以下这篇博文不错,这个问题会经常遇到,特地转过来分享给初学的朋友:
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
Found a swap file by the name ".Test.java.swp"
owned by: root dated: Wed Dec 7 13:52:56 2011
file name: /var/tmp/Test.java
modified: YES
user name: root host name: localhost
process ID: 26153 (still running)
While opening file "Test.java"
dated: Wed Dec 7 14:00:46 2011
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
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.swp
rm: remove regular file `.Test.java.swp'? y
[root@localhost tmp]#
