一、创建密钥
ssh-keygen -t rsa -C 'xxx@xxx.com' -b 4096
chown -R xxx:xxx /code
二、安装问题
若安装git的时候遇到如下问题：
The following packages have unmet dependencies:
git : Depends: liberror-perl but it is not installable
E: Unable to correct problems, you have held broken packages.
需要先执行：
sudo apt-get update
sudo apt-get upgrade
再安装：
sudo apt install git
三、回退版本
git log

rm all .gitignore
git reset 7742b9158fd5558fbd88767f25834643f86f6916 --hard
四、其它
# 替换ignore的名字
find ./ -name .gitignore |xargs -i echo mv \"{}\" \"{}\" | sed 's/gitignore/_gitignore_bak/2g' | sh
