到这时，用户可以编写shell脚本，在变量中存储信息和导出信息，控制文件描述符，控制信号处理，使用for循环和case语句，以及其他大量功能。
Now, users could write shell scripts; store and export information in variables; control file descriptors; control signal handling, for loops, and case statements; and so much more.

虽然任何科学专业的新手都知道，你不能把“50米/秒”和“30秒”相乘来推导出一个单位是“kg-meters/second”的变量，但是大多数编程语言却不是这样聪明。
While any freshman science major knows you cannot multiply "50 meters per second" by "30 seconds" and shove it a variable expecting "kg-meters/second", most programming languages aren't so smart.
这是基本的部分；它声明了程序需要Perl 5.006 来解释执行，要求进行严格的变量检查和警告，还有我们将要导出 invlist() 和 data_from_invlist()函数。
