Right. One can also do exec 3 < image.iso growisofs -Z /dev/cdrom1=/dev/fd/3 & growisofs -Z /dev/cdrom2=/dev/fd/3 & ... and whatever equivalent in C, i.e. open once, pass to many. It is *as good* as letting growisofs open it. Actually *better*, because it's not subject to race condition. You only have to make sure that the file is opened with O_LARGEFILE or with open64. Some script interpretators might fail to. A. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
