In the spirit of TMOTOWTDI, you could, in your perl script have whatever you are trying to do be done within the context of a signal handler. For example,

#!/bin/perl

$SIG{INT} = \&my_sub;

sub my_sub
{
$SIG{INT} = \&my_sub;
#do stuff
}

while (1)
{
#waiting for my signal...
}

Then, put an entry in the crontab to send your process a SIGINT every minute (kill -INT (your pid here)). You may even be able to put the entry in the crontab through the script (I would try to figure it out myself, but I'm a bit sleepy right now). So, now with the signal handler installed, your script will "do stuff" only when it catches a <code>SIGINT<code>, which you've aranged to be once a minute. You also get the benefit of having your process be persistent, so that the loading of it into memory isn't an issue if it ever was to begin with.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
