本人在测试svn hook的时候遇到了下面的错误，网上查资料认为是没有执行perl脚本的权限。
$ svn commit -m "commit msg"
Adding wcao\commit_msg.txtTransmitting file data .svn: E165001: Commit Failed (details follow):
svn: E165001: Commit blocked by pre-commit hook (exit code 2) with output:
Can't do setuid (cannot exec sperl)
===================================================
Error: SVN COMMIT TO LOCKED BRANCH REJECTED !
也许你在svn hook上也遇到过相同的问题，也许在别的地方遇到过此问题，解决方法都是一样的，给用户组添加可执行权限。
chmod a+x scriptName
