From the previous exercises, you have $2$ files in your Linux installation: file$1.$txt and file$2.$txt$,$ both with one million rows of random numbers. Create a new script, double$\_$numbers.sh$,$ to read each line of file$1.$txt$,$ storing the number from each line into a variable, then write a value that is double the original number into another file called newfile$1.$txt$.$ Once this is done for the entire contents of file$1.$txt$,$ display the time it took to run. Your script might look as follows:

#$!/$bin$/$bash

SECONDS$=0$

while read $-$r number

do

let "number $*=2"$

echo $number $>>$ newfile$1.$txt

done $<$ file$1.$txt

duration$=$$SECONDS

echo $duration
