Tom 决定为他们的项目添加README文件。因此，他创造了README文件，并添加到该TODO列表。在加入这个文件库在修订版本6。

[tom@CentOS trunk]$ cat README 
/* TODO: Add contents in README file */

[tom@CentOS trunk]$ svn status
?       README

[tom@CentOS trunk]$ svn add README 
A         README

[tom@CentOS trunk]$ svn commit -m "Added README file. Will update it's content in future."
Adding         trunk/README
Transmitting file data .
Committed revision 6. 

Jerry 检出最新的代码，这是修订版本6。他就立刻开始工作。经过几个小时的Tom更新README文件并提交了他的变化。修改README这个样子。

[tom@CentOS trunk]$ cat README 
* Supported operations:

1) Accept input
2) Display array elements

[tom@CentOS trunk]$ svn status
M       README

[tom@CentOS trunk]$ svn commit -m "Added supported operation in README"
Sending        trunk/README
Transmitting file data .
Committed revision 7.

现在，库是修订版本7 Jerry的工作拷贝是过时了。Jerry 还更新README文件，并尝试提交他的变化。

Jerry' 的README文件看起来像这样。

[jerry@CentOS trunk]$ cat README 
* File list

1) array.c	Implementation of array operation.
2) README	Instructions for user.

[jerry@CentOS trunk]$ svn status
M       README

[jerry@CentOS trunk]$ svn commit -m "Updated README"
Sending        trunk/README
svn: Commit failed (details follow):
svn: File or directory 'README' is out of date; try updating
svn: resource out of date; try updating

Step 1: 查看冲突

这是好事。Subversion的检测README文件已经改变，因为最后一次更新。因此，Jerry 更新自己的工作副本。

[jerry@CentOS trunk]$ svn up
Conflict discovered in 'README'.
Select: (p) postpone, (df) diff-full, (e) edit,
        (mc) mine-conflict, (tc) theirs-conflict,
        (s) show all options:

Subversion抱怨README文件有冲突，Subversion不知道如何解决这个问题。所以Jerry 选择 df 查看冲突。

[jerry@CentOS trunk]$ svn up
Conflict discovered in 'README'.
Select: (p) postpone, (df) diff-full, (e) edit,
        (mc) mine-conflict, (tc) theirs-conflict,
        (s) show all options: df

Step 2: 延缓冲突

Jerry 选择推迟（p）选项，这样他就可以解决冲突。

Select: (p) postpone, (df) diff-full, (e) edit, (r) resolved,
        (mc) mine-conflict, (tc) theirs-conflict,
        (s) show all options: p
C    README
Updated to revision 7.
Summary of conflicts:
  Text conflicts: 1

在文本编辑器中打开README文件后，他意识到，Subversion会包含Tom 的代码和他冲突标记代码。

[jerry@CentOS trunk]$ cat README
<<<<<<< .min
* File list

1) array.c	Implementation of array operation.
2) README	Instructions for user.
=======
* Supported operations:

1) Accept input
2) Display array elements
>>>>>>> .r7

Jerry 希望 Tom 同他的变化一起修改，所以他只是删除了行包含冲突标记。

所以修改后的README文件会如下这个样子。

[jerry@CentOS trunk]$ cat README
* File list

1) array.c	Implementation of array operation.
2) README	Instructions for user.

* Supported operations:

1) Accept input
2) Display array elements

Jerry 解决冲突并提交，并让他重试。

[jerry@CentOS trunk]$ svn commit -m "Updated README"
svn: Commit failed (details follow):
svn: Aborting commit: '/home/jerry/project_repo/trunk/README' remains in conflict
 
[jerry@CentOS trunk]$ svn status
?       README.r6
?       README.r7
?       README.mine
C       README

Step 3: 解决冲突

这里是C字母表示有README文件冲突。Jerry 解决冲突，但没有告诉Subversion他解决冲突。他使用解决命令通知Subversion有关解决冲突

[jerry@CentOS trunk]$ svn resolve --accept=working README
Resolved conflicted state of 'README'

[jerry@CentOS trunk]$ svn status
M       README

[jerry@CentOS trunk]$ svn commit -m "Updated README"
Sending        trunk/README
Transmitting file data .
Committed revision 8.
