However, until recently wget had broken large file support and was unsuitable for downloading DVD ISOs. I would certainly not use: curl -C - ftp://ftp.someone.net/somefile.iso > somefile.iso as this would *definitely* not have the desired effect. Before even starting the curl program, the shell will overwrite the existing somefile.iso and connect standard output to a new, empty file of that name. The --output option should be used instead of a shell redirect. Paul. -- Paul Howarth <paul@xxxxxxxxxxxx>
