Quoting Timothy J Luoma (luomat(_at_)peak(_dot_)org):
HOWEVER I'd like this to go into formail's man page... it would help folks
figure it out... cost me about 30 minutes (duh!)
It is in the formail man page:
formail [+skip] [-total] [-bczfrktnedqBY] [-p prefix]
[-D maxlen idcache]
[-x headerfield] [-X headerfield]
[-a headerfield] [-A headerfield]
[-i headerfield] [-I headerfield]
[-u headerfield] [-U headerfield]
[-R oldfield newfield]
[-m minfields] [-s [command [arg ...]]]
Note that it clearly shows that the "headerfield" must follow the
"-x". You _can_ compress things a bit more than the above form
shows, but that doesn't mean that you _should_. If you
had written the original as "formail -z -x headerfield" it would
have worked out all right, and it only would have cost three
extra characters (as opposed to "formail -zxheaderfield", which
is a more compressed form of the correct syntax). What is gained
by cutting corners?
