rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1518)

According to the experience of others, rsync error: some files/attrs were not transferred and http://www.lingzhong.cn/tech/23765.htm
Method 1 is to modify the configuration file, and method 2 is to change the permissions.
The first one was a bit of a hassle, the second one was too much.
At this point, run the sync again,

linlf@ccrfox247:~/project/man$ ./transfer-cuda90.sh

List that file cannot be synchronized. The original owner and group of this file are root, but I synchronized the past user is a normal user, not root, so I reported an error.

ls -lh /home/linlf/project/nohup.out
-rw------- 1 root root 207K 6月  14 17:27 /home/linlf/project/nohup.out

It’s also easy to change the file permissions to my own:

sudo chown linlf /home/linlf/project/nohup.out
sudo chgrp linlf /home/linlf/project/nohup.out

Finally, modify the permissions of the folders to be synchronized altogether:

sudo chown -R linlf /home/linlf/project
sudo chgrp -R linlf /home/linlf/project

Re-run the script:

rsync -avz /home/linlf/project [email protected]:/home/linlf

Done
