General :: Uptime - Getting Date & Time Of System Startup?
Mar 28, 2011
I know that uptime prints the time a machine has been up and running, but is there an easier (reliable) way to get the date of the start up than counting down from this output?I tried looking around /proc, but didn't find anything of relevance. There's also a line like this on my dmesg: [ 0.673492] rtc_cmos rtc_cmos: setting system clock to 2011-03-14 14:26:52 UTC (1300112812), but I'm wondering if this method is distribution and kernel version agnostic.
My Linux system was last rebooted few hours ago. But it seems little confusing for me to figure out the exact reason behind it. I guess following command should justify what i meant to say.
Code: # date Wed May 11 13:22:49 IST 2011 # last | grep "May 10" reboot system boot 2.6.18-194.el5 Tue May 10 17:35 (19:46) root pts/1 XXXX Tue May 10 17:24 - 18:18 (00:53)
[Code]...
My question is Why the uptime is saying that the system is up since last 47 min.It should be more than 1 day if i m not wrong.
I know several tools that allow tracking time spend on different tasks / projects.Is there any existing tool for very very simplified work-time-tracking.I am an employee, come to the office, switch on my laptop directly. I have mostly around 1 hr lunchtime, but sometimes less, sometimes more.At around 18:00 I want to type one command in the console (or simple GUI would also be okay of course) that tells me:"1 hour overworked. Go home now! (came at 8:00, 1 hour standard lunch-break)."
Lucid 10.04, auto upgraded from 9.10, accessed through NoMachine NX from my MacBook Pro 10.6 system.
When I try to access the time settings through the System > Administration > Time and Date menu, all I get is the greyed-out display with the message Not authotized to make changes at the bottom.
With other administration functions, I am asked for sudo-style authorization with my password. That doesn't happen with Time and Date.
I want to change the Date and Time of the system from my application. This can be done using the "Date -s" linux command. But the application has to be executed as root/sudo. is it possible that root can give permission to normal user to execute the "Date -s" command?
I have the application and kernel module running on my system. In the meantime, I am changing the date and time of the system. However, this change doesn't reflect on log messages of the application that's being executed.
rpm -qa --last lists all rpm with date and time. But I want to sort the list by date, with earlier rpm displayed first. So it needs pipe, rpm -qa --last |
Centos 5.4 64bitWould like to know when a particular process was started.1.Quote:ll -d /proc/4014/dr-xr-xr-x 5 mysql mysql 0 Nov 28 07:34 /proc/4014/2.Quote:ps -o pid,lstart -p 4014 PIDSTARTED 4014 Tue Nov 17 23:10:13 20091) Which one should I consider?2) why do both have such a difference?
I would appreciate help with how to extract the date and time from at command jobs. From what I can tell, the date and time is embedded in the file name (/var/spool/atjobs).I'd be using this information in a (bash) shell script.
language: cOs: ubuntu 9.10 want a c or c++ program that gives the system uptime in YYYY: MM: DD HH : MM: SS format.eally it is head ditching..This is not home work or assisgnment..
I have an old computer and BIOS counts the time slower than real. So, how can I set my OS to update the time automatically using the internet? If it updated the time only during booting, it would be enough.
I've got fedora 11 set up to use network time protocol to sync my laptop's date & time when I'm on-line. The question is simple really, I've added a local universality's time server (what is public) and it's live. but it's added to the end of the default time servers what come with fedora. How do I get fedora to just use the local time server, is it a case of removing the default time servers for fedora, but there is a box what says advanced options which are. sync system clock before starting service ???? & use Local time source (( is that the same as the local ntp server that I've got set up ))Hope some body can help me with the network time protocol part of Date/Time settings.
I tried googling but couldnt find the task manager equivalent? Just want to find out how much memory LINUX uses in general as I have been using it for few days and everything seems faster than on vista with no programs freezing! Also on my taskbar, when I click on the time to change it, it doesn't work? I think the timezone is set to US or something but how do i change the timezone?
How do i log the start/completion (time&date) of my cron job script? i want to be able to see what time it started and what time it finished? and if there where any errors while running my script.
I used to have the date and time in the upper right hand corner and then yesterday morning it was just gone. I can't figure out how to get it back up there. I've looked everywhere I thought it would be to put it back on there and I've had no such luck.
I'm trying to find a proper command to move a certain set of files according to date/time range. I am thinking that the command should be something like:
I wrote a hack script that outputs the following every so often: Code: 01/04/11 10:33:02: 97,1413,1447,2860 I must leave the data format the same --but I want a special number from it. In this case it's 97 and it's always going to be the first in the 4 columns of comma delimited items. I can extract with this:
Code: cat datafile | awk -F" " {'print $3'} | awk -F"," {'print $1'} But that's really sloppy. Can someone point out a better way of doing this (with awk) and tell me why?
But i don't know if the system :dowloads the updates if the downloaded updates are immidiately installed some updates need to reboot the system. does it automatically reboot or does he(the system) inform me ? (where ?)
I'm just wondering what the limits for time are. I have a program that always takes exactly 20 ms, so I assume this is the lowest it can measure, but I want to see if there's some sort of documentation of this.
get the values for the user time and system time for a process.i have tried getrusage to get values of ru_utime and ru_stimebut these don't seem to be correct
I want to measure the startup time of any GUI app (e.g. firefox) using the time(1) command. However, timing is measured until the app is closed, which has to be done manually by exiting it or clicking X.
How can I get the app to load, terminate immediately and give me the startup time?
