Read file line spaces
I have a script which read a file it does
while read -r line, then i echo line out
echo "$line"

Problem is the echo does not echo space and tabs at the end of each line. How do i get the end of line space as well

Try :
Code:
while IFS= read -r line
do
   echo "[$line]"
done

If you simply want to echo each line out with its tabs and spaces on the end of each line then you can use nawk: -

Code:
nawk 1 file

This will loop through the file echoing each line onto stdout without modifying them

I thought you must be but what are you doing with it?

If you post your code you are more likely to get a useful answer....
