Hi Khurram:

# uptime

...gives the uptime from last boot

# who -b

...gives you the actual boot date/time

Regards!

Try this:

or:

# who -r

You guys, do you know all of you post the reply in the same minute ? It must be a record...

Khurram,

This should tell you the uptime as well.

Also check the timestamp of OLDsyslog.log file in /var/adm/syslog dir

#ls -l /var/adm/syslog/OLDsyslog.log.

This should give the last timestamp of the previous syslog file.

ALso,

#cat syslog.log |head -1

[Jannik]

last boot:
/etc/rc.log
the time before last:
/etc/rc.log.old

This is just another way, but i would think that you are lokking for uptime or who -b as others said.

ps -ef |grep init would also work, but uptime is the way to go.

When I first saw this, I thought it was a Lubomir question!!!!! ;^)

You can get the history of reboots by checking /etc/shutdownlog.

If the file doesn't exist, you can create it using

touch /etc/shutdownlog

Once this is done, any future reboots (including some crashes/system panics) will be logged.

eg:

/etc =>more shutdownlog
08:10 Wed Jun 11, 2003. Reboot:
09:02 Wed Jun 11, 2003. Reboot:
09:14 Wed Jun 11, 2003. Reboot:
10:19 Wed Jun 11, 2003. Reboot:
10:32 Wed Jun 11, 2003. Reboot:
13:58 Wed Jun 11, 2003. Reboot:
13:58 Wed Jun 11, 2003. Reboot:
15:45 Wed Jun 11, 2003. Reboot:
07:55 Thu Jun 12, 2003. Reboot:
07:55 Thu Jun 12, 2003. Reboot:
10:50 Thu Jun 12 2003. Reboot after panic:
16:15 Thu Jun 12, 2003. Reboot:
11:53 Fri Jun 13, 2003. Halt:
12:28 Fri Jun 13, 2003. Halt:

Just for fun. Here is another way:

# last reboot | head -1

[twang]

use the following command to find out how long the system has being up and its svg loading:
# uptime

Hello!

As you say uptime so it's the name of the command that shows the uptime of the machine after the last reboot.

In your question itself there is answer. #uptime or #who -b will show you the system uptime.
