    + 不像git有暂存区，svn在提交时只能将需要提交的文件列在命令里: `svn commit -m 'commit message' file1.c file2.c`
    + 撤销当前的所有更改: `svn revert -R .`
    + merge需要先得到revision的范围: `svn log /branches/feature_233 --stop-on-copy; svn merge /branches/feature_233 -r 999:1000`

    svn: E160013: '/svn/shire/!svn/bc/135926/branches/miaomia/meow' path not found
    ```

    先检查下哪里拼错了。

    ```
    svn: Failed to add directory 'waymeet': an unversioned directory of the same name already exists
    ```

    `svn switch`时如有遇到如此提示，删掉这个`waymeet`文件重新执行原先的`svn switch`。

    ```
    svn st -q 时列出来一坨S状态的文件
    ```

    如果`svn switch`被中断会出现这种情况。

    恢复: `svn info bad_file` 查看某个S状态的文件所在的分支，然后`svn switch`到这个分支。

    git svn branch foo
    git checkout -b foo -t remotes/foo
    git commit

    ```

    + Q: Could not unmemoize function `lookup_svn_merge', because it was not memoized to begin with at /usr/local/Cellar/git/1.7.6/libexec/git-core/git-svn line 3226

    A： `rm -rf .git/svn/.caches`

    + Q: Multiple branch paths defined for Subversion repository. You must specify where you want to create the branch with the --destination argument.

    A: 修改.git/config，添加: `branches = branches/liyazhou/*:refs/remotes/*`到`[svn-remote "svn"]`下。

    ### crontab

    crontab并没有直接向用户暴露配置文件的位置，是因为crontab这种比较敏感的脚本，是不能容忍语法错误的。`crontab -e`保存之后，就相当于经过了一层语法检验。编辑crontab：

    crontab -e
