问题描述
为什么在解释语言中＃通常会引入注释？这个问题是在Shell编程考试中被问到的，但是我没有找到为什么它是＃的任何提示。
Why in interpreted languages the # normally introduces a comment? This question was asked in an exam on Shell Programming but I don't find any hint on why it's the #.
任何想法吗？
推荐答案
make使用＃注释构造；和sh（第一个外壳程序）使用相同的＃注释。后来的shell（csh，ksh，bash，jsh等）的作者理解，如果每个人都有自己的注释约定，这将给用户带来负担，特别是因为所有这些shell脚本都可以运行在任何壳下。
make uses the #-comment construct; and sh, one the first shells, uses the same #-comment. The writers of later shells -- csh, ksh, bash, jsh, and more -- understood that it would be a burden on users if each were to have its own comment convention, particularly since all of these shell scripts can sort-of run under any shell.
要发明另一种注释约定，就是要确保没有人会使用任何新引入的shell。
To invent yet another comment convention would be to ensure that no one would use any newly-introduced shell.
＃注释在Unix历史上很早就成为事实上的标准。
The #-comment became a de facto standard very early in Unix history.
无论如何，这就是我的想法。
That's my take, anyway.
