1.1.1 Specifying a command

Specify a command as follows:

[Figure]

The parameters marked (1) are called options. All the parameters marked (2) are called arguments.

You can specify arguments as follows:

Specify an option or options first, and then specify an arbitrary name or names, such as a unit name. If you specify an arbitrary name before an option, the system handles all specified arguments as arbitrary names.
You can specify multiple options in any sequence. The same option, however, cannot appear more than once.
You can specify multiple values for a single option by using commas to delimit them.
You can collectively specify several options having no values.

Example:

You can specify -abc instead of -a-b-c.
You cannot collectively specify several two-byte options having no values.

Example:

You cannot specify -a-ab as -aab or -cd -cf as -cdcf.
You can specify a value for the last option of those collectively specified.

Example:

In -abc xyz, xyz specifies the value of c.
If you specify a value for an option having no value, the system handles that option and all subsequent arguments as arbitrary names.
Specifying an unexpected option results in an error.
See 1.1.2 Specifying a unit name for notes on specifying a unit name for an arbitrary name.
See 1.1.4 Specifying wildcard characters for notes on specifying wildcard characters for an arbitrary name.
To specify the first arbitrary name (arbitrary-name-X in the above example) with a string starting with "-", enter -- arbitrary-name-X. (The system handles the string following -- as an arbitrary name.) The specification of the second and subsequent arbitrary names does not require --.

Example:

To specify two arbitrary names (-jobA and -jobB) in series, enter -- -jobA -jobB.
You can use regular expressions for an arbitrary name.
Specifying a number of arbitrary names exceeding the expected maximum results in an error.
Characters specified as arguments are case sensitive. Be careful about the case.
