.TH "htop" "1" "0.5" "Bartosz Fenski <fenio@o2.pl>" "Utils"
.SH "NAME"
htop \- interactive process viewer
.SH "SYNTAX"
.LP
.B htop
.SH "DESCRIPTION"
.LP
This program is a free (GPL) ncurses-based process viewer.
.LP
It is similar to top, but allows to scroll the list vertically and
horizontally to see all processes and their full command lines.
.LP
Tasks related to processes (killing, renicing) can be done without
entering their PIDs.
.br
.SH "INTERACTIVE COMMANDS"
.LP
The following commands are supported:
.LP
.TP 5
.B Arrows, PgUP, PgDn, Home, End
Scroll process list.
.TP
.B Space
"Tag": mark 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.
.TP
.B F1, h
Help screen
.TP
.B F2, S
Setup screen. There you can configure meters displayed on the top side
of the screen, as well as setting various display options.
.TP
.B F3, /
Incremental process search: type in part of a process command line and
the selection highlight will be moved to it. While in search mode,
pressing this key will cycle through matching occurrences.
.TP
.B F4, I
Invert sort order: if sort order is increasing, switch to decreasing,
and vice-versa.
.TP
.B 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.
.TP
.B Shift-F6 (F18), <
Select sorting by previous field. The sort field is indicated by a
highlight in the header.
.TP
.B F6, >
Select sorting by next field. The sort field is indicated by a
highlight in the header.
.TP
.B F7, ], -
Increase selected process priority (subtract from 'nice' value).
This can be done by the superuser only.
.TP
.B F8, [, +
Decrease selected process priority (add to 'nice' value)
.TP
.B 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.
.TP
.B F10, q
Quit
.TP
.B M
Sort by memory usage (top compatibility key).
.TP
.B P
Sort by processor usage (top compatibility key).
.TP
.B T
Sort by time (top compatibility key).
.TP
.B C
Select displayed columns.
.TP
.B 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.
.TP
.B U
Shadow other users: processes belonging to other users are displayed in
dim color (requires a capable terminal).
.TP
.B K
Hide kernel threads: prevent the threads belonging the kernel to be
displayed in the process list.
.TP
.B Ctrl-L
Refresh: redraw screen and recalculate values.
.TP
.B Numbers
PID search: type in process ID and the selection highlight will be moved to it.
.PD
.SH "AUTHORS"
