$ cat /proc/uptime

The first column is the host's uptime seconds.

Hi,
You could use the distribution: Unix::Uptime
(http://search.cpan.org/perldoc?Unix::Uptime)
Example:
use strict;
use warnings;
use
Net::SSH qw( sshopen3 );
my $user = bob;
my $host = 10.10.10.10;
my $cmd = uptime;
sshopen3( $user\@$host, *WRITER, *READER, *ERROR, $cmd );
my $uptime = READER;
chomp $uptime;
print $uptime\n;
something like that ought to so it...
Also if you do use Net::SSH, you need to use key authorization

It may be easier to go by route of the Net::SSH::Perl module or

Prase the output of the command
you could try snmp but that (in my experience) always reports the wrong
time if over 2 days.

Here is a script I use to check system up time. You can specify a remote
server as an argument and it will remotely check the uptime for that server.
This goes into the perfmon stats and gets the information from there.

Damn if you're gonna do it this way , why not just do:
uptime

I misunderstood. I thought Ken was asking the opposite of what Jim
posted...
If you want a least effort solution, you can do it without perl. Just
modify your bash script:
w | head -1 | cut -d, -f1-3
A cleaner way would be to just use uptime, as Ken said:
uptime | cut -d, -f1
Am I just the overly paranoid one? But IMO doing this can be dangerous.
Tainting isn't just for CGIs, and adding a -T to this shows it can be
dangerous ($ENV{PATH} issue, since you don't really know what uptime you will
end up calling). Again, I may be the overly-paranoid (read safe) one
right now i do
w | head -1
and get what's below my signature. I want to clean that up, cutting it
after the # of users, so that everything after AND including the third
comma is removed from that line. Then take that and add it to my signature
script. i can either send it to a new file and
on what you are really trying to do here but
the first thing that comes to mind is...
if you want your uptime...why are you using w | blah blah blah? You could
simply use uptime(1) couldn't you?
If you are really hell-bent on going the 'w | head -1' direction and
redirecting that into a file, you
uptime, as (correction) Jim said:
uptime | cut -d, -f1-3
Since it's a perl list, and you asked how to do it with perl...
Yes. Thank you for doing this. I apologize for the OT'ness of my reply.
:) Let me continue a perl tradition:
perl -MShell -e 'chomp($uptime = uptime());($a,$b,$c
