過程:

1.git svn clone http://10.6.60.40/svn/XXXX/SourceCode --authors-file=/root/author.txt --branches=26prpins backup
2.多少個小倉庫cp多少份backup, sh /root/scripts/cp.sh

[root@node64_2 tmp]# cat /root/scripts/cp.sh 
#!/bin/bash
read -p "please enter clone service " clone_service
read -p "please enter service " service_dir
for i in $service_dir
do 
    cp -a $clone_service $i
done
 

腳本說明:
1.小倉庫cp到root目錄下
2.執行腳本前在gitlab創建好項目,獲取ssh/http倉庫地址
3.在root目錄執行此remove_git.sh及cp.sh

[root@node64_2 scripts]# cat remove_git.sh 
#!/bin/bash

if [ $# -eq 1 ];then
up_level_dir=$1

do
        exclude_dir=${service_dir}
        cd /root/$service_dir
        for i in `ls |grep -v "^${up_level_dir}$";ls ${up_level_dir}|grep -v "^${exclude_dir}$"|sed -r s‘#(.*)#‘${up_level_dir}‘/\1#‘`
        do
                git filter-branch --force --index-filter ‘git rm --cached -r --ignore-unmatch ‘$i‘‘ --prune-empty --tag-name-filter cat -- --all   > /dev/null 2>&1

        git branch -D master
    for branch in prod inttest dev uat
        do
                git checkout ${branch}
                ls|grep -v "^${up_level_dir}$"|xargs rm -r
                mv ${up_level_dir}/${exclude_dir}/* ./
                rm -rf $up_level_dir
                git commit -am "remove dir"
                git add .
                git commit -am "test commit"
        done

done
else
    echo "example: /bin/bash $0 up_level_dir"

• git remote add origin [email protected]:CoreProjectNew/business/frontend.git
• git push origin --froce --all

  清理和回收本地倉庫空間

• du -sh .git/ 查看.git目錄大小
• rm -rf .git/refs/original/
• git reflog expire --expire=now --all
• git gc --prune=now
• git gc --aggressive --prune=now
• 執行完後確認.git目錄文件是否變小
