利用for循环和shell数组打印下面这段话英文字母数不大于5的单词：
You have the most beautiful age, do not disappoint your best self
老规矩，首先分析： 1.找重点，for 和数组 2.字母书小于5的单词
value=(You have the most beautiful age, do not disappoint your best self) for ((i=0;i<${#value[*]};i++)) do if [ ${#value[$i]} -lt 5 ] then echo ${value[$i]} fi done
第二种方法
for word in ${value[*]}
do
if [ expr length $word -lt 5 ];then
echo $word
fi
done
[root@node1 ~]# sh test.sh You have the most age, do not your best self
测试成功
方法还有很多，大家可以试试~
