![]() ![]() Thus, ps -e will display all of the processes. ![]() Let’s look at some of the Terminal commands you can use to list all running services in a SysV init system. 30 From the ps man page: -e Select all processes. Check all running services in a System V(SysV) init system In case you are using systemctl restart sshd start to start or stop a service, then you are using on a Systemd system. It was developed to speed up the boot process, managing dependencies, and much more. For instance, ps -ef will show all running processes, but if a process finishes, it is no longer returned by this command. It is the new init system that most Linux distros are moving to. We’ll take a closer look at some of the Bash utilities that can be used for this purpose. Upstart was initially developed for Ubuntu Linux distro to replace the old System V used in other older distributions. Overview In this tutorial, we’ll look at ways to get a list of programs that were started using the nohup command in Linux. Upstart init system was used to manage the start and stopping of services during boot, shutdown, and supervising them while the system is running. Use one of the three commands to list processes in Linux: ps displays a list of all processes it can also be used with options to get a more detailed output. It is an event-based init system which served as a replacement for the /sbin/init daemon. In case you are using /etc/init.d/sshd start to start or stop a service then you are using on a System V system. You can understand its strength and complexity. The ps command is an extensive tool and has over 80 command options. You can get information like process ID (PID) for the processes you or any other user is running on the same Linux system. SysV manages the startup process using shell script present in the /etc/init*. 34 You can get a list of python processes using pgrep: pgrep -lf python This, however, does not list the whole command line. The ps command in Linux displays running processes on the system. System V or commonly known as SysV is an old init system used by older Linux distributions and dates back to the original Unix. systemd, which is the latest init system as of writing this article.System V, which was the initial init system.System V(SysV) | Upstart | SystemdĪ lot of Linux distros fall under of the following init systems: For example, the Apache webserver service is httpd on CentOS and Apache2 on Ubuntu. Some service name varies from one distribution to another. ps -x PID TTY STAT TIME COMMAND 1080 Ss 0:00 /lib/systemd/systemd -user 1081 S 0:00. The service command references each service using the init script stored in /etc/init.d for Ubuntu and any other Debian-based distro, and etc/rc.d/init.d for RedHat-based Linux distributions. Use the ps command to list the running processes owned by you. ![]()
