如何正确地将 'git push' 命令添加到 crontab - Ubuntu
How to correctly add 'git push' command to crontab - Ubuntu
我认为这是一个简单的问题，但我添加了一个文件夹 Origin Master 就像 this guide oriented.
我创建了一个文件 backupgit.cron 并在其中添加了以下命令：
cd /var/bkpfolder/
git add .
git commit -m "another commit"
git push origin master
并且在 crontab -e 我加入了以下行：
30 * * * * /var/bkpfolder/backupgit.cron
问题是，我添加的用于测试此 crontab 的（新）文件从未上传过...如果我 运行 手动 backupgit.cron 处的命令它们确实有效。
我认为这与转到 origin master 文件夹（cd /var/bkpfolder/？）执行推送命令有关，所以我要找的是 对 backupgit.cron
中规定的 /bkpfolder/ 执行推送命令的正确方法
提前致谢！
您的来源 master 必须是 bare-repository 否则分支可能无法签出。
如果它不是 bare-repository 并且将被推送的分支被签出，您将收到以下错误：
git push origin master --force
Counting objects: 3, done.
Writing objects: 100% (3/3), 214 bytes | 0 bytes/s, done.
Total 3 (delta 0), reused 0 (delta 0)

To /Users/Roman/gittest/master
! [remote rejected] master -> master (branch is currently checked out)
error: failed to push some refs to '/Users/Roman/gittest/master'
解决方案
如果您不想使用 bare-repository，您必须签出 bkpfolder 和 master 目录不同的分支。
开箱即用示例
为了更好地理解，我将遥控器 master 重命名为 origin。
mkdir main_backup
cd main_backup && git init --bare && cd ..
git clone main_backup bkpfolder
cd bkpfolder && echo "This is a test" >> test.txt
git add .
git commit -m 'Automatic backup'
git push origin master
我弄清楚我做错了什么......正如我所说，当我在文件夹内时 backupgit.cron 内的命令起作用（读作不是默认文件夹 crontab 是）......所以我刚刚发现在 git 命令的开头我可以指定我的操作文件夹，如 git -C /var/bkpfolder/
所以我将 backupgit.cron 中的内容替换为：
cd /var/bkpfolder/
git add .
git commit -m "another commit"
git push origin master
收件人：
git -C /var/bkpfolder/ add .
git -C /var/bkpfolder/ commit -m "another commit"
git -C /var/bkpfolder/ push origin master
