SVN導出差別版本更新的文件列表

對於在服務器上沒有使用版本控制的運維人員來講,每次SVN修改的文件都須要查看更改日誌,一個個查找出來再更新到服務器,過程實在是痛苦 那麼有沒有一種方法跑個命令比對一下版本就嘩啦啦的把修改好的文件複製出來而且是相同的目錄結構呢,答案是有的bash

#!/bin/bash
 
if [ ! $1 ] || [ ! $2 ] || [ ! $3 ] || [ ! $4 ]; then
    echo "Please enter a revision from, revision to, SVN repository, and target directory"
    exit
fi
 
# set up nice names for the incoming parameters to make the script more readable
revision_from=$1
revision_to=$2
repository=$3
target_directory=$4
 
# the grep is needed so we only get added/modified files and not the deleted ones or anything else
# if it's a modified directory it's " M" so won't show with this command (good)
# if it's an added directory it's still "A" so will show with this command (not so good)

# echo "svn diff --summarize -r$revision_from:$revision_to $repository | grep "^[AM]'"
 
for line in `svn diff --summarize -r$revision_from:$revision_to $repository | grep "^[AM]"`
do
    # each line in the above command in the for loop is split into two:
    # 1) the status line (containing A, M, AM, D etc)
    # 2) the full repository and filename string
    # so only export the file when it's not the status line
    if [ $line != "A" ] && [ $line != "AM" ] && [ $line != "M" ]; then
        # use sed to remove the repository from the full repo and filename
        filename=`echo "$line" |sed "s|$repository||g"`
        # don't export if it's a directory we've already created
        if [ ! -d $target_directory$filename ]; then
            directory=`dirname $filename`
            mkdir -p $target_directory$directory
            svn export -r $revision_to $line $target_directory$filename
        fi
    fi
done
 
# to summarize any deleted files or directories at the end of the script uncomment the following line
#svn diff --summarize -r$revision_from:$revision_to $repository | grep "^[D]"

直接把上面代碼保存修更名稱爲svndiff,並加上可執行權限服務器

使用方法:運維

svndiff 前一個版本號  後一個版本號  項目路徑  導出的文件存放路徑
