Literal

A word or character that you enter literally.

Replaceable

A word or phrase that you replace with an appropriate value.

-chars

One or more grouped command options, such as -ikx. The chars are usually a string of literal characters that each represent a specific option. For example, the entry -ikx is equivalent to the individual options -i, -k, and -x. The plus character (+) is sometimes used as an option prefix.

-word

A single command option, such as -help. The word is a literal keyword. The difference from - chars is usually obvious and is clarified in an Options description. The plus character (+) and the double hyphen (--) are sometimes used as option prefixes.

[   ]

The bracket metacharacters enclose optional content in formats and command descriptions.

{   }

The brace metacharacters enclose required content in formats and command descriptions.

|

The bar metacharacter separates alternatives in a list of choices, usually in brackets or braces.

. . .

The ellipsis metacharacter after a token (abc...) or a right bracket ([   ]...) or a right brace ({   }...) metacharacter indicates that the preceding element and its preceding whitespace, if any, may be repeated an arbitrary number of times.

. . .

Ellipsis is sometimes used to indicate omitted items in a range.
