Fair enough, although counter-intuitive to me at least.
no, it's not counter-intuitive if you remember that the shell expands wildcards BEFORE passing the args to the program... so 'cd / ; tar clvf - *' gets expanded to 'cd / ; tar clvf - bin boot cdrom console dev etc floppy home lib lost+found mnt proc root sbin tmp usr var vmlinuz vmlinuz.old' and tar does exactly what you tell it to do - archive all of those files and directories. it will archive each of the directories in the order listed on the command line and for each one, the -l option will restrict it to just that fs mount. craig -- craig sanders -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
