Hi

My thoughts regarding which properties / fields can be useful to have in 
history (originally pertaining to another shell but hope it's helpful):

Maybe what I
really want is something like $?, but instead of containing exit
status, it would contain information from a struct rusage (derived
from wait4) for the last command. Or something like that anyway.

I would like having those variables, too. There was a related discussion
some time ago, and a workaround was mentioned (using PROMPT_COMMAND and
traps if I remember correctly), but I didn't like that approach too
much.

Would having such variables solve your needs? (using PROMPT_COMMAND to
copy them into a file, perhaps). I would expect that storing the values
from last wait4 would be much less intrusive than messing with history.


Kind regards
