Re: A small queestion to match processes

[jwkrahn]

    #obtain the length to match according to ps aux
   {
        print "#Enter the block just once\n";
        last if $strindex;
        $strindex = index($_, "STAT"); 
        #obtain how characters the RegEx should not match
   } #no more of this besides the first line

A simpler way to do that:

    $strindex = $-[0] if ?STAT?;

Thank you, will look into it ASAP. Still unknown syntax to me.

G'day heatblazer,

It would have been useful if you specified which syntax you didn't know about. Here's a couple of guesses:

• $-[0] is the first element in the array @- which is described in perlvar.
• ?STAT? is described in perlop - Regexp Quote-Like Operators under ?PATTERN?. Regular expressions are described in perlre.

Also, take a look at perl - perldoc.perl.org. Here you'll find links to all the Perl manual pages. I wouldn't suggest attempting to learn everything in all that documentation; rather, just get a feel for where that information can be found. Once you are familiar with what's available, looking up specifics is usually a fairly easy task.

Thank you, I`ll look into these. I was just in a hurry before the idea blows off my head ( as usually happens ), so when I get better, I`ll rewrite it the lazy way :)
