Thank you everyone for sharing your thoughts

Hi rwuerth, when i used your code, for some reason it is removing any existing spaces from the record.

i.e. say if the record to be converted is
Code:
 dentonabc12345tx 76201 usa

by using the script you have shared i am geting output as
Code:
 denton12345678tx76201usa

instead i am expecting the output to be as
Code:
 denton12345678tx 76201 usa

perl is very easy to do so
perl -ne '{s/(12345)(?{$cnt++;$tmp = int(($cnt-1)\/4);})/$1+$tmp/e;print;}' yourfile

Posix:
Code:
i=$((12345678 * 4))
while read line
do
  echo "${line%abc12345*}$((i++/4))${line#*abc12345}"
done < infile > outfile

bash/ksh93:
Code:
i=$((12345678 * 4))
while read line
do
   echo "${line/abc12345/$((i++/4))}"
done < infile > outfile
