Question

我在Unix中编写了这个脚本：

function addinfo {
  echo "Please enter your LAST Name: "
  read last
  echo "Please enter your FIRST Name: "
  read first
  echo "Please enter your PHONE number as XXX-XXX-XXXX: "
  read phone
  if [ $phone != ???-???-??? ]; then
    echo "Please only enter your as XXX-XXX-XXXX"
    read phone
  else
    echo $last + $first + $phone >> asg7phonebook
  if
}

我收到与最后一个括号相关联的错误代码。

布尔条件可以在Unix函数中运行吗？
如何让我的功能检查用户是否输入XXX-XXX-XXXX（其中＆＃34; X＆＃34;是他们的电话号码）作为有效数字输入？我想阻止用户输入23435-3422 2作为号码，或输入1234567890作为号码。
我的语法是否正确？

Answer 1

我发现您的方法存在一些问题，

#!/usr/bin/env ksh

addinfo() {
  echo "Please enter your LAST Name: "
  read last
  echo "Please enter your FIRST Name: "
  read first
  echo "Please enter your PHONE number as XXX-XXX-XXXX: "
  read phone
  # Using a while loop on the correct pattern check.
  while [[ "$phone" != [0-9][0-9][0-9]-[0-9][0-9][0-9]-[0-9][0-9][0-9][0-9] ]]
  do
      echo "Please enter your PHONE number as XXX-XXX-XXXX (only): "
      read phone
  done
  echo $last + $first + $phone >> asg7phonebook
}

addinfo

Answer 2

#!/bin/bash
function addinfo() {
  echo "Please enter your LAST Name: "
  read last
  echo "Please enter your FIRST Name: "
  read first
  echo "Please enter your PHONE number as XXX-XXX-XXXX: "
  read phone
  if [[ $phone =~ ^[0-9]{3}-[0-9]{3}-[0-9]{4}$ ]]; then
    echo $last:$first:$phone >> asg7phonebook
  else
    echo "Please only enter your as XXX-XXX-XXXX"
  fi
}

addinfo

@Elliott Frisch的答案是一个有效的解决方案，但只是为了使用{{1>}的扩展模式来显示更简单的匹配选项：

ksh 93
