dbmail-sievecmd BUG

If you make a mistake and forget to give the name of the
script:

dbmail-sievecmd  -u <username> -i <filename>

then the command silently hangs forever. Could it possibly
instead 
return an error please?

Hi Michael,

I believe if you omit the <filename> then it expects
the script to come 
from stdin. There are a lot of other utilities like this
also (e.g. grep)

The way to test is to press CTRL-D - if it exits then it was
expecting 
data from stdin.

Regards,
Josh.

You're right. I wasn't thinking about it as I forgot the
script name, 
but entered the filename, which is translated as scriptname
then. That 
made it confusing.

Right, the syntax is like this:

dbmail-sievecmd -u <username> -i [scriptname
[filename]]

I could write a line to stderr like "Please enter data
for <scriptname>
on stdin" which would clue you in to what's happening
and give
confirmation of the file name, in case it turns out to be
something
unexpected.

Yes, that could help resolve the confusion. I guess others
will run into 
the same sometimes, so it's better to write that info. Maybe
only write 
that info if the script was called from command line, not
from within 
another script? I don't know how to do that, though.
Possibly only 
write that message if stdin has no input available?
