Just to make sure we are talking about the same thing (and avoid "x/y
problem"):

Are you asking about adding *new* features (e.g, "rm --depth-first"
or "cat --expand-tabs"), and then about controlling them throught
a global configuration file?

That is, asking for two different things (new features, and new control 
options) ?

For example,
If there was an "rm --depth-first" feature,
you could enable it easily with "alias" - right?



If this is the case, I think it is best to explicitly separate it into
some very different requests:

1. The ability to control existing command-line features
through a global configuration file.
2. Adding "rm --depth-first" option
3. Adding "--expand-tabs" option to multiple programs.

As for #1 - this idea is the topic of the current thread,
and was previously decided to not be accepted.

As for #2 - not sure if this was discussed before,
but I have a hunch that once more sophisticated control
over file-traversal is needed, find(1) is likely better
solution (e.g. "find -depth").

As for #3 - The "expand" program already does tab-expansion.
It can be easily combined with existing programs using
a simple shell function.
e.g.:

   sorttab(){ sort "$@" | expand -t20 ; }

---

If you are requesting such features (or others)
It's best to start a new thread for each topic.

regards,
 - assaf
