интерактивный просмотрщик процессов (interactive process viewer)
Интерактивные команды (Interactive commands)
The following commands are supported while in htop:
Up, Alt-k
Select (highlight) the previous process in the process list.
Scroll the list if necessary.
Down, Alt-j
Select (highlight) the next process in the process list.
Scroll the list if necessary.
Left, Alt-h
Scroll the process list left.
Right, Alt-l
Scroll the process list right.
PgUp, PgDn
Scroll the process list up or down one window.
Home Scroll to the top of the process list and select the first
process.
End Scroll to the bottom of the process list and select the last
process.
Ctrl-A, ^
Scroll left to the beginning of the process entry (i.e.
beginning of line).
Ctrl-E, $
Scroll right to the end of the process entry (i.e. end of
line).
Space
Tag or untag a process. Commands that can operate on
multiple processes, like "kill", will then apply over the
list of tagged processes, instead of the currently
highlighted one.
c Tag the current process and its children. Commands that can
operate on multiple processes, like "kill", will then apply
over the list of tagged processes, instead of the currently
highlighted one.
U Untag all processes (remove all tags added with the Space or
c keys).
s Trace process system calls: if strace(1) is installed,
pressing this key will attach it to the currently selected
process, presenting a live update of system calls issued by
the process.
l Display open files for a process: if lsof(1) is installed,
pressing this key will display the list of file descriptors
opened by the process.
w Display the command line of the selected process in a
separate screen, wrapped onto multiple lines as needed.
x Display the active file locks of the selected process in a
separate screen.
F1, h, ?
Go to the help screen
F2, S
Go to the setup screen, where you can configure the meters
displayed at the top of the screen, set various display
options, choose among color schemes, and select which
columns are displayed, in which order.
F3, /
Incrementally search the command lines of all the displayed
processes. The currently selected (highlighted) command will
update as you type. While in search mode, pressing F3 will
cycle through matching occurrences. Pressing Shift-F3 will
cycle backwards.
Alternatively the search can be started by simply typing the
command you are looking for, although for the first
character normal key bindings take precedence.
F4, \
Incremental process filtering: type in part of a process
command line and only processes whose names match will be
shown. To cancel filtering, enter the Filter option again
and press Esc.
F5, t
Tree view: organize processes by parenthood, and layout the
relations between them as a tree. Toggling the key will
switch between tree and your previously selected sort view.
Selecting a sort view will exit tree view.
F6, <, >
Selects a field for sorting, also accessible through < and
>. The current sort field is indicated by a highlight in
the header.
F7, ]
Increase the selected process's priority (subtract from
'nice' value). This can only be done by the superuser.
F8, [
Decrease the selected process's priority (add to 'nice'
value)
Shift-F7, }
Increase the selected process's autogroup priority (subtract
from autogroup 'nice' value). This can only be done by the
superuser.
Shift-F8, {
Decrease the selected process's autogroup priority (add to
autogroup 'nice' value)
F9, k
"Kill" process: sends a signal which is selected in a menu,
to one or a group of processes. If processes were tagged,
sends the signal to all tagged processes. If none is
tagged, sends to the currently selected process.
F10, q
Quit
I Invert the sort order: if sort order is increasing, switch
to decreasing, and vice-versa.
+, -, *
When in tree view mode, expand or collapse subtree. When a
subtree is collapsed a "+" sign shows to the left of the
process name. Pressing "*" will expand or collapse all
children of PIDs without parents, so typically PID 1 (init)
and PID 2 (kthreadd on Linux, if kernel threads are shown).
a (on multiprocessor machines)
Set CPU affinity: mark which CPUs a process is allowed to
use.
u Show only processes owned by a specified user.
N Sort by PID.
M Sort by memory usage (top compatibility key).
P Sort by processor usage (top compatibility key).
T Sort by time (top compatibility key).
F "Follow" process: if the sort order causes the currently
selected process to move in the list, make the selection bar
follow it. This is useful for monitoring a process: this
way, you can keep a process always visible on screen. When a
movement key is used, "follow" loses effect.
K Hide kernel threads: prevent the threads belonging the
kernel to be displayed in the process list. (This is a
toggle key.)
H Hide user threads: on systems that represent them
differently than ordinary processes (such as recent NPTL-
based systems), this can hide threads from userspace
processes in the process list. (This is a toggle key.)
p Show full paths to running programs, where applicable. (This
is a toggle key.)
Z Pause/resume process updates.
m Merge exe, comm and cmdline, where applicable. (This is a
toggle key.)
Ctrl-L
Refresh: redraw screen and recalculate values.
Numbers
PID search: type in process ID and the selection highlight
will be moved to it.
