vi/vim文件加密和乱码的处理

在使用vi或者vim编辑文件是,在存盘退出的时候,应该使用:wq或者:x退出,但是有时候可能不小心按了:X,
这时体统会提示:
Enter encryption key:

如果你没有仔细看提示,比如继续输入:x,
Enter encryption key: *
Enter same key again: *
那么实际上就给这个文件加密了,下次打开就会要求你输入密键,例如:
[oracle@ts01 admin]$ vim $ORACLE_HOME/sqlplus/admin/glogin.sql

Enter encryption key: *

define gname=idle
column global_name new_value gname
select lower(user) || ‘@‘ || substr( global_name,1,
decode( dot, 0, length(global_name), dot-1) ) global_name
from (select global_name, instr(global_name,’.’) dot from global_name );
set sqlprompt ‘&gname> ‘
set termout on
[oracle@ts01 admin]$
否则就显示乱码。
要接触密码,步骤如下:
vim file
Enter encryption key: 输入密码
:set key=
:w!
例如:
[oracle@ts01 admin]$ vim $ORACLE_HOME/sqlplus/admin/glogin.sql
Enter encryption key: *     输入密码
。。。。。。。。文件正文原文
:set key=
:w!  存盘
现在这个密码的口令限制就解除了。

测试用:x存档文件好像无法解除密码
