![]() ![]() Check the last reboot time with uptime command in Linux To get the last shutdown time, we can run last shutdown|head -2. This command also lists the system shutdown time and reboot time. It searches back through the file /var/log/wtmp and displays a list of all users logged in (and out) since that file was created. ![]() ![]() The last command by default will show you a list of all the users who have logged in and out of the system. To list the last reboot time, run last reboot| head -2. It will show all reboots since the log file was created. The best way to check the last reboot time in Linux is using the last reboot command. Let’s get started! Check the last reboot time with last command in Linux We will be using the terminal commands “last,” “who -b,” “uptime -s,” and “dmesg” to obtain this information. This information can be useful for troubleshooting purposes, or simply to keep track of how often your system is being rebooted. The man command is the perfect documentation for Linux nerds.In this blog post, we will be discussing four different ways to check the last time your Linux system was rebooted. Also, as a programmer working on Linux, you can use the ideas in the programming snippets here to implement in your code.Īnd lastly, if you wish to know more about any of the commands mentioned about, just type in man. That brings us to the end of this article! Without a GUI, Linux allows us to perform a system restart in various ways that we’ve seen here today. c_str() – The function converts the string to char*, which is the required argument for system() function.Īpart from the above two functions, the C++ code follows the procedure used in the Python script.system() – The C/C++ function used to send commands from code to the Linux terminal.The process of restarting Linux using C++ is almost similar to the above procedure. The key thing to note here is that, the Python script eventually performs the shutdown command discussed previously.Īt the end of the Python script, the user is asked whether the shutdown request is to be cancelled or not.Ĭhoice = input("Do you want to cancel? (Y/N) : ") After we have all the information, we use system() function for relaying the command to the terminal for proper execution. Minutes = int(input("Enter number of minutes: "))įirstly, the code does some sanity checks on the input and then it accepts an integer for the number of minutes the shutdown is to be delayed. If len(choice) = 1 and (choice.upper() = 'P' or choice.upper() = 'R'): ![]()
