List running processes in Linux

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.
• top – displays a live list of currently active processes and allows you to interact with them by killing, stopping, changing priority, and so on.
• htop – instantaneous results on a user-friendly output with the opportunity to engage with the process

Utilizing ps as a command

The ps command (process statuses) creates a snapshot of all currently active processes. As a result, unlike the Windows task manager, the outcomes are predictable.

The syntax for the ps command is as follows:

ps [options]

The following are some of the most commonly used ps command options:

• a: Make a list of all processes that are causing problems for all users.
• -A, -e: Display a list of all the processes on the system.
• -a: List all processes, excluding session leaders (those whose process ID is the same as the session * ID) and those not associated with a terminal.
• -d: Except for session leaders, list all processes.
• –deselect, - N: Remove any processes that do not meet a user-defined condition from the list.
• f: Uses ASCII art to display the process hierarchy.
• -j: Shows the output in jobs format.
• T: Make a list of all the processes that are connected to this terminal.
• r: Only list processes that are currently active.
• u: Increase the size of the output to include more information, such as CPU and memory use.
• -u: Define a user for whom you want to list processes.
• x: Processes without a TTY are included.

Running the ps command without any options produces an output similar to

The following categories are included in the default output:

• PID: Process Identification Number
• TTY: The terminal on which the process is operating.
• TIME: The total amount of time spent on the computer (CPU usage total amount).
• CMD: The name of the command that started the process

Using the a, u, and x options together produces a more detailed output

ps aux

The extended output now includes the following new categories:

• USER: This is the name of the person who is executing the process.
• %CPU: The proportion of time that the CPU is in use.
• %MEM: The proportion of memory used.
• VSZ: The process’s total virtual memory usage in kilobytes.
• RSS: “stands for Resident Set Size”, which refers to the amount of RAM used by a process.
• STAT: The current state of the process.
• START: The time when the process began.

To show the currently executing processes in a hierarchical order.

ps -axjf

Using the top command in Linux, you can get a list of currently running processes
