pstool is a CLI program whose purpose is to list the loaded processes in a Linux or Windows based system and to give detailed information about each one of them, such as the process ID, executable name, command line parameters with which the process was started, and the network or Internet connections of the process if any. The program can show the information for a specific process or group of processes of a program, giving you the ability to search by name, PID (process ID), or process status. pstool has an option for a verbose results.

[UPDATE] 2025-05-02: (v.2025.3) Cleaning some differences between Linux and Windows versions, like the keyword for "net_connections", which was "connections" with previous versions of psutil library. Changed the way of how the total number of loaded processes is displayed if pstool is used without additional command line arguments. In Linux version the total amount of used memory is currently not displayed along with the number of loaded processes.

Usage: $pstool -> list all the loaded processes

Optional arguments:

  --name NAME                                            process name
  --status {running,stopped,sleeping,zombie,dead,idle}   process status
  --pid PID                                              process PID
  -v                                                     show verbose results

The current version of pstool can also terminate a single process or all loaded processes of a given program. The following optional arguments are related to process(es) termination:

  --kill PID [PID ...]        terminate process(es)
  --killall NAME [NAME ...]   terminate process(es) by name
