parameters by compiling `ps' with -DPS_BACKWARD_COMPATIBILITY=0, instead of requiring them to patch ps.c. The default behavior has not changed.

MFC *: Fix the kludge-old-options processing so `ps tpt' will be treated

the same as `ps -tpt', instead of being changed into `ps -tpT'. Also adjust it so `ps t p0' is treated like `ps -t p0', instead of making it `ps -T p0'. This includes the rewrite of the kludge-option processing, but it does NOT remove the long-undocumented BACKWARD_COMPATIBILITY compile-time option. If you delete the '#define BACKWARD_COMPATIBILITY' line, you'll get the newer handling for "extra arguments", which is to treat them as requests for processes. Also brings in a number of style(9) improvements. [* = 1.90 & 1.92 -> 1.98 ps.c] PR: bin/52489 (for `ps tpt' and `ps t p0') Submitted by: Jilles Tjoelker ( " )

MFC *: Change the #if-ish logic which is used to add the `-f' option

2004-04-04T17:50:23Z

when `ps' is compiled with LAZY_PS, so that there is only one PS_ARGS string to modify when changing the option-list. Also get `-f' to show up in the usage() statement when compiled with LAZY_PS. Also move the 'f' case in the select statement, so it in alphabetical order. [* = 1.68 1.69 & 1.86 ps.c] Approved by: re(scottl)

MFC *: Support more POSIX/SUSv3 options:

2004-04-04T17:03:40Z

- 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 should result in no user-visible changes, except for adding the new features. The man page is updated to describe the new features, and to describe the sorting options in better and more complete detail.

mainly to greatly reduce the code-diffs in ps.c (but that dragged in some similar changes to the other files). This should result in no user-visible changes. This is done to make it easier to MFC some user-visible changes that are coming up, but those MFC's will be done at a later date.
