1、字符串处理，

请编写脚本code1.sh，要求输入逗号隔开的若干个名字，每个名字单独输出hello名字，how are you

例子：

输入 sh code1.sh perter,ken,zoe

则输出

hello peter,how are you！

hello ken,how are you！

hello zoe,how are you！


脚本功能如下

#!/bin/bash

nf=`echo"$1"|awk-F,'{printNF}'`foriin`seq1$nf`doa=`echo$1|cut-d','-f$i`echohello$a,Howareyou!done


执行结果如下

[root@localhostopt]#shb.shperter,jenkins,tomhelloperter,Howareyou!hellojenkins,Howareyou!hellotom,Howareyou!
