- 1) No change to the general form of current syntax;- 2) Selection can be as presently: by number (index in cfdata), by name (driver name), but also (NEW) by pattern: a pattern is between slashes, it is a fix substring, that can be optionnally anchored at the beginning with `^' and at the end with `$'; - 3) (NEW) If the selector (will this word do?) in 2) is surrounded by braces `{' `}', the selector is for a group of devices; - 4) The STAR (existing) is still handled as a suffix. Examples: disable i915drmkms # existing syntax disable {drmkms} # NEW: disable devices belonging to group "drmkms" disable {/^drm/}* # NEW: disable devices belonging to groups # whose name begins with the substr "drm" if # they are STARred ones.
I think you can simplify things a bit by: 1) Allowing shell-like patterns (not hard to implement): uc> disable drm* # all starting with `drm' uc> disable *drm* *usb$ # all with `drm' anywhere and those ending in `usb' uc> disable foo # exact match `foo' uc> disable 1 # exact match 1 (index) 2) Having an alias facility: uc> alias drm_disable=disable i915*; disable *radeon*; ... uc> drm_disable # executes: RHS text (no recursive expansion) uc> alias drm_disable= # remove alias `drm_disable' -RVP
