elunatic has asked for the wisdom of the Perl Monks concerning the following question:

im reasonably new to perl and i need to create a timer to delay use of a publicly messaged command... problem is the shell i plan to run this script on doesnt have any of the good 3rd party modules so im stuck trying to make a timer on my own and have no clue how.... help plz?

    How about the built-in sleep function?

    If that isn't suitable, then you'll probably need to provide a little more detail about what you are wanting to do.


      what im trying to do is create a weather script for an irc bot i made with IO::socket, but before i use the weather script on it i need to ensure users cannot flood the bot or channel using the publicly msg'd command.

      right, but i do not have root access on the box in question, which makes it sort of a pain with certain modules... unless you can point me in the right direction to do it without root **as i said im pretty new to this** much thanks guys.

    what do you mean by "delay use"? Do you probably mean sleep? this function can cause the script to pause for the amount of seconds specified or forever if no seconds were specified. Consider this very simple example:
    for($num=5;$num>0;$num--){ print "$num\n"; sleep 2; }
    It'd take a while after printing the current value of $num and looping once again as affected by the duration of time provided in the EXPR to sleep. Best of luck...
