我用vi 编辑文件过程中我强制关闭编辑窗口,于是出现了问题,如

# Create  swap file by the name ".mrtg.cfg.swp"
          owned by: root   dated: Sat May  6 12:28:55 2006
         file name: /var/www/html/mrtg/mrtg.cfg
          modified: YES
         user name: root   host name: ujstest
        process ID: 4766
While opening file "mrtg.cfg"
             dated: Sat May  6 15:20:32 2006
      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 mrtg.cfg"
    to recover the changes (see ":help recovery").
    If you did this already, delete the swap file ".mrtg.cfg.swp"
    to avoid this message.
"mrtg.cfg" 27L, 538C
Hit ENTER or type command to continue  
请问怎么样才能恢复文件?

有人在编辑这个文件吧
先确认，如果没人在编辑这个文件

rm -f .mrtg.cfg.swp
