关于swp文件：使用vi，经常可以看到swp这个文件,那这个文件是怎么产生的呢，当你打开一个文件，vi就会生成这么一个.(filename)swp文件以备不测，如果你正常退出，那么这个.(filename)swp文件将会自动删除。
比如：强行关闭vi或vim时，，电源突然断掉，或者你使用了Ctrl-zz。（正常的退出方式应该是Shift-ZZ）
这时候就会出现下面的情况了
<span style="font-family:SimSun;color:#ffffff;background-color: rgb(0, 0, 0);">E325: ATTENTIONFound a swap file by the name ".ceshi.c.swp"owned by: root dated: Sat Jul 4 19:51:46 2015file name: /c/ceshi.cmodified: YESuser name: root host name: c66-WRprocess ID: 2801While opening file "ceshi.c"dated: Sun Jul 5 12:38:54 2015NEWER than swap file!(1) Another program may be editing the same file.If this is the case, be careful not to end up with twodifferent 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 ceshi.c"to recover the changes (see ":help recovery").If you did this already, delete the swap file ".ceshi.c.swp"to avoid this message.Swap file ".ceshi.c.swp" already exists![O]pen Read-Only, (E)dit anyway, (R)ecover, (Q)uit:</span>
重点：解决办法
用下面的命令删除swp文件
rm .{your file name}.swp
例如：我的文件名是ceshi.c 那么就用这样的命令：rm .ceshi.c.swp (当然你前面也可以加-rf强制删除)
问： (vi 一个文件时怎么样可以不让它产生.swp文件？或不让他提示【“Swap file ".文件名.swp" already exists![O]pen Read-Only, (E)dit anyway, (R)ecover, (Q)uit:】)处理方法： 打开 vi /etc/vimrc 并在末尾添加 set noswapfile 后保存退出 OK
每个人在他的人生发轫之初，总有一段时光，
