Introduction
htop
is a cross-platform interactive process viewer.
htop
allows scrolling the list of processes vertically and horizontally to see their full command lines and related information like memory and CPU consumption.
The information displayed is configurable through a graphical setup and can be sorted and filtered interactively.
Tasks related to processes (e.g. killing and renicing) can be done without entering their PIDs.
Running htop
requires ncurses
libraries (typically named libncursesw*).
For more information and details on how to contribute to htop
visit htop.dev.
Build instructions
Prerequisite
List of build-time dependencies:
build-essential
standard GNU autotools-basedautoconf
autotools
ncurses
Note about ncurses
:
htop requires ncurses 6.0. Be aware the appropriate package is sometimes still called libncurses5 (on Debian/Ubuntu). Also ncurses usually comes in two flavours:
- With Unicode support.
- Without Unicode support.
This is also something that is reflected in the package name on Debian/Ubuntu (via the additional 'w' - 'w'ide character support).
List of additional build-time dependencies (based on feature flags):
sensors
hwloc
libcap
Compiling htop
requires the header files for ncurses
. Install these and other required packages for C development from your package manager.
Debian/Ubuntu
sudo apt install libncursesw5-dev autotools-dev autoconf
Fedora/RHEL
sudo dnf install ncurses-devel automake autoconf
Compiling from source:
To compile from sources downloaded from the Git repository (git clone
or downloads from Github releases), then run:
./autogen.sh && ./configure && make
By default make install
will install into /usr/local
, for changing the path use ./configure --prefix=/some/path
.
Install
To install on the local system run make install
. By default make install
installs into /usr/local
. To change this path use ./configure --prefix=/some/path
.
Build Options
htop
has several build-time options to enable/disable additional features.
Generic
--enable-unicode
: enable Unicode support dependency: libncursesw default: yes--enable-pcp
: enable Performance Co-Pilot support via a new pcp-htop utility dependency: libpcp default: no--enable-affinity
: enablesched_setaffinity(2)
andsched_getaffinity(2)
for affinity support; conflicts with hwloc default: check--enable-hwloc
: enable hwloc support for CPU affinity; disables affinity support dependency: libhwloc default: no--enable-static
: build a static htop binary; hwloc and delay accounting are not supported default: no--enable-debug
: Enable asserts and internal sanity checks; implies a performance penalty default: no
Linux
--enable-sensors
: enable libsensors(3) support for reading temperature data dependencies: libsensors-dev(build-time), at runtime libsensors is loaded viadlopen(3)
if available default: check--enable-capabilities
: enable Linux capabilities support dependency: libcap default: check--with-proc
: location of a Linux-compatible proc filesystem default: /proc--enable-openvz
: enable OpenVZ support default: no--enable-vserver
: enable VServer support default: no--enable-ancient-vserver
: enable ancient VServer support (implies--enable-vserver
) default: no--enable-delayacct
: enable Linux delay accounting support dependencies: pkg-config(build-time), libnl-3 and libnl-genl-3 default: check
Runtime dependencies:
htop
has a set of fixed minimum runtime dependencies, which is kept as minimal as possible:
ncurses
libraries for terminal handling (wide character support).
Runtime optional dependencies:
htop
has a set of fixed optional dependencies, depending on build/configure option used:
libdl
, if not building static and support for some of the optional libraries is enabled, is always required when support for to optionally load dependencies (i.e.libsensors
,systemd
) is present.libcap
, user-space interfaces to the POSIX 1003.1e, is always required when--enable-capabilities
was used to configurehtop
.libsensors
, readout of temperatures and CPU speeds, is optional even when--enable-sensors
was used to configurehtop
.systemd
is optional when--enable-static
was not used to configurehtop
(Linux only). If building statically andlibsystemd
is not found byconfigure
support for the SystemD meter is disabled entirely.
htop
checks for the availability of the actual runtime lib as htop
runs.
BSD
On most *BSD systems you also have kvm
as a static requirement to read all the kernel information.
More information on required and optional dependencies can be found in configure.ac.
Usage
See the manual page (man htop
) or the on-line help ('F1' or 'h' inside htop
) for a list of supported key commands.
Support
If you have trouble running htop
please consult your Operating System / Linux distribution documentation for getting support and filing bugs.
Bugs, development feedback
We have a development mailing list. Feel free to subscribe for release announcements or asking questions on the development of htop.
You can also join our IRC channel #htop on Libera.Chat and talk to the developers there.
If you have found an issue with the source of htop, please check whether this has already been reported in our Github issue tracker. If not, please file a new issue describing the problem you have found, the location in the source code you are referring to and a possible fix.
History
htop
was invented, developed and maintained by Hisham Muhammad from 2004 to 2019. His legacy repository has been archived to preserve the history.
In 2020 a team took over the development amicably and continues to maintain htop
collaboratively.
