+## Name
+
+ps - list currently running processes
+
+## Synopsis
+
+```**sh
+$ ps [--version] [-e] [-f] [-q pid-list]
+```
+
+## Description
+
+Print a list of currently running processes in the current TTY.
+For each process, print its PID (process ID), to which TTY it belongs, and invoking commandline (CMD).
+
+## Options
+
+* `-e`: Consider all processes, not just those in the current TTY.
+* `-f`: Also print for each process: UID (as resolved username), PPID (parent PID), and STATE (Runnable, Sleeping, Selecting, Reading, etc.)
+* `-q pid-list`: Only consider the given PIDs, if they exist.
+
+## Examples
+
+```sh
+$ ps -ef
+```
