|
|
.PP

|
|
.PP
|
|
TTY
|
|
Controlling tty for the process.
|
|
.PP
|
|
TIME
|
|

.PP
|
|
The files \fI/dev/{mem,kmem}\fR are used to read the system tables and command
|
|
line arguments from. Terminal names in \fI/dev\fR are used to generate the
|
|
mnemonic names in the TTY column, so \fIps\fR is independent of terminal naming
|
|
conventions.
|
|
.SH NOTES
|
|
The '\-' option prefix is not required.
|
|
For marginal compatibility with System V usage, the hidden option
|
|
.B \-e
|
|
means the same as
|
|
.BR \-ax ,
|
|
and
|
|
.B \-f
|
|
is the same as
|
|
.BR \-l .
