htop is an improved version of top, a complex process viewer which allows to visualize processes in real time, see memory and CPU consumption, send signals to processes, renice processes, and sort them by various options. It makes use of colors and you can also scroll horizontally and vertically to see the full names of the running processes.

All modern operating systems are able to run many programs at the same time. For example, a typical Linux server might include a Web server, an email server, and probably a database service. Each of these programs runs as a separate process. What do you do if one of your services stops working? Here are some handy command-line tools for managing processes.

Qps Visual Process Manager is an X11 version of “top” or “ps” that displays processes in a window and lets you sort and manipulate them. It displays some general system information, and many details about current processes (such as the TCP/UDP sockets in use by a process). Qps runs on Linux and Solaris.

One of the things I hate about Windows is that there is no good way to kill frozen processes. Theoretically, you type Ctrl-Alt-Delete, wait for Task Manager to pop up, and kill the process. But in reality, the process doesn't always die immediately (it usually takes multiple tries and a very long time). GNU/Linux users don't have this problem.

Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. At the core of an operating system is the kernel. The kernel is the most fundamental program on the computer: It does all the basic housekeeping and lets you start other programs.

The PSMon utility lets you specify which processes should be running, how much of resources such as CPU or RAM each is allowed to use when it runs, and how many instances are able to be run. PSMon will then ensure that these processes are running and kill off a process if it starts to use too many resources, and possibly restart a process if it has crashed.

Ninja is a privilege escalation detection  and  prevention system for GNU/Linux hosts.

Your GNU/Linux computer is an amazing machine. It can display images. It can run programs. It can perform dozens of functions all at the same time. How can you keep track of all this activity? By monitoring the processes that your computer runs, and one of the best ways to monitor and control processes is by using the command line.

Bradley Kuhn grumbles about Black Duck Software's recently-announced patent on the process of finding license incompatibilities. "Indeed, the process described is so simple-minded, that it's a waste of time in my view to spend time writing a software system to do it.
