Bash script file read, bash deletes spaces

Question

This questions is a follow up to my previous question about reading certain lines of a file. I read my file as follows:

while read line 
do
    if [ "$line" == "SUMMARY OF POLARIZATION CALCULATION" ]; then
        for i in {1..9}
        do
            read line
            echo $line >> ../../Summary.out
        done
        break
    fi
done < ../Tutorial1_1.out

Which looks like this:

So the code above just take the 9 lines after the "SUMMARY.." and writes to Summary.out file. However, when it writes it screws up all the spacing, so i get the following:

=======================================================================================
Value | spin | dir(1) | dir(2) | dir(3)
---------------------------------------------------------------------------------------
Electronic polarization (C/m2) sp(1) [-8.783054e-12, -8.828765e-13, 4.803326e-01]

Tot. spin polariz.=Pion+Pel (C/m2) sp(1) [ 4.873517e-12, 1.277369e-11, 3.042756e-01]
---------------------------------------------------------------------------------------
TOTAL POLARIZATION (C/m2) both [ 4.873517e-12, 1.277369e-11, 3.042756e-01]
=======================================================================================

How can i fix that, is there a flag that would read and write a string exactly as it is in the input file?

Answer 1

I suggest to use

echo "$line" >> ../../Summary.out

instead of

echo $line >> ../../Summary.out
