Specifying databases on the command line

[John Rudd <jr...@ucsc.edu>]

is there any way to set the directory for the user's spamassassin 
directory from the command line for sa-learn?  I know that I can set 
the location of the user's preferences file (with -p), or the system 
wide config directory (with -C) ... but what I want is sort of a 
crossing of the two.

(users wont be directly accessing things, and I don't want to waste 
space on individual prefs files that specify the locations in their 
options; I'd rather just be able to set the location of the AWL and 
Bayes databases from the sa-learn command line)

Is there a way to do that?  Will that effectively happen if I give a 
directory, instead of a file, to the -p option?  If I do that, will it 
also build a user prefs file for them in the same directory (which I 
don't want)?

It might also be nice to have -O cli argument that lets you set config 
options on the command line (for both spamassassin and sa-learn), like:

sa-learn -O option1=value1 -O option2=value2 --file $MESSAGE

That would allow this type of thing to be done in a general way.

(btw: I'm still running 2.50, so if this has been solved by a more 
recent version, please just let me know which minimum version I need to 
upgrade to)
