Process Manager

Find a running app and end it, or force it to end when it does not stop. Apps are grouped by name, with the CPU and memory they use right now.

Requirements

Command	Needed	What for
ps	Required	Lists the processes, with their owner and command line.
kill	Required	Ends a process.
sh	Required	Reads every process in one go, with awk and cat. They come with every Linux system.
getconf	Required	Finds the clock rate and page size, to turn the kernel's numbers into CPU and memory. It comes with every Linux system.
pkexec	Required	Ends another user's process, after asking for an administrator's password. Without it, those cannot be ended.
sudo	Optional	Ends another user's process in a terminal, when End as admin with is set to it.

Usage

Add the Process Manager widget to the bar and click it.

• Search by name, command line, user or process ID, and sort by CPU, memory or name.
• Each row is an app with how many processes it has. Open it to see each process.
• ✕ asks the app or process to end, so it can save and close. When it is still running 3 seconds later, the skull, Force end, stops it at once, without saving.
• A process that belongs to another user, such as root, shows a shield, End as admin, which asks for a password.
• The list scrolls through every app.
• Only your own processes show, unless All users is on.
• A process waiting on a disk or device, or one that already ended and waits for its parent, says so: neither can be ended until that changes.

Settings

Setting	Type	Default	Description
interval	int	2000	How often the list updates while the panel is open, in milliseconds, from 250 to 10000.
admin	select	pkexec	Advanced. How to end another user's process: pkexec, which needs a polkit agent, or sudo in a terminal.

Notes

• Processes are read only while the panel is open, from /proc and ps.
• CPU is the use since the last read, where 100% is one core, as top shows it.
• System totals are not shown here: Noctalia's system monitor shows them.
