	Returns a file handle, similar to the one returned by fopen(3), for the new file or FALSE on failure.

EXAMPLES

       Example #1

	      tmpfile(3) example

	      <?php
	      $temp = tmpfile();
	      fwrite($temp, "writing to tempfile");
	      fseek($temp, 0);
	      echo fread($temp, 1024);
	      fclose($temp); // this removes the file
	      ?>

	      The above example will output:

	      writing to tempfile
