Improve script and get new output file

Gents,

Using the following script, I got the changes as desired in the output file called (spread_2611.x01.new). Complete file as input (spread_2611.x01).

Can you please have a look to my script and improve it please.

Also I would like to I get a additional selecting only the records were the changes were done, please.

Here my script and attached the data to run the script.

Code:

#!/bin/bash
             read -p "First : " fsw
             read -p "Last  : " lsw

file="datatochange.txt"

touch $file

        for swath in $(seq $fsw $lsw)
              do 
awk '{\
	ori_line=substr($5,1,5);\
	ori_point=substr($5,6,5);\
	off_line=substr($1,2,5);\
	off_point=substr($1,7,5);\
	printf ("spread_'${swath}'.x01 %5d.00   %5d.00 %5d.00   %5d.00\n",ori_line,ori_point,off_line,off_point)}' $swath"offb1-Sx.sps" >> $file

done

awk '{F=$1;a[F];e=(F~/x01$/)?"  ":z;s=$2"  "$3;p=$2"  "$3;r=$4"  "$5;
print "s/" s "/" r "/" >> F".sed"
}END{
for(i in a){print "sed -f "i".sed "i " >>"i".new">>"changeindex"}
}' datatochange.txt

sh changeindex

awk '{print $1}' datatochange.txt | uniq > datatochange1.txt 

awk '{a[$1]++ ; print $1}' datatochange1.txt | while read i
mv "$i" "$i.old" && mv "$i.new" "$i"
rm -f "$i.sed"
done

Later I will use this script to change many files at the same time.

Thanks for your help

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
