You can use the command:

last -x
last reboot
last shutdown
Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?

Here's a handy Perl script you can use -

#!/usr/bin/perl

my $input = "/proc/uptime";
open (INPUT, "$input") || die "Can't open file $input : $!\n";
while () {
($secsago) = (split(/\s+/))[0];
}
$boottime = time() - $secsago;
$bootdate = localtime($boottime);
print "$bootdate\n";

Re: RedHat boot Question

What i am looking for is a complete history of shutdowns/reboots for this server. Is there a log file with that information available?

Shalom,

No, there is not a complete history available.

Here is why.

AS 4.4 ships with logrotate configured to run. It archieves /var/log/messages and keeps 4 copies, so the farthest you go back is 5 weeks.

Now if your system has been altered, you may have more information, but by default you get 5 weeks.
