Nice looking site; useful and clear information. Good job!

The only problem with the uptime command is that it isn’t always obvious what units of measure to the time it has been up. Just a bit confusing for those new to it, especially those from the Windoze world trying to come over to Linux. Just fleshing out the units (up 5 hours:54 minutes (days:hours:minutes)) on this would certainly help in bringing more over, especially if we can get into the man&info pages.

$ uptime
07:55:56 up 3 days, 17:37, 6 users, load average: 0.04, 0.06, 0.01
$

by default it will give how many days the OS is up, and how many hours:mins.
if it less than 1 day, it will give only hours:mins.

what is the command for checking how many bites are already downloaded in your server

How do I get only time information excluding other load information

How do I get only time information excluding other load information

# 1. run Command
# 2. strip unneeded leading data
# 3. check if the uptime is greater than 24 hours
# 4. make the output human readable
# 5. trim any leading space

For people who want to get uptime within a C program I would suggest having a look at sysinfo() too…

nice and so useful
thank you

How can i know uptime of a server machine without logging in it ?? Is there any way?

Hello Buddies , plz specify whats the value ‘4:29’ in the above output.

@Kunal It’s 4 hours and 29mins. So from the output the server uptime is 13 days, 4 hours and 31 mins.

thanks for this!

Did you see the output within one hour of startup? Is it, e.g. 0:15, :15 or 15 for the 15 minutes after startup?

On most systems you can do cat /proc/uptime if you’re only interested in the uptime. The first number is how many seconds the system has been up for, and the second number is how many seconds it’s spent idle.

Tuptime is a uptime with steroids, nice tool for getting uptime, downtime and other interesting stuff:
https://github.com/rfrail3/tuptime

How can i see the only up time without any other information is there Any command to know only the Uptime i mean to say the if i issue a command it should print 21:54:11 up 13 days, 4:29

Как узнать uptime в Linux/Unix

Нужно проверить uptime сервера? Нужно узнать когда был последний reboot ( перезагрузка)? Не знаете как? Я расскажу вам как можно проверить uptime вашей ОС (Linux\Unix), приведу в своей статье «Как узнать uptime в Linux/Unix» 3 способа как это можно сделать.

1. Команда top.

Top — программа для слежения за активностью процессора в реальном времени. Он отображает список наиболее ресурсоемких задач в системе и может обеспечить интерактивный интерфейс для управления процессами. Программа может сортировать задачи по загрузке процессора, использование памяти и времени автономной работы. Так же есть улучшенная версия под названием htop, которая дает возможность пролистывать и смотреть каждый процесс. Так же данная программа может показать время последней перезагрузки (uptime), чтобы посмотреть это, выполните:

посмотреть uptime с помощью утилиты top

2. Команда w.

Команда (утилита) w — отображает информацию о пользователях которые в настоящее время есть на машине, и их процессов. Внутри заголовка, показывается текущее время, как долго система работает, сколько пользователей в настоящее время вошли в систему, и среднюю нагрузку системы за последние 1, 5 и 15 минут

3. Команда uptime.

uptime дает одно строчную информацию на экран. Он показывает текущее время, как долго система работает уже, сколько пользователей в настоящее время залогинились в системе и среднюю нагрузку системы за последние 1, 5 и 15 минут.

Linux Uptime Command With Usage Examples

The Linux Operating System is filled with several commands which any aspiring Linux expert or power user e.g. system admin must have a good grasp of. One of such commands is uptime and today, I’ll briefly discuss its purpose and syntax.

Uptime is a command that returns information about how long your system has been running together with the current time, number of users with running sessions, and the system load averages for the past 1, 5, and 15 minutes. It can also filter the information displayed at once depending on your specified options.

uptime uses a simple syntax:

Using Uptime

You can run the uptime command without any options like so:

It will display an output similar to:

In order of appearance, the command displays the current time as the 1st entry, up means that the system is running and it is displayed next to the total time for which the system has been running, the user count (number of logged on users), and lastly, the system load averages.

What are system load averages? It is the average number of processes that are in a runnable or uninterruptable state. A process is in a runnable state when it is using the CPU or waiting to use the CPU; while a process is in an uninterruptable state when it is waiting for I/O access like waiting for a disk.

To know more about uptime, check out our article: Understand Linux Load Averages and Monitor Performance of Linux

Now let’s see some useful uptime command usage with examples.

Check Linux Server Uptime

You can filter uptime’s result to show only the running time of the system with the command:

Check Linux Server Starting Time

Using option -s will display the date/time since when the system has been running.

Uptime Version & Help

As it is with most command line apps, you can display uptime’s version information and quick help page with the following command.

Having gotten to this point in the article, you can now use uptime for your daily runs and you’ll determine its level of usefulness to you. If you have any doubts, here’s its man page.
