查看help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:

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

123您要复制的主干中的修订号将在何处.正如其他人所说,您也可以使用@语法.我个人更喜欢将修订版#与URL更清晰地分开.

如帮助中所述,您也可以使用某些单词替换修订#:

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

会复制"COMMITTED之前的修订".

Answer 2

$ svn copy http://svn.example.com/repos/calc/trunk@192 \
   http://svn.example.com/repos/calc/branches/my-calc-branch \
   -m "Creating a private branch of /calc/trunk."

其中192是您指定的修订版

您可以从SVN Book中找到此信息,特别是有关svn copy的页面

Answer 3

使用"@"字符附加修订:

svn copy http://src@REV http://dev

或者,使用-r [--revision]命令行参数.
