svn文件版本还原

1、还原本地开发环境文件到某个版本
查看文件修改记录：svn log file_name
该目录下文件还原到某一版本（存在该版本的）：svn up -r 版本号
还原指定文件到某一版本：svn up -r 版本号 文件名称
例如：
（1）zhanghuijun@campostdev:~/cpst/campost/mlres/forms/disp> svn log opn_dom_item_modify.mfrm
------------------------------------------------------------------------
r5431 | huaruoxu | 2013-12-07 16:40:16 +0100 (Sat, 07 Dec 2013) | 1 line




------------------------------------------------------------------------
r4413 | lihaiquan | 2013-06-05 05:47:24 +0100 (Wed, 05 Jun 2013) | 2 lines

zhanghuijun@campostdev:~/cpst/campost/mlres/forms/disp> 
zhanghuijun@campostdev:~/cpst/campost/mlres/forms/disp> svn log opn_dom_item_modify.mfrm

或者提前一个版本号即可：
svn update -r 5430 opn_dom_item_modify.mfrm


2、还原SVN库环境文件到某个版本：
（1）更新到最新：svn update
（2）查看文件修改记录：svn log file_name
（3）使用旧版本文件：svn merge -r 新修订版序号:旧修订版序号 file_name
（4）提交：svn commt file_name
例如：
（1）zhanghuijun@campostdev:~/cpst/campost/mlres/forms/disp> svn update
Updating '.':
U    opn_dom_item_modify.mfrm
Updated to revision 5434.
（2）zhanghuijun@campostdev:~/cpst/campost/mlres/forms/disp> svn log opn_dom_item_modify.mfrm
------------------------------------------------------------------------
r5431 | huaruoxu | 2013-12-07 16:40:16 +0100 (Sat, 07 Dec 2013) | 1 line
