#!/bin/bash

. data-file    # 加载一个数据文件.
# 与"source data-file"效果相同, 但是更具可移植性.

#  文件"data-file"必须存在于当前工作目录, 
#+ 因为这个文件是使用'basename'来引用的. 

# 现在, 引用这个文件中的一些数据. 

echo "variable1 (from data-file) = $variable1"
echo "variable3 (from data-file) = $variable3"

let "sum = $variable2 + $variable4"
echo "Sum of variable2 + variable4 (from data-file) = $sum"
echo "message1 (from data-file) is \"$message1\""
# 注意:                             将双引号转义

print_message This is the message-print function in the data-file.
