RE: Maximum ,Minumum
Hi Ozgur
You can use the following:
@data = (10,45,2,439);
($min,$max) = (sort {$a = $b} @data)[0,$#data];

RE: Maximum ,Minumum
I see what you mean
I assume the following would be a better way of going at it
$max = $min = $data[0];
foreach $val (@data) {
$min = $val$min ? $val:$min;
$max = $val$max ? $val:$max;
}

IMHO sorting a list to find the max and min element is not a good idea.
The sort is of O(nlgn) and the usual
run through the list to find the max element is O(n). This is not of
significance when n is small, at the same
time this is not a method that should be followed for this task.

RE: Adding quotes to a string variable
You have two options: Option one: Put the string between single quotes $a = 'Test Test Test'; Option two: $a = q(Test Test Test); Regards Robert Graham -Original Message- From: Hubert Ian M.

RE: File System Sizes....
You can try the following
($percent) = `df -k` =~ /(\d+)%/;

$percent = `df -k | awk '{print $5}'`;
if($percent 90) {
do something
}
I though that this would work, but I didn't get just the %
column from the
awk statment. I am really trying
to do this all in perl instead of mixing it with awk.
in that case all you need to do is capture the df -k output then regex it.
$percent = `df -k`;
$percent =~/regex_to_capture_number/;

don't have time to look at the output right now and regex but should be
easy.

RE: Regular expression help!!
You can use the following to remove the space in front $Value =~ /s/^\s+//; And for the sake of interest $Value =~ s/\s+$//; will remove any trailing spaces from a string Regards Robert Graham -Original Message- From: Woz [mailto:[EMAIL PROTECTED]] Sent: 25 October 2001 12:04 To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RE: Regular expression help!! Wow, that was fast! Thanks very much, that works well. For my next question (:-)) how can I make it strip the leading space that it leaves on the resulting string. i.e. I want it to strip 'insert_job: ' from the string - note the trailing space. At the moment I have: - ($Value)=$_=~m/(\W\w\S.*)/; ($Value)=$Value=~m/(\S.*)/; but I'm sure there's a far more elegant solution that combines it all into one. Many many thanks for your help.

Then the $dbh-do($SQL); runs the do method of the $dbh object The code you've copied from the cookbook is a bit of nonsense meant as an example. To make it work you have to fill in the driver, the database name etc. in the DBI-connect call and you have to put a legal SQL statement in the $SQL variable. This is covered in the above DBI documentation. In my copy of the cookbook, example 14-7 is a more nearly working example, but you would still have to point it to your database. I know it is an example, as in i can make it work i type it in add the driver add the query and it works perfectly but i'm not happy with that i want to know WHY is works and WHAT it does.

Re: Re:Net::Ping
Hi Jorge
You can define the host name as a string eg.
$host = hostname;
where hostname represents the host name on your network,
and then refer to the string in the ping command:
unless ($p-ping($host))
Hope this helps
Robert Graham
Hi I have the following code:
use Net::Ping;
$p = Net::Ping-new();
unless ($p-ping(cu5s46))
{
require Tk::Dialog;
$dialog =$mw- Dialog( -title = 'NETWORK ALERT BOX',
-text = THE NETWORK IS DOWN,
-font = Arial 16 normal,
-justify = 'center',
-default_button = 'OK',
-bitmap ='error',
-buttons = [qw/OK/] );
$dialog-Show;
}
$p-close;
But I would like to put a variable instead of cu5s46, a variable which
could
represent some host name in my network.
How can i do this?Thanks
