當我在linux下用vi打開Test.java文件時php
[root@localhost tmp]# vi Test.javajava
會出現以下信息: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
緣由是我以前有一次使用vi 操做Test.java文件時出現了異常中斷,因此在當前目錄下產生了一個.Test.java.swp文件vim
可是我使用ls命令查看該目錄下,卻發現沒有這個文件,後來使用ls -a命令查看才知道Test.java.swp是一個隱藏文件。session
注:以.開頭的文件就是隱藏文件ui
當我把該隱藏文件刪除後再次打開就沒有上面的警告了。this
[root@localhost tmp]# rm .Test.java.swpblog
rm: remove regular file `.Test.java.swp'? yrem
[root@localhost tmp]#it
