Hi Friends,

I have .txt file which has 13000 records.
Each record is 278 character long.

I am using below code to extract the string and it takes almost 10 minutes.
Any suggestion please.

cat filename.txt|while read line
do

f1=`echo $line|awk '{print substr($1,1,9)}'`
f2=`echo $line|awk '{print substr($1,10,20)}'`
f3=`echo $line|awk '{print substr($1,30,50)}'`
f4=`echo $line|awk '{print substr($1,80,10)}'`
f5=`echo $line|awk '{print substr($1,90,50)}'`
f6=`echo $line|awk '{print substr($1,140,10)}'`
f7=`echo $line|awk '{print substr($1,150,50)}'`
f8=`echo $line|awk '{print substr($1,200,10)}'`
f9=`echo $line|awk '{print substr($1,210,50)}'`
f10=`echo $line|awk '{print substr($1,260,10)}'`
f11=`echo $line|awk '{print substr($1,270,8)}'`
f12=`echo $line|awk '{print substr($1,278,8)}'`

s1=`echo $f1"|"$f2"|"$f3"|"$f4"|"$f5"|"`
s2=`echo $f6"|"$f7"|"$f8"|"`
s3=`echo $f9"|"$f10"|"`
s4=`echo $f11"|"$f12`

echo $s1$s2$s3$s4 >> FinalResult.txt
done
