## 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.
|
|
Also system wide information, like load average or swap usage, is shown.
|
|
|
|
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 libncurses(w).
|
|
|
|
`htop` is written in C.
|

## Build instructions
|
|
|
|
### Prerequisite
|
|
List of build-time dependencies:
|
|
* standard GNU autotools-based C toolchain
|
|
- C99 compliant compiler
|
|
- `autoconf`
|
|
- `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` (v2.21 or later)
|
|
* `libnl-3`
|
|
|
|
Install these and other required packages for C development from your package manager.
|
|
|
|
**Debian/Ubuntu**
|
|
~~~ shell
|
|
sudo apt install libncursesw5-dev autotools-dev autoconf build-essential
|
|
~~~
|
|
|
|
**Fedora/RHEL**
|
|
~~~ shell
|
|
sudo dnf install ncurses-devel automake autoconf gcc
|
|
~~~
|
|
|
|
**Archlinux/Manjaro**
|
|
~~~ shell
|
|
sudo pacman -S ncurses automake autoconf gcc
|
|
~~~
|
|
|
|
### Compile from source:
|
|
To compile from source, download from the Git repository (`git clone` or downloads from [GitHub releases](https://github.com/htop-dev/htop/releases/)), then run:
|
|
~~~ shell
|
|
./autogen.sh && ./configure && make
|
|
~~~
|
|
|
|
### 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-affinity`:
|
|
enable `sched_setaffinity(2)` and `sched_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*
|
|
|
|
#### Performance Co-Pilot
|
|
|
|
* `--enable-pcp`:
|
|
enable Performance Co-Pilot support via a new pcp-htop utility
|
|
- dependency: *libpcp*
|
|
- default: *no*
|
|
|
|
#### Linux
|
|
|
|
* `--enable-sensors`:
|
|
enable libsensors(3) support for reading temperature data
|
|
- dependencies: *libsensors-dev*(build-time), at runtime *libsensors* is loaded via `dlopen(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:
|
|
|
|
#### Linux
|
|
* `libdl`, if not building a static binary, is always required when support for optional dependencies (i.e. `libsensors`, `libsystemd`) is present.
|
|
* `libcap`, user-space interfaces to POSIX 1003.1e capabilities, is always required when `--enable-capabilities` was used to configure `htop`.
|
|
* `libsensors`, readout of temperatures and CPU speeds, is optional even when `--enable-sensors` was used to configure `htop`.
|
|
* `libsystemd` is optional when `--enable-static` was not used to configure `htop`. If building statically and `libsystemd` is not found by `configure`, support for the systemd meter is disabled entirely.
|
|
|
|
`htop` checks for the availability of the actual runtime libraries as `htop` runs.
|
|
|
|
#### BSD
|
|
On most BSD systems `kvm` is a requirement to read kernel information.
|
|
|
|
More information on required and optional dependencies can be found in [configure.ac](configure.ac).
|
|
|
|
## Usage
|
|
See the manual page (`man htop`) or the help menu (**F1** or **h** inside `htop`) for a list of supported key commands.

## History
|
|
|
|
`htop` was invented, developed and maintained by [Hisham Muhammad](https://hisham.hm/) from 2004 to 2019. His [legacy repository](https://github.com/hishamhm/htop/) has been archived to preserve the history.
|
|
|
|
In 2020 a [team](https://github.com/orgs/htop-dev/people) took over the development amicably and continues to maintain `htop` collaboratively.
