Hi,

I have a requirement to replace 5 characters from position 8 for a each line with spaces in shell script.

Input:

001ABCD00001XYZ
097XYZU00034NYU
457GFDS08654YGT

Required Output:

001ABCD XYZ
097XYZU NYU
457GFDS YGT

Could you someone please help me with the command to be used in UNIX.

Appreciate your help.

One way is to use the unix cut command to save the strings you want and glue them back together:

#!/bin/ksh

while read myline
do
  var1=$(echo "$myline"|cut -c1-7)
  var2=$(echo "$myline"|cut -c13-)
  echo "${var1} ${var2}"
done < dfile1.txt

@nails, with ksh, you can use substring. 
var1=${line:0:7}
var2=${line:12:}

@OP, you can use awk

awk '{print substr($0,1,7) substr($0,13) }' file
