4. Technical Description
I'm sponsoring this fasttrack for myself.
I request Patch/Micro release binding (this change is compatible).
We currently ship two "ps" executables: /usr/bin/ps and /usr/ucb/ps.
Some people prefer "ps -ef" and others like "ps uxga".
It's fairly easy to unify the commands so that we do the "right thing".
We propose that the unified command works as follows:
If a first argument is present and it does not start with a "-" we run
as "/usr/ucb/ps"
If a first argument is present and it starts with "-" and some of the
characters passed aren't ucb ps options, we run as "/usr/bin/ps"
If neither are not the case, then ps will behave as before: /usr/ucb/ps
and /usr/bin/ps will both work as before, depending on the
getexecname() return value.
The /usr/ucb/*/ps binaries will be hardlinked to /usr/bin/*/ps.
They will stay in their respective packages.
The /usr/ucb/sparcv7/ps binary is removed; there is no /usr/bin/sparcv7/ps.
