当我在linux下用vi打开Test.java文件时[root@localhost tmp]# vi Test.java会出现如下信息：

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 Test.java"

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

If you did this already, delete the swap file ".Test.java.swp"

to avoid this message.

Press ENTER or type command to continue

原因是我之前有一次使用vi 操作Test.java文件时出现了异常中断，所以在当前目录下产生了一个.Test.java.swp文件但是我使用ls命令查看该目录下，却发现没有这个文件，后来使用ls -a命令查看才知道Test.java.swp是一个隐藏文件。注：以.开头的文件就是隐藏文件当我把该隐藏文件删除后再次打开就没有上面的警告了。[root@localhost tmp]# rm .Test.java.swprm: remove regular file `.Test.java.swp'? y[root@localhost tmp]#
