1.1 How to input a command

Synopsis

The following show the format for inputting a command:

command_name [option...]

Each item is explained below. Note that $ indicates the command prompt, and cmd indicates a command name.

command_name

Specify the file name of the command to be run.

When you run a command that specifies a path that contains a blank space, enclose the entire path in double quotation marks (""). For example:

• Incorrect example: $ /opt/program path/bin/cmd

• Correct example: $ "/opt/program path/bin/cmd"

(Note that the paths in the examples are different from the paths used in the actual product.)

Input format of options

Options always start with a hyphen (-). Option input formats include a format in which no option argument is specified and a format in which one option argument is specified.

• The following format is used to specify no option argument:

  $ cmd -option_flag

• The following format is used to specify one option argument:

  $ cmd -option_flag space_or_tab option_argument

Legend:

option_flag: This is one half-width alphanumeric character. Characters are case sensitive (uppercase and lowercase characters are distinguished).

option_argument: This is an argument of the option flag.

Rules for specifying options

• You cannot specify all the option flags together with a single hyphen (-). For example:

  Incorrect example: $ cmd -abc

  Correct example: $ cmd -a -b -c

• Option arguments of an option flag that require arguments cannot be omitted.

• A blank or tab space must be inserted between an option flag and its argument. For example:

  Incorrect example: $ cmd -afile

  Correct example: $ cmd -a file

• The same option flag cannot be specified multiple times. For example:

  Incorrect example: $ cmd -a 1 -a 2

• If an option argument includes a blank space, all the option arguments must be enclosed in double quotation marks (""). For example:

  Incorrect example: $ cmd -a file 1

  Correct example: $ cmd -a "file 1"
