Syntax and Conventions for CLI Commands

boolean

A boolean has a value of either TRUE or FALSE and can be specified

with any of the following key words:

■ TRUE can be specified with TRUE, 1, ON, or YES. For switches,

you can also specify TRUE by using the switch without any

switch value. For example, /readonly and /

readonly=TRUE are identical.

■ FALSE can be specified with FALSE, 0, OFF, or NO. When a

switch is not specified, it takes the default value (usually,

FALSE) specified in the switch description section of a

command. For example, open aac0 is the same as

open /readonly=FALSE aac0.

integer

An integer is a positive or negative number that has a value between

–2

and (2

– 1). Although the valid range is usually much smaller,

all integers have 64 bits of precision and do not contain decimal

points.

You can specify an integer as a mathematical equation that uses an

asterisk (*) to multiply, a plus sign (+) to add, a minus sign (–) to

subtract, a slash (/) to divide, and parentheses [( )] to specify order

of operations. If you do not use parentheses, all operations are

completed left to right. No spaces are allowed in the expression.

Numbers in an equation that:

■ Begin and end with no suffix are decimal

■ Begin with 0x or end with h are hexadecimal

■ End with o indicate octal

■ End with z indicate binary

You can attach special multipliers to the end of any number to allow

for easy translation to reasonable disk sizes. Table 3-1 lists the letters

and their multiplicative values:

1 2 ... 30 31 32 33 34 35 36 37 38 39 40 ... 353 354
