vi 或vim打开文件报错-Press ENTER or type command to continue

当在centos系统中，打开一个文件出现类似下面错误

E325: ATTENTION

Found a swap file by the name "/etc/vsftpd/.vsftpd.conf.swp"

          owned by: root   dated: Mon May 20 03:40:14 2019

         file name: /etc/vsftpd/vsftpd.conf

          modified: YES

         user name: root   host name: vultr.guest

        process ID: 16184

While opening file "/etc/vsftpd/vsftpd.conf"

      NEWER than swap file!

 

(1) Another program may be editing the same file.  If this is the case,

    be careful not to end up with two different instances of the same

    file when making changes.  Quit, or continue with caution.

(2) An edit session for this file crashed.

    If this is the case, use ":recover" or "vim -r /etc/vsftpd/vsftpd.conf"

    to recover the changes (see ":help recovery").

    If you did this already, delete the swap file "/etc/vsftpd/.vsftpd.conf.swp"

    to avoid this message.

"/etc/vsftpd/vsftpd.conf" 148L, 5454C

Press ENTER or type command to continue

这是因为之前打开过一次文件，然后连接异常退出，产生了缓存文件.vsftpd.conf.swp，当再次打开，提示已经打开过文件之类的信息，只需要删除缓存文件即可rm -rf .vsftpd.conf.swp
