推荐答案

我看到很多Windows命令行的细节，但如果你的程序是适用于Linux，我发现 GNU命令行标准是最直观的。基本上，它对命令的长形式使用双连字符（例如， - help ）和短版本的单个连字符（例如， -h ）。您还可以将短版本堆叠在一起（例如， tar -zxvf filename

I see a lot of Windows command line specifics, but if your program is intended for Linux, I find the GNU command line standard to be the most intuitive. Basically, it uses double hyphens for the long form of a command (e.g., --help) and a single hyphen for the short version (e.g., -h). You can also "stack" the short versions together (e.g., tar -zxvf filename) and mix 'n match long and short to your heart's content.

GNU网站还列出了标准选项名称

The GNU site also lists standard option names.

getopt库大大简化了解析这些命令。如果C不是您的包， Python 具有类似的库， Perl 。

The getopt library greatly simplifies parsing these commands. If C's not your bag, Python has a similar library, as does Perl.
