Does Linux do something similar to your > knoweledge? /dev/st0 rewinds when you close the device (ie: at the end of a command like "find . -print | cpio -oa | dd of=/dev/st0". However, if you're writing a script and want more than one file per tape, a command like "/bin/mt -f /dev/st0 fsf 1" won't do what you initially might think. /dev/nst0 does not rewind. Thus: "/bin/mt -f /dev/nst0 rewind" is required after use. hope this help'idly, -S ============================================================================ /| | Quote of the day: | \'o.O' | "Linux-- because rebooting is | Steve Siegfried =(___)= | for adding hardware" | sos at zjod.net U | - Billy Wheeler | ============================================================================ --------------------------------------------------------------------- To unsubscribe, e-mail: tclug-list-unsubscribe at mn-linux.org For additional commands, e-mail: tclug-list-help at mn-linux.org
