12: .I Ps
13: prints information about processes.
14: Normally, only the user's
15: non-shell processes are reported.
16: .PP
17: All output formats include, for each process, the process id, its
18: control terminal, status, cpu time, and command.
19: The status is given
20: by a sequence of letters:
21: .ta \w'W'u+1m \n(LLu/2u +\w'W'u+1m
22: .PP
23: \f5R\f1 Running. \f5T\f1 Stopped.

41: .TP \n(xx
42: .B a
43: Give information about all users (ordinarily
44: only one's own processes are displayed).
45: .PD 0
46: .TP
47: .BI F file
48: Display all processes having the
49: .IR file
50: open;
51: this option must be the last in a cluster.
52: .TP
53: .B f

64: resident set size, parent process id, and wait channel.
65: .TP
66: .B n
67: Print unsorted
68: (output is normally sorted by process id).
69: .TP
70: .B r
71: Print processes which match the current real or effective user id
72: (normally only processes matching the current effective user id
73: are printed).
74: .TP
75: .BI t s
76: Print processes whose control stream is
77: .I s,
78: where
79: .I s
80: is either
81: .L .
82: (for user's tty), or one of the forms printed by

91: for
92: .FR /dev/dk/dk12 ,
93: .L t?
94: for processes with no tty, etc.
95: This option must be the last in a cluster.
96: .TP
