|
The \fI/proc\fR file system is used to obtain the process information.
|
|
|
|
|
Terminal names in \fI/dev\fR are used to generate the
|
2005-05-02 15:01:42 +02:00
|
|
|
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 .
