当我在linux下用vi打开Test.java文件时php
[root@localhost tmp]# vi Test.javajava
会出现以下信息:linux
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
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vim
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。session
注:以.开头的文件就是隐藏文件ui
当我把该隐藏文件删除后再次打开就没有上面的警告了。this
[root@localhost tmp]# rm .Test.java.swpblog
rm: remove regular file `.Test.java.swp'? yrem
[root@localhost tmp]#it
