![]() Another way to do this is to use the systemctl command, which will show the current status of all services on the system. a: List processes from all users u: List the usernames as well x: Include processes without an attached or controlling terminal. The most common way to do this is to use the ps command, which will list all the running processes on the system. nmon - a system monitor tool for the AIX and Linux operating systems. Checking running services in Linux can be done in a few different ways.ps -ef lists all processes ps aux lists all processes in alternative format (BSD) This can be used to check if a given application is running. Both list all processes running by all users, though they differ in the format they output (the reason for the differences are historical). If you want to see all of the background processes running on the system, you can use ps -e, or ps -eF to get some additional details. There are two common ways to list all processes on a system. "ps auxww" provides complete information about the process, including all parameters. The jobs command will show any background jobs started within the current shell, usually by starting a background task with the & operator or Z bg (e.g. For maximum compatibility, there is no "-" in front of the "aux". (For example, the "e" or "-e" option will display environment variables.) On such systems, ps commonly runs with the non-standard options aux, where "a" lists all processes on a terminal, including those of other users, "x" lists all processes without controlling terminals and "u" adds a column for the controlling user for each process. Most systems derived from BSD fail to accept the SUS and POSIX standard options because of historical conflicts. Another common option on these systems is -l, which specifies the " long" output format. ![]() On operating systems that support the SUS and POSIX standards, ps commonly runs with the options -ef, where "-e" selects every process and "-f" chooses the " full" output format. ![]() Memory address of the event the process is waiting for The amount of CPU time used by the process ID number of the process's parent process Name of the process, including arguments, if any Alternatively, you can issue the top command or htop command to view running process in Linux.
