svn命令通常都有帮助，如果不知道命令怎么用，可以很方便获取帮助信息。比如有一个命令svn，但是不知道它有哪些子命令，可通过如下方式查询：
$ svn help知道了子命令，但是不知道子命令的用法，还可以查询：
$ svn help add另外，可能需要设置svn commit的message编辑器，这可以通过定义环境变量SVN_EDITOR或者VISUAL或者EDITOR处理，比如：
$ export SVN_EDITOR=/bin/vi本文以https来存取版本库，其他方式(比如file:///, svn://, https://, svn+ssh://等)操作基本是一样的。
开发人员常用命令
(1) 导入项目
$ cd ~/project $ mkdir -p svntest/{trunk,branches,tags} $ svn import svntest https://localhost/test/svntest --message "Start project" ... $ rm -rf svntest我们新建一个项目svntest，在该项目下新建三个子目录：trunk，开发主干；branches，开发分支；tags，开发阶段性标签。然后导入到版本库test下，然后把svntest拿掉。
(2) 导出项目
$ svn checkout https://localhost/test/svntest/trunk修订版本号的指定方式是每个开发人员必须了解的，以下是几个参考例子，说明可参考svn推荐书。
$ svn diff --revision PREV:COMMITTED foo.c # shows the last change committed to foo.c $ svn log --revision HEAD # shows log message for the latest repository commit $ svn diff --revision HEAD # compares your working file (with local changes) to the latest version # in the repository $ svn diff --revision BASE:HEAD foo.c # compares your “pristine” foo.c (no local changes) with the # latest version in the repository $ svn log --revision BASE:HEAD # shows all commit logs since you last updated $ svn update --revision PREV foo.c # rewinds the last change on foo.c # (foo.c's working revision is decreased) $ svn checkout --revision 3 # specified with revision number $ svn checkout --revision {2002-02-17} $ svn checkout --revision {15:30} $ svn checkout --revision {15:30:00.200000} $ svn checkout --revision {"2002-02-17 15:30"} $ svn checkout --revision {"2002-02-17 15:30 +0230"} $ svn checkout --revision {2002-02-17T15:30} $ svn checkout --revision {2002-02-17T15:30Z} $ svn checkout --revision {2002-02-17T15:30-04:00} $ svn checkout --revision {20020217T1530} $ svn checkout --revision {20020217T1530Z} $ svn checkout --revision {20020217T1530-0500}(3) 日常指令
$ svn update $ svn add foo.file $ svn add foo1.dir $ svn add foo2.dir --non-recursive $ svn delete README $ svn copy foo bar $ svn move foo1 bar1 $ svn status $ svn status --verbose $ svn status --verbose --show-updates $ svn status stuff/fox.c $ svn diff $ svn diff > patchfil $ svn revert README $ svn revert修改冲突发生时，会生成三个文件：.mine, .rOLDREV, .rNEWREV。比如：
$ ls -l sandwich.txt sandwich.txt.mine sandwich.txt.r1 sandwich.txt.r2解决修改冲突方式之一：修改冲突的文件sandwich.txt，然后运行命令：
$ svn resolved sandwich.txt方式之二：用库里的新版本覆盖你的修改：
$ cp sandwich.txt.r2 sandwich.txt $ svn resolved sandwich.txt方式之三：撤销你的修改，这种方式不需要运行resolved子命令:
$ svn revert sandwich.txt Reverted 'sandwich.txt' $ ls sandwich.* sandwich.txt确保没问题后，就可以提交了。
$ svn commit --message "Correct some fatal problems" $ svn commit --file logmsg $ svn commit(4) 检验版本历史
