$ perldoc -f sleep
sleep EXPR
sleep Causes the script to sleep for EXPR seconds, or forever if
no EXPR. May be
interrupted if the process receives a signal such as
"SIGALRM". Returns the num‐
ber of seconds actually slept. You probably cannot mix
"alarm" and "sleep"
calls, because "sleep" is often implemented using "alarm".
On some older systems, it may sleep up to a full second
less than what you
requested, depending on how it counts seconds. Most modern
systems always sleep
the full amount. They may appear to sleep longer than
that, however, because
your process might not be scheduled right away in a busy
multitasking system.
For delays of finer granularity than one second, you may
use Perl’s "syscall"
interface to access setitimer(2) if your system supports
it, or else see "select"
above. The Time::HiRes module (from CPAN, and starting
from Perl 5.8 part of the
standard distribution) may also help.
See also the POSIX module’s "pause" function.
