Shell 电话本解决方案

Shell 电话本
之前用C写了个电话本，今天上班无聊将此电话本改用shell编写。

Perl code

Perl code

#!/bin/shif [ $1 = 'r' ]then    name=$2    awk  'BEGIN{FS=":::"}{if($1 ~ /'$name'/)print $1, $2;}' <phoneno.datelif [ $1 = 'w' ]then    name=$2     fs=":::"    number=$3    echo $2 $fs $number >>phoneno.datelse    echo "Useage:phoneno.sh w Name Number\n       phoneno.sh r Name"fi

Perl code
if [ $1 = 'r' ]; then awk 'BEGIN{FS=":::"}{if($1 ~ /'$2'/)print $1, $2;}' <phoneno.dat; else echo $2 ":::" $3 >>phoneno.dat;fi 
 
[解决办法]
echo "增加信息,请输入性别:"
   read sex
   echo "增加信息,请输入年龄:"
   read age
   echo "增加信息，请输入电话号码:"
   read tellno
   while [ -z $tellno ]
   do
       echo "电话号码不能为空，请重新输入电话号码:"
       read tellno
   done
   echo "增加信息,请输入QQ:"
   read QQ
   echo "增加信息,请输入E-MAIL:"
   read email
   echo "增加信息,请输入出生年月:"
   read birthday
   echo $name \| $sex \| $age \| $tellno \| $QQ \| $email \| $birthday \| >> phoneno.txt


不知这段代码是否可以写在一个方法里面，方便复用。
开始学了两天的bash shell了，代码基本上看得懂，不过暂时还写不出来。对于junior,是学习shell很不错的范例代码
