linux下vi操作Found a swap file by the name

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：

?

E325: ATTENTION

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.swp

rm: remove regular file `.Test.java.swp'? y

[root@localhost tmp]#?
