前言
htop是一个linux下的实时的线程监控工具，htop提供了以下工具：
- In htop you can scroll vertically to view the full process list, and scroll horizontally to view the full command lines.
- It starts very quickly as compared top, because it doesn’t wait to fetch data during startup.
- In htop you can kill more than one processes at once without inserting their PIDs.
- In htop you no longer needed to enter process number or priority value to re-nice a process.
- Press “e” to print the set of environment variables for a process.
- Use mouse to select list items.
