Shell腳本 - 基於用戶輸入的電子郵件腳本

Question

我想創建一個電子郵件腳本，它實際上是一個使用郵件-x併發送給號碼的短信腳本。它會是這樣的：

#/bin/sh 

Joe=8881235555 
Bob=8881235556 

echo "Who do you want to text?:(i.e. Joe, Bob, etc)" 
read name 
echo "What do you want to say?:)" 
read quote 
echo "texting $name with $quote" 

echo $variablequote | mailx -s "Text Message via email" $variablename@txt.att.net 

如何獲得該用戶輸入名稱轉移到預設值？

考慮使用更現代化的外殼：

#!/bin/bash 

# Use an associative array, and map names to numbers 
declare -A numbers 
numbers=([Joe]=8881235555 [Bob]=8881235556) 

echo "Who do you want to text?:(i.e. Joe, Bob, etc)" 
read name 
echo "What do you want to say?:)" 
read quote 

# Look up number by name 
number=${numbers[$name]} 

if [[ $number ]] 
then 
    echo "texting $name ($number) with $quote" 
    mailx -s "Text Message via email" "$number@txt.att.net" <<< "$quote" 
else 
    echo "Unknown user" 
    exit 1 
fi 

如果你想使用/ bin/sh的：

#!/bin/sh 

# Prefix the numbers with something 
number_Joe=8881235555 
number_Bob=8881235556 

echo "Who do you want to text?:(i.e. Joe, Bob, etc)" 
read name 
echo "What do you want to say?:)" 
read quote 

# Remove any dangerous characters that the user enters 
sanitized=$(printf "%s" "$name" | tr -cd 'a-zA-Z') 

# Look up by evaluating e.g. "number=$number_Joe" 
eval "number=\$number_$sanitized" 

if [ "$number" ] 
then 
    echo "texting $name ($number) with $quote" 
    printf "%s\n" "$quote" | mailx -s "Text Message via email" "$number@txt.att.net" 
else 
    echo "Unknown user" 
    exit 1 
fi 

在bash
