Well, restore(8) is the utility intended for looking at and extracting files from dump files. I don't know if you can do all those things directly from a dump file using restore. You may have to restore a file to disk first and then act on that file for some of them. But some might work. I usually make a directory I call 'unroll' somewhere with lots of extra space, put stuff there and work on things from there and clean up afterwards. But, you are welcome to experiment. ////jerry > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org" _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
