3 Ways to Check System Uptime on Linux Terminal

Checking Linux System Uptime

• 💡 The uptime command is the most common and straightforward way to check how long your Linux system has been running.
• 🎯 It displays the current time, system uptime (e.g., 49 minutes), and the number of logged-in users.

Understanding /proc/uptime

• 💻 Accessing the /proc/uptime file provides two key numbers: total system uptime in seconds and total CPU idle time in seconds.
• 📊 To convert the total uptime from seconds to minutes or hours, divide the first number by 60 (for minutes) or 3600 (for hours).

Determining Last Boot Time

• 🚀 The who -b command can show the last boot time of your system.
• ⚠️ Note: On virtual machines, this command might display the VM creation time instead of the system boot time, as demonstrated in the video.

Conclusion

• ✅ These three methods offer simple yet effective ways to monitor your Linux system's uptime and last boot time.
