*How to Check System Uptime in Linux*
Welcome back to our channel! In today's tutorial, we’ll be showing you various methods to check your system’s uptime in Linux. Uptime is the amount of time your system has been running since its last reboot. This can be useful for monitoring system performance, troubleshooting, and ensuring your system's stability.
*Method 1: Using the `uptime` Command*
The simplest way to check system uptime is by using the `uptime` command. Open your terminal (you can use `Ctrl + Alt + T`), and type:
```bash
uptime
```
This will output something like:
```
10:14:32 up 1 day, 2:03, 3 users, load average: 0.15, 0.10, 0.08
```
Here's what this means:
- `10:14:32`: The current time.
- `up 1 day, 2:03`: The system has been up for 1 day and 2 hours and 3 minutes.
- `3 users`: The number of users currently logged in.
- `load average: 0.15, 0.10, 0.08`: The system load averages for the past 1, 5, and 15 minutes.
*Method 2: Using the `top` Command*
The `top` command provides a dynamic real-time view of your system, including uptime. Simply type:
```bash
top
```
At the top of the output, you’ll see the uptime in a format similar to the `uptime` command.
*Method 3: Using the `who` Command*
The `who` command with the `-b` option will show you the last boot time, from which you can calculate uptime:
```bash
who -b
```
This will output something like:
```
system boot 2024-07-20 08:20
```
*Method 4: Using the `/proc/uptime` File*
The `/proc/uptime` file contains the system uptime in seconds. You can view it by typing:
```bash
cat /proc/uptime
```
This will output something like:
```
102405.67 234567.89
```
The first number is the total number of seconds the system has been up, and the second number is the amount of time spent in idle process.
To convert the seconds to a more readable format, you can use the following command:
```bash
awk '{printf("Uptime: %d days, %02d:%02d:%02d\n", $1/86400, ($1%86400)/3600, ($1%3600)/60, $1%60)}' /proc/uptime
```
*Method 5: Using the `w` Command*
The `w` command shows who is logged on and what they are doing, along with the system uptime:
```bash
w
```
The output includes the current time, system uptime, number of users logged in, and the load averages.
*Conclusion:*
These are some of the most common methods to check your system's uptime in Linux. Depending on your preference and the level of detail you need, you can choose any of these methods.
