Derrick,

  alright I will fallback to that if I have to copy large amounts of data, but 
usually I am using konqueror to copy files ... Is there anyway, but  a 
script, to mass renice process with some shared characteristics like the 
command? I mean something like killall, but of course it shouldn't kill but 
renice ;-)

Cheers,
Mariano
