htop

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. 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. List of additional build-time dependencies (based on feature flags): pkg-config sensors hwloc libcap (v2.21 or later) libnl-3 and libnl-genl-3 pkg-config is optional but recommended. The configure script of htop might utilize pkg-config to obtain the compiler and linker flags required for a library. Some OS distributions provide pkg-config functionalities through an alternative implementation such as pkgconf . Look for both names in your package manager. Install these and other required packages for C development from your package manager. Compile from source: To compile from source, download from the Git repository ( git clone or downloads from GitHub releases), then run: ~~~ shell ./autogen.sh && ./configure && make ~~~ 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). htop checks for the availability of the actual runtime libraries as htop runs. More information on required and optional dependencies can be found in configure.ac. If you have trouble running htop please consult your operating system / Linux distribution documentation for getting support and filing bugs.
