htop - an interactive process viewer for Unix #ril
- This is htop, an interactive process viewer for Unix systems. It is a text-mode application (for console or X terminals) and requires ncurses.
- Since version 2.0, htop is now cross-platform!

FOSDEM 2016 - Going cross-platform - how htop was made portable 一開始只是 linux-only，後來才走向 portable；雖然 UI 用 ncurses (portable)，但在蒐集 process data 這一塊則是基於
/procfilesystem。 -
- Users often deploy htop in cases where Unix top does not provide enough information about the system's processes. htop is also popularly used interactively as a SYSTEM MONITOR. Compared to top, it provides a more convenient, visual, cursor-controlled interface for SENDING SIGNALS TO PROCESSES. 難怪除了 process-viewer，也是 process-manager。
- htop is written in the C programming language using the ncurses library. Its name is derived from the original author's first name, as a nod to pinfo, an info-replacement program that does the same. 就像取代 info 的 pinfo 中的 p 來自作者名字的 "P"rzemek Borys，所以取代 top 的 htop，它的 p 也是來自作者名字的 "H"isham Muhammad。
- Cross-platform, OpenBSD, FreeBSD and Mac OS X, support was added in htop 2.0. Solaris/Illumos/OpenIndiana support added in 2.2.0.
