Qps is a visual process manager, 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.

Qps can:
* change nice value of a process
* alter the scheduling policy and soft realtime priority of a process
* display the TCP/UDP sockets used by a process, and names of the
connected hosts (Linux only)
* display the memory mappings of the process (which files and shared
libraries are loaded where)
* display the open files of a process, and the state of unix domain
sockets
* kill or send any other signal to selected processes
* display the load average as a graph, and use this as its icon when
iconified
* show (as graph or numbers) current CPU, memory and swap usage
* sort the process table on any attribute (size, cpu usage, owner etc)
* on SMP systems running Linux 2.1 or later (or Solaris), display cpu
usage for each processor, and which CPU a process is running on
* display the environment variables of any process
* show the process table in tree form, showing the parent-child
relationship
* execute user-defined commands on selected processes
* display MOSIX-specific fields and migrate processes to other nodes
in a cluster
