"rpmdrake > /dev/null" vypisuje output??

Chapu to snad spatne? Mel jsem zato, ze kdyz vystup necham zapisovat do /dev/null, tak se nebude na obrazovce objevovat? Takhle mi zmineny prikaz vypisuje

pro upresneni poustim to ve WM, v gnome-terminalu.

k cemu potrebujes, aby se presmeroval vystup rpmdraku do /dev/null ???

rekl bych, ze je to zalezitost jenom *drake a podobnych, protoze to tak dela treba i drakconnect, ale treba tuxcmd --debug >/dev/null nevypisuje nic
stejne tak, kdyz vyzkousis nejakej jinej prikaz, tak to funguje
napr. urpmf mc >/dev/null tak ti to na obrazovku nic nevypise :idea:

ono to vypisuje lebo ty si presmeroval iba stdout a toto vypisuje errout
ak xces presmerovat errout tak musis pridat este '2>/dev/null'
pripadne ak spolocne s stdout tak 'prikaz >/dev/null 2>&1' co znamena presmerovanie errout do stdout ktory uz je presmerovany do /dev/null
dufam ze chapes 8-)
