Thanks.

I adjusted the script as below

Code:
#!/usr/bin/ksh
PAR1=$1
PAR2=$2
PAR3=$3

awk '{y=substr($2,1,4); f=b} y<lt{f=a} y>gt{f=c} {print>f} ' lt="${PAR1}" gt="${PAR2}" a=y1 b=y2 c=y3 $PAR3

Few more adjustments I need to make.
  1. How to append input filename portion to the resulting files y1,y2,y3

    Example : Input FileName = abc_123~xyz

    Desired Output FileName = abc_y1_123~xyz
  1. At this point I do not whether it would be coulum 2 that I have to check , instead of including column 2 can I just go by position on the substr ?

    Example :

    Code:
    awk '{y=substr($0,1,4); f=b} y<lt{f=a} y>gt{f=c} {print>f} ' lt="${PAR1}" gt="${PAR2}" a=y1 b=y2 c=y3 $PAR3


Please advise on the above...Thanks

       --luns=LIST
