htop - interactive process viewer - 交互式进程查看器

1. DESCRIPTION

Htop is a free (GPL) ncurses-based process viewer for Linux.
Htop 是 Linux 免费 (GPL) 的基于 ncurses 的进程查看器。

It is similar to top, but allows you to scroll vertically and horizontally, so you can see all the processes running on the system, along with their full command lines, as well as viewing them as a process tree, selecting multiple processes and acting on them all at once.
它与 top 类似，但是允许您垂直和水平滚动，因此您可以查看系统上运行的所有进程以及它们的完整命令行，以及将它们视为进程树，选择多个进程并对其进行操作。

Tasks related to processes (killing, renicing) can be done without entering their PIDs.
无需输入其 PID 即可完成与进程相关的任务 (killing, renicing)。

2. COLUMNS

The following columns can display data about each process. A value of - in all the rows indicates that a column is unsupported on your system, or currently unimplemented in htop. The names below are the ones used in the Available Columns section of the setup screen. If a different name is shown in htop’s main screen, it is shown below in parenthesis.
以下各列可以显示有关每个进程的数据。所有行中的值 - 表示系统上不支持该列，或者当前在 htop 中未实现该列。下面的名称是设置屏幕 Available Columns 部分中使用的名称。如果在 htop 的主屏幕中显示了其他名称，则该名称显示在下面的括号中。
