This matches NetBSD, and also seems to be what linux does. The sentence
which is added to the man page is taken straight from NetBSD.

kvm_getprocs() will provide useful information if it can, or *it*
will provide a zero value if it can not find something appropriate.

Any [standard output] field need not be meaningful in all
implementations. In such a case a hyphen ('-') should be
output in place of the field value
So have the `-O label' option print out the string " -" if the

These new options are not documented yet. More options will be coming,
and I will update the man page after I get farther along.

sort-by-CPU or sort-by-memory will only calculate values once-per-process,
instead of twice-per-comparison. Also take advantage of this to simplify
the pscomp() routine.

are now errors (instead of being treated like `ps -p 0 -p 12').

Note that `ps t' is still changed to `ps -T', since that is one of
the main reasons for this kludge processing...

more special situations. This is the code which process `ps blah',
when "blah" does not include a leading '-'.
This change also removes a long-undocumented BACKWARD_COMPATIBILITY
compile-time option, where:
ps -options arg1 arg2
(with no '-' on "arg1" and "arg2") was treated as:
ps -options -N arg1 -M arg2
This also changes `ps' to check for any additional arguments after
processing all the '-'-options, and attempt to use those arguments as
a pid or pidlist. If an extra argument is not a valid pidlist, then
`ps' will print an error and exit. This seems a more generally useful
extension of the kludge-option processing than the -N/-M behavior, and
has fewer confusing side-effects.

those options are implemented in src/sys/kern/kern_proc.c (v1.203).

This corrects a problem of lost-precision for `-r' (sort-by-CPU). Also,
for sort-by-CPU and sort-by-memory, any processes which have the same
value CPU or MEMORY are now sorted by TTY and then (if needed) by pid.

My earlier attempt to fix this (v1.65) only seemed to work because of a
lucky random value in nentries (which was not being initialized back
when I tested that earlier patch).

- Change `-p' to allow a list of process IDs, and `-t' to allow a list
of terminal names, instead of only a single value for each.
- Add the `-A' option of SUSv3, which is exactly the same as `-ax'.
- Add the `-G gidlist' (group id).
- Allow any of these "selector options" to be specified multiple times,
and have `ps' keep adding to a given list -- instead of replacing the
previously-specified values.
- Fix interactions between selector-options, so that: "If any are
specified, ... ps shall select the processes represented by the
inclusive OR of all the selection-criteria options." (from SUSv3)
- Add a `-X' option, which is the reverse of the `-x' option.
- various minor improvements in parsing and error handling.
This does not get us to match POSIX/SUSv3, but it gets us closer. The
`-g pgidlist', `-R ruserlist' and `-s sidlist' options mentioned in
freebsd-standards are still under debate, so they skipped for now.
It should be true that this introduces no user-visible incompatible
changes, except to support "new stuff" that was not supported before.
