Follow the instructions for individual command syntax explained hereafter. Enter all commands in alphanumeric characters according to the standard UNIX format. Space characters might not be required between the option and the operand. For details, see the format of each command.

The file name of the command you want to execute.
- Option

An option is an alphabetical character starting with a hyphen (-). An error occurs if multiple hyphens or a hyphen alone is entered for an option.
The option may be specified with a character string called an operand to clarify the attribute of options.
When specifying options, note the following:
-
Specify the options in the order they appear in the Format section in each command description.
-
If the same option is specified more than once, the command may result in an error or the last specified option may become valid, depending on the characteristics of the command.
-
When entering a space character in the character string of the operand, enclose the character string in double quotations (").
The following shows an example of option -d with operands 1 and 2.
%Command name -d "1 2"
