Process Widget

The process widget displays a table containing information regarding a running process, along with sorting, searching, and process control features.

Features

The process widget has three main components:

• The main process table
• The search sub-widget (opened with ++ctrl+f++ or ++slash++)
• The sort menu sub-widget (opened with ++s++ or ++f6++)

By default, the main process table displays the following information for each process:

• PID
• Name of the process
• CPU use percentage (note this is averaged out per available thread)
• Memory use percentage
• Reads per second
• Writes per second
• Total amount read
• Total amount written
• User
• State

Sorting

The table can be sorted by clicking on the table headers, which will either sort the table by that column, or if already sorting by that column, reverse the sorting order.

Alternatively, one can sort using the sort menu sub-widget, which is brought up using ++s++ or ++f6++, and can be controlled by arrow keys or the mouse.

Grouping

Pressing ++tab++ in the table will group entries with the same name together. The PID column will be replaced with the number of entries in each group, and usage is added together when displayed.

Note that the process state and user columns are disabled in this mode.

Process termination

Pressing ++d+d++ or ++f9++ will allow you to terminate the currently selected process/process group. On Unix-like operating systems, you are also able to control which specific signals to send (e.g. SIGKILL, SIGTERM).

If you're on Windows, or if the disable_advanced_kill flag is set in the options or command-line, then a simpler termination screen will be shown to confirm whether you want to kill that process/process group.

Tree mode

Pressing ++t++ or ++f5++ in the table toggles tree mode in the process widget, displaying processes in regards to their parent-child process relationships.

A process in tree mode can also be "collapsed", hiding its children and any descendants, using either the ++minus++ or ++plus++ keys, or double clicking on an entry.

Lastly, note that in tree mode, processes cannot be grouped together due to the behaviour of the two modes somewhat clashing.

Full command

You can show the full command instead of just the process name by pressing ++P++.

Search

Pressing ++slash++ or ++ctrl+f++ will open up the search sub-widget. By default, just typing in something will search by the process name.

This search can be further enhanced by matching by case, matching the entire word, or by regex.

We are able to also search for multiple things/conditions.

And if our search uses a keyword, we need to use quotation marks around the term to properly search it.

Lastly, we can refine our search even further based on the other columns, like PID, CPU usage, etc., as well as grouping together conditions.

You can also paste search queries (e.g. ++shift+insert++, ++ctrl+shift+v++).

Keywords

Note all keywords are case-insensitive. To search for a process/command that collides with a keyword, surround the term with quotes (e.x. "cpu").

Keywords	Example	Description
	btm	Matches by process or command name; supports regex
pid	pid=1044	Matches by PID; supports regex
cpu cpu%	cpu > 0.5	Matches the CPU column; supports comparison operators
memb	memb > 1000 b	Matches the memory column in terms of bytes; supports comparison operators
mem mem%	mem < 0.5	Matches the memory column in terms of percent; supports comparison operators
read r/s	read = 1 mb	Matches the read/s column in terms of bytes; supports comparison operators
write w/s	write >= 1 kb	Matches the write/s column in terms of bytes; supports comparison operators
tread t.read	tread <= 1024 gb	Matches he total read column in terms of bytes; supports comparison operators
twrite t.write	twrite > 1024 tb	Matches the total write column in terms of bytes; supports comparison operators
user	user=root	Matches by user; supports regex
state	state=running	Matches by state; supports regex
()	(<COND 1> AND <COND 2>) OR <COND 3>	Group together a condition

Comparison operators

Keywords	Description
=	Checks if the values are equal
>	Checks if the left value is strictly greater than the right
<	Checks if the left value is strictly less than the right
>=	Checks if the left value is greater than or equal to the right
<=	Checks if the left value is less than or equal to the right

Logical operators

Note all operators are case-insensitive, and the and operator takes precedence over the or operator.

Keywords	Usage	Description
and && <Space>	<COND 1> and <COND 2> <COND 1> && <COND 2> <COND 1> <COND 2>	Requires both conditions to be true to match
or ||	<COND 1> or <COND 2> <COND 1> &#124;&#124; <COND 2>	Requires at least one condition to be true to match

Units

All units are case-insensitive.

Keywords	Description
B	Bytes
KB	Kilobytes
MB	Megabytes
GB	Gigabytes
TB	Terabytes
KiB	Kibibytes
MiB	Mebibytes
GiB	Gibibytes
TiB	Tebibytes
