E212: Cannot open Linux in write mode

Tell us what happened.

Background: There are multiple users under Linux who have their own passwords and root users.

Subject: I use zhengdengping user login want to go to copy Point user Lixianchu directory of Things

1. First found that there is no access to the Lixianchu user directory.

2. I use the temporary prompt permission method sudo cp-r others directory own directory (success small Happy under)

3. Because I copied the C program AH so I make results found error cannot create XXX. O

4. I want to ask what can not create it is puzzling so I use make directory VI a file results found in the Save

Hint: E212: cannot be opened in write mode

WORKAROUND: I put down the directory under the Lixianchu user and make it in the directory to the zhengdengping user.

VI is not an error.

Personal understanding: Because at the time of the CP is rooted, so he copied the past is also the root user created with root permissions, and users who log in to the user does not have root privileges, so will be an error personal understanding if someone knows the real reason or have a personal view back to let me know Thank you, Doug.