$ svn log $ svn log --revision 5:19 $ svn log foo.c $ svn log -r 8 -v $ svn diff $ svn diff --revision 3 rules.txt $ svn diff --revision 2:3 rules.txt $ svn diff --revision 4:5 https://svn.red-bean.com/repos/example/trunk/text/rules.txt $ svn cat --revision 2 rules.txt $ svn cat --revision 2 rules.txt > rules.txt.v2 $ svn list https://svn.collab.net/repos/svn $ svn list --verbose https://svn.collab.net/repos/svn $ svn checkout --revision 1729 # Checks out a new working copy at r1729 … $ svn update --revision 1729 # Updates an existing working copy to r1729 …(5) 其他有用的命令
svn cleanup为失败的事务清场。
(6) 分支和合并
建立分支方法一：先checkout然后做拷贝，最后提交拷贝。
$ svn checkout https://svn.example.com/repos/calc bigwc A bigwc/trunk/ A bigwc/trunk/Makefile A bigwc/trunk/integer.c A bigwc/trunk/button.c A bigwc/branches/ Checked out revision 340. $ cd bigwc $ svn copy trunk branches/my-calc-branch $ svn status A + branches/my-calc-branch $ svn commit -m "Creating a private branch of /calc/trunk." Adding branches/my-calc-branch Committed revision 341.建立分支方法二：直接远程拷贝。
$ svn copy https://svn.example.com/repos/calc/trunk \ https://svn.example.com/repos/calc/branches/my-calc-branch \ -m "Creating a private branch of /calc/trunk." Committed revision 341.建立分支后，你可以把分支checkout并继续你的开发。
$ svn checkout https://svn.example.com/repos/calc/branches/my-calc-branch假设你已经checkout了主干，现在想切换到某个分支开发，可做如下的操作：
$ cd calc $ svn info | grep URL URL: https://svn.example.com/repos/calc/trunk $ svn switch https://svn.example.com/repos/calc/branches/my-calc-branch U integer.c U button.c U Makefile Updated to revision 341. $ svn info | grep URL URL: https://svn.example.com/repos/calc/branches/my-calc-branch合并文件的命令参考：
$ svn diff -r 343:344 https://svn.example.com/repos/calc/trunk $ svn merge -r 343:344 https://svn.example.com/repos/calc/trunk $ svn commit -m "integer.c: ported r344 (spelling fixes) from trunk." $ svn merge -r 343:344 https://svn.example.com/repos/calc/trunk my-calc-branch $ svn merge https://svn.example.com/repos/branch1@150 \ https://svn.example.com/repos/branch2@212 \ my-working-copy $ svn merge -r 100:200 https://svn.example.com/repos/trunk my-working-copy $ svn merge -r 100:200 https://svn.example.com/repos/trunk $ svn merge --dry-run -r 343:344 https://svn.example.com/repos/calc/trunk最后一条命令仅仅做合并测试，并不执行合并操作。
建立标签和建立分支没什么区别，不过是拷贝到不同的目录而已。
$ svn copy https://svn.example.com/repos/calc/trunk \ https://svn.example.com/repos/calc/tags/release-1.0 \ -m "Tagging the 1.0 release of the 'calc' project." $ ls my-working-copy/ $ svn copy my-working-copy https://svn.example.com/repos/calc/tags/mytag Committed revision 352.后一种方式直接把本地的工作拷贝复制为标签。
此外，你还可以删除某个分支。
$ svn delete https://svn.example.com/repos/calc/branches/my-calc-branch \ -m "Removing obsolete branch of calc project."管理人员常用命令
(7) 版本库管理
$ svnadmin help ... $ svnadmin help create ... $ svnadmin create --fs-type bdb /usr/local/repository/svn/test $ chown -R svn.svn /usr/local/repository/svn/test建立版本库，库类型为bdb（使用Berkeley DB做仓库），库名称为test。
svn版本库有两种存储方式：基于Berkeley DB(bdb)或者基于文件系统(fsfs)，通过 --fs-type可指定存储方式。
(8) 查询版本库信息
$ svnlook help ... $ svnlook help tree ... $ svnlook tree /usr/local/repository/svn/test --show-ids ...
