Title
Body
I'm having this code from http://bash.cyberciti.biz/guide/While_loop , used to read line by line from a file file=/etc/resolv.conf while IFS= read -r line do # echo line is stored in $line echo $line done < "$file" the part I don't understand is IFS= and how it contributes to this functionality. Could anybody explain this to me? Thanks.
