echo $line 
# ${VAR#EXPR} strips the shortest possible string that matches EXPR
# from the front.  So it chops off the first bit and stops at the first space.
echo ${line#* }
# Like #, but strips the LONGEST match.  So it stops at the last space.
echo ${line##* }
# Like #, but strips the shortest match from the back of the string.
# It stops at the second-last space.
echo ${line% * }
