svn 代码统计脚本

公司用的版本管理是svn。有时候就好奇自己到底改了多少行代码才完成任务的。于是在网上一通百度，结果还真有人写了个神奇脚本能够统计出一个人一段时间修改过的代码行数。云里雾里看了一下脚本主要用到了 svn diff功能。

code

#! /bin/bash  
# 计算有效变更代码量的脚本  
# 包括注释，但不包括新增的空行  
version() {  
    OS=`uname -o`  
    echo "svn_counter ($OS) 0.0.1"  
}

    echo "                      [-e END_REVISION] [-u USER_NAME]"  
    echo "                      [-p PASSWD]"  
    echo "       svn_counter [-v|-h]"  
    echo   
    echo "        -t,                 目标SVN库地址"
