$ man tar
don't change access times on dumped files
I suspect it means don't change the access time on the files that are being
dumped - every time a file is accessed its atime gets updated with the
current time (for tracking which files have been recently accessed; however,
if you're backing up the [entire] system it makes sense that you may not
want this time updated - every file would end up with a last access time
Quote:> and what is this
print directory names while reading the archive
A lesser version of -v, ie just display the directories in an archive as
opposed to the complete list of files? (Try it an see with:
$ tar --checkpoint -tf somearchive.tar
don't extract file modified time
When restoring, leave mod time as now as opposed to time originally on file?
(If all files restored with current time, make's, etc could break).
show record number within archive with each message
I presume that the first file is record 1, the second record 2, etc.
attempt to verify the archive after writing it
I presume this is in the good ol' days of tape backups to ensure the data
got written correctly to the file; and after writing it, it rewinds the
destination file and attempts to re-read it and see if it is correct.
