Top Forums Shell Programming and Scripting Preserve spaces while reading character character Post 302895982 by MadeInGermany on Thursday 3rd of April 2014 03:33:08 PM

Code:
while IFS="" read -r -n1 char

does the trick.
BTW echo -e and echo -n are not portable, better get used to printf:
Code:
printf "%c" "$char"

or
Code:
printf "$char"
