sleep

Suspend execution for an interval (POSIX)

Syntax:

sleep time

Options:

time
For POSIX conformance, this must be a nonnegative decimal integer, from 0 to 4294967295, specifying the number of seconds to suspend execution.

As a BlackBerry 10 OS extension, time can be a floating point number, so you can specify fractions of seconds.

Description:

The sleep utility suspends execution for at least the number of seconds specified by the time operand.

Exit status:

0
The execution was successfully suspended for at least time seconds, or a SIGALRM signal was received.
>0
An error occurred.

Caveats:

The sleep utility takes the default action for all signals, except that sleep terminates normally with a zero exit status on receipt of a SIGALRM signal.
