SVN : how to create a branch from certain revision of trunk

Question

以下操作只会从主干的头部修订版创建分支。如何从特定修订版创建分支？谢谢。

$ svn copy http://svn.example.com/repos/calc/trunk \
       http://svn.example.com/repos/calc/branches/my-calc-branch \
  -m "Creating a private branch of /calc/trunk."

查看帮助命令:

svn help copy

  -r [--revision] arg      : ARG (some commands also take ARG1:ARG2 range)
                             A revision argument can be one of:
                                NUMBER       revision number
                                '{' DATE '}' revision at start of the date
                                'HEAD'       latest in repository
                                'BASE'       base rev of item's working copy
                                'COMMITTED'  last commit at or before BASE
                                'PREV'       revision just before COMMITTED

要使用您的示例在命令行上实际指定它:

svn copy -r123 http://svn.example.com/repos/calc/trunk \
    http://svn.example.com/repos/calc/branches/my-calc-branch

其中 123 是您要复制的主干中的修订号。正如其他人所指出的，您还可以使用 @ 语法。就我个人而言，我更喜欢将修订号 # 与 URL 更清晰地分开。

正如帮助中所述，您也可以用某些单词替换修订号:

svn copy -rPREV http://svn.example.com/repos/calc/trunk \
    http://svn.example.com/repos/calc/branches/my-calc-branch

将复制“提交之前的修订”。
