Command description format

How to specify commands

The commands are specified using the following format:

Here, (1) is called an option, and (2) is called an argument.

The following describes the rules for specifying arguments:

• Specify an option first, and then specify an arbitrary name such as a unit name. If you specify any name before the option, the system assumes the entire specification as a name.

• Multiple options can be specified in any order.

• To specify more than one value for one option, use a comma (,) to separate each value.

• Options without a value can be specified in succession.

  Example:

  -a-b-c can be specified as -abc.

• Two-byte options without a value cannot be specified in succession.

  Example:

  -a-ab cannot be specified as -aab, or -cd -cf cannot be specified as -cdcf.

• When specifying options in succession, you can specify a value of the last option.

  Example:

  In -abc xyz, xyz is a value of the c option.

• If you specify a value for an option that does not have a value, the system assumes anything that follows the value to be a name.

• An error occurs if you specify an invalid option.

• To specify a character string beginning with a hyphen (-) for the first name, such as arbitrary-name-X in the above example of command specification, specify --₁ before arbitrary-name-X. (The system assumes anything that follows --₁ to be a name.)

  You do not need to specify --₁ for the second and subsequent names.

  Example:

  To specify two names -jobA and -jobB, specify -- -jobA -jobB.

• You can use regular expressions for names.

• An error occurs if the number of specified names exceeds the limit.

• Character strings specified in arguments are case-sensitive. Be careful to use a correct combination of uppercase and lowercase letters.

Symbols used for command syntax explanations

The following table lists the conventions used in command syntax explanations:

Table 7‒1: Symbols used for command syntax explanations

Symbol	Convention and example
[ ] (brackets)	An item or items enclosed in brackets are optional. Example: [A]means that you can specify A as required (you can omit A if unnecessary). B|C means that you can specify B or C as required (you can omit both B and C if they are unnecessary).
