 Reading records from file and inputting in a template
    Iam newbie and Iam stuck up with this problem. I have these 2
files. demodat.dat and input.dat
  Field1     Field2
  1          2
  2          3
  3          4
  4          5

  1 (<Field1>)
  2 (<Field2>)

        I have to read the records from demodat.dat and enter the
fields in input.dat in a particular format. I have to create multiple
input.dat files equalling the number of records in demodat.dat. How do
I do this.

Your help is appreciated.

   Basically, you will read the records from demodat.dat (use a "while
   read" loop), and print them out in the new format (using echo or

I think I have an idea what you want... If you are using bash or bourne
shell you could use a while loop something like (the printf should all be
one line):


while read a b c
        if [ "$a" != "Field1" ]
        printf "constant_value\nconstant_value\n1 $a\n2
$b\nconstant_value\n" > input$x.dat

done < demodat.dat

there should be a "then" somewhere around here someplace (geez, I sould not
do these things off the top of my head!!

and a "fi" here! I should also say that this is off the top of my head and I
didn't test it but I hope it gets you going the right direction...
