Hi, i have to rename hunderts of files: 792041_100029699.mi 792090_100029501.mi . . . to 792041.mi 792090.mi . . . i tried: rename ??????_*.mi ??????.mi *.mi rename: ??????_.mi: kein Zugriff: Datei oder Verzeichnis nicht gefunden as you see, no sucess. (first file is gone, all others stay as they are) is there a easy way to do this (without writing a script)? simoN -- www.becherer.de ----------------------------------------------- - Das ist die vorlaeufig endgueltige Version! - Herbert C.
