当我在linux下用vi打开Test.java文件时java
[root@localhost tmp]# vi Test.javalinux
会出现以下信息:vim
E325: ATTENTION ide

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.
"Test.java" 11L, 237C

缘由是我以前有一次使用vi 操做Test.java文件时出现了异常中断,因此在当前目录下产生了一个.Test.java.swp文件
可是我使用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.swp
rm: remove regular file `.Test.java.swp'? y
[root@localhost tmp]#
