Knowing the PID and PPID of a process can be helpful if you need to manage or interact with a process running on your system. There are numerous ways to get the PID (Process ID) and PPID (Parent Process ID) of a given process in Linux. I'll explain these commands in detail but bef...
In this guide, we explored how to identify and manage bad sectors on Linux drives using badblocks and smartmontools. Keeping tabs on your storage health is crucial—and these tools make it pretty straightforward. If you have any questions, feedback, or suggestions, feel free to reach out in...
While listing the active processes in the background, it may not show the name of the process and will only show you the PID of the process. And if you are curious to know the name of the process, then you can use the ps command in the following manner: ps -p <Enter_PID> -o c...
In addition to monitoring, you can interact with the process list using various keyboard shortcuts, including:k –terminate a process. r –adjust the priority of a process. m –sort processes by memory usage. n – sort processes by PID. d –change the refresh time interval. h –see the...
To find out how long a process (program or application) has been running, open a terminal and type the following command: ps -eo pid,comm,etime List Process Running Time in Linux This command lists theprocess ID (PID), command name, and elapsed time (etime) for all processes. The elaps...
Similarly, use -c to only return process ids that are running with the same root directory. This option is ignored for non-root users, as they will be unable to check the current root directory of processes they do not own. Other commands can also be used to find the pid of the proce...
So, you just learned how to find process name from its PID in Linux command line and you also learned to get the PID from the process name. If something isn't working right, or you just have any comments in general, feel free to leave any of it in the comments below....
To disable a service, so the service will not start automatically at boot time, run: $sudosystemctl disable sshd Wrap up Not everything usessystemctlby default. Some applications are intended to be started manually. Of course, you can always add your own systemd service files when you need...
To use a time zone other than the system default for just one shell session, set the TZ environment variable to the name of a file in /usr/share/ zoneinfo and test the change, like this: 要在仅对一个shell会话使用非系统默认时区,请将TZ环境变量设置为/usr/share/zoneinfo中的文件名,并测试...
One way would to be check the process with PID 1 (after all, an init system is the first process to run on a Linux system). ps 1 But its output could be misleading as often it shows/sbin/initwhich is just a soft link to actual init process. ...
