sleep

See the current Perl documentation for sleep.

Here is our local, out-dated (pre-5.6) version:


sleep - block for some number of seconds


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 number 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.

See also the POSIX module's sigpause() function.

[james28909]: and that is also anothe rpoint i made, i think it has to do with perception of the world around you. most people think of evolution on a human scale. why could life evolve on this planet? because this planet evolved in this solar system. and so on.
[holli]: here's something for you to watch, James. I think you will like it
[erix]: for the record: I have not downvoted anyone on that subthread that was my fault
[james28909]: there are all kinds of things that had to happen to let life come to be. but at the same time, life may not be the end goal IF there is any kind of end goal lol
[james28909]: well who is the person who gets to decide which behaviour is worthy of a downvote? a person with their own beliefs? xD
[erix]: teleology -- I've never understood why that was thunk up
[erix]: ( and when teleology was brought up, during my biology-study., I couldn't get an answer either )
[1nickt]: FTR I agree with you about "design." Just not sure about the trajectory of evolution. THere are a lot of dead-ends in the evolutionary paths. I suspect homo sapiens is just one of them.
[james28909]: thanks for the vid holli, i do like it. thanks for sharing :)
