原理

其原理如下： 

1，取得svn的兩個版本之間的diff資料

target=https://svn.xxx.com/erp/trunk/cms/cmsnew

   start_version=113121

   end_version=113128

   步驟一，使用svn diff命令取得SVN兩個版本diff檔案

   svn diff -r$start_version:$end_version$target --username lizejun --password xxx >svndiff.log

   步驟二，然後將檔案取得 開頭為+的行，處理後去掉空行，計算行數

   grep "^+" svndiff.log | grep -v"^+++" | sed 's/^.//'| sed s/[[:space:]]//g |sed '/^$/d'|wc -l

2，取得某個RD在兩次上線版本之間增加的程式碼行數

  步驟一，使用svn log命令取得$rdname提交程式碼的svn版本號

  svn log -q $target -r$start_version:HEAD --username lizejun --password xxx |awk '{print $1,$3}'|grep$rdname |awk '{print \$1}'

 步驟二，將取得的版本號與上一個版本做操作1中的工作，統計程式碼的增加情況

   for rev in ${revs};do

       rev=${rev:1}

       last_rev=$((rev-1))

       ${SVN_CMD} diff -r${last_rev}:${rev} $target --username $USERNAME --password$PASSWD  > $TEMPFILE

       count=`grep "^+" $TEMPFILE | grep -v "^+++" |sed 's/^.//'| sed s/[[:space:]]//g |sed '/^$/d'|wc -l`

       TOTAL=$((TOTAL+count))

       rm -rf $TEMPFILE

    done    

程式碼指令碼

//向我們公司偉大的作者致敬，為防止挖牆腳，去掉作者

#! /bin/bash
# 計算有效變更程式碼量的指令碼
# 包括註釋，但不包括新增的空行
version() {
    OS=`uname -o`
    echo "svn_counter ($OS) 0.0.1"
}
