The following works correctly on bash:

 a=$(echo '111 222 33' | awk '{print $3;}' )
 echo $a # result is "33"

Another option would be to convert the string to an array:

 a="111 222 333"
 b=($a)

 echo ${b[2]}  # returns 333

或者你可以直接使用：

${INDEXCOUNT##* }

这可能更容易用于测试if语句/

INDEXCOUNT="111 222 333"
echo $INDEXCOUNT | awk '{if ($3 == 333) print $3}';
