E325: ATTENTION error resolution for Vim editor use: Make Vim edit file prompt E325: ATTENTION error resolution

Recently, I encountered a problem when using Vim editor. Due to the business needs of the company, I modified the configuration computer port and conducted routine terminal command line operation. As a result, I encountered an E325:ATTENTION error message, as shown below:

E325: ATTENTION

Found a swap file by the name “/etc/.hosts.swp”

If this is the case, use “:recover” or “vim -r /etc/hosts”

    to recover the changes (see “:help recovery”).

    If you did this already, delete the swap file “/etc/.hosts.swp”
