There's the general opinion, that executing code  with  system(3)
is  a bad idea. Instead, programs manually split the command line
into words and call exec(3) instead. Usually this splitting  into
words  is  too  primitive  and covers only the most general cases
(i.e. no quoting). Thus, people insert wrapper  scripts  if  they
want  to  do  fancier  stuff.  No, where's the advantage of using
exec(3) instead of system(3) then?


I could quickly solve a simple problem,  which  came  up  on  the
masqmail  list.   The  question was asked by Sebastian M. Alvarez
from Cordoba, Argentina.  Hey, I had been in Argentina,  about  a
year  ago.  I  asked  him in Spanish, how the weather would be in
Cordoba. It's a truly good experience to know foreign  languages.
My  Spanish  (better:  Castellano)  isn't  good, but good enough,
that's what that matters. Sadly, my French is so bad that I can't
even talk for half a minute.


My mmh work is on idle, currently.
