For what ever reason, I have a lot of content on my TVbackup drive which isn't on my TV drive.
I want to copy all the files across which are on TVbackup but are not currently on TV.
If there is a file with the same name but a different size or date, I want to copy this across too, perhaps with a (1) after it, or something similar so it doesnt overwrite the existing file.
The end result is that the TV drive will end up having all of the files which are on the TVbackup drive as well as its own files.
My starting point is this:
But how do I make it skip if the same file (size and date) already exists in the destination.
Has anyone seen this before?
if i ls a particular directory (an email Maildir) i get a long list of files, if i 'du -h' that same directory, i get messages like:
du: `./1053894791.17207_0.srweb,S=6199': No such file or directory
strange. so using tab will complete this filename too, giving... (3 Replies)
Hi,
I would like to perform bash which would check the file A.txt to be size 0 or not. If the size is 0, I would copy file B.txt to replace A.txt.
Please help.
Thanks.

Has anyone ever used rsync to copy files locally on one server? (in this case from one SAN volume to another).
I am familiar with using rsync to copy files between servers, but not locally, I would usually use cp or or tar or something.
Is rsync slower? Does it use additional overhead of the... (4 Replies)

Hi
This is my situation
I have files on the left which I want to copy to the right. Once the files are copied to the right, they are processed and then deleted. The next time rsync runs I dont want it to copy the same files again, it should only copy any new files to the right.

Hi,
We have two (2) servers named primary and standby. There is a directory named /db01/archive that we need to keep in-sync.
Files get transferred from primary and standby. Sometimes when we do a failover or when there is a network issue, some files fail to get transferred.
I want to use... (3 Replies)
I use this
rsync --progress -r -u /media/andy/MAXTOR_SDB1/Ubuntu_Mate_18.04/* /home/andy/Ubuntu_18.04_Programs/Is there a way to have it not copy files such as these?

CD(9) BSD Kernel Developer's Manual CD(9)NAME
cd -- CDROM driver for the CAM SCSI subsystem
DESCRIPTION
The cd device driver provides a read only interface for CDROM drives (SCSI type 5) and WORM drives (SCSI type 4) that support CDROM type com-
mands. Some drives do not behave as the driver expects. See the QUIRKS section for information on possible flags.
QUIRKS
Each CD-ROM device can have different interpretations of the SCSI spec. This can lead to drives requiring special handling in the driver.
The following is a list of quirks that the driver recognize.
CD_Q_NO_TOUCH This flag tell the driver not to probe the drive at attach time to see if there is a disk in the drive and find out what
size it is. This flag is currently unimplemented in the CAM cd driver.
CD_Q_BCD_TRACKS This flag is for broken drives that return the track numbers in packed BCD instead of straight decimal. If the drive seems
to skip tracks (tracks 10-15 are skipped) then you have a drive that is in need of this flag.
CD_Q_NO_CHANGER This flag tells the driver that the device in question is not a changer. This is only necessary for a CDROM device with
multiple luns that are not a part of a changer.
CD_Q_CHANGER This flag tells the driver that the given device is a multi-lun changer. In general, the driver will figure this out auto-
matically when it sees a LUN greater than 0. Setting this flag only has the effect of telling the driver to run the initial
read capacity command for LUN 0 of the changer through the changer scheduling code.
CD_Q_10_BYTE_ONLY
This flag tells the driver that the given device only accepts 10 byte MODE SENSE/MODE SELECT commands. In general these
types of quirks should not be added to the cd(4) driver. The reason is that the driver does several things to attempt to
determine whether the drive in question needs 10 byte commands. First, it issues a CAM Path Inquiry command to determine
whether the protocol that the drive speaks typically only allows 10 byte commands. (ATAPI and USB are two prominent exam-
ples of protocols where you generally only want to send 10 byte commands.) Then, if it gets an ILLEGAL REQUEST error back
from a 6 byte MODE SENSE or MODE SELECT command, it attempts to send the 10 byte version of the command instead. The only
reason you would need a quirk is if your drive uses a protocol (e.g., SCSI) that typically does not have a problem with 6
byte commands.
