Is there a standardized syntax for Linux prognam?

Question

On a Linux system, typing is typical progname --helpto see the help output for this program. After that, you will see a description of the type:progname [SWITCHES] [FILES]... [ETC]

My question is: is there a standardized syntax for its appearance (using the command line)?

To describe things like extra keys, a few options (like a list of files), switch patterns, etc. There seems to be a standard so that anyone who knows it can accurately interpret your documentation.

Note. This is purely writing my documentation, not an analysis of the arguments.

Answer 1

I have looked at many linux man pages, and here are a few things I have seen that seem to be standard for the manual pages that come standard with Linux. Like some of the above authors, there is no published documentation standard. I saw some differences on the Internet, but the pages that come with Linux look pretty consistent.

• The corresponding command will appear first.
• Things that are parameters provided by the user are placed in angle brackets "<>" with the name specified inside the brackets that describes the parameter. ex.
• Parameters that are optional are enclosed in square brackets, "[]".
• , , "|", "".
• dot dot dot "...", , . . [...].
• . , . "filename" "file_name", " ".

There is http://www.gnu.org/prep/standards/standards.html#g_t_002d_002dhelp and http://www.gnu.org/prep/standards/standards.html#Option-Table

But I do not see a strict standard definition ...
