Normally only the caller's own processes are listed in short format (the PID, TTY, TIME and CMD fields as explained below). The long listing contains: ST State: R: runnable W: waiting (on a message) S: sleeping (i.e.,suspended on PM or VFS) Z: zombie T: stopped UID, PID, PPID, PGRP The user, process, parent process and process group ID's. SZ Size of the process in kilobytes. RECV Process/task on which a receiving process is waiting or sleeping. TTY Controlling tty for the process. TIME Process' cumulative (user + system) execution time. CMD Command line arguments of the process. The /proc file system is used to obtain the process information. Terminal names in /dev are used to generate the mnemonic names in the TTY column, so ps is independent of terminal naming conventions. NOTES The '-' option prefix is not required. For marginal compatibility with System V usage, the hidden option -e means the same as -ax, and -f is the same as -l. PS(1)
