Question

Can’t write shell, please help me,
I can only execute a few git commands

cd /home/xx
git add .
git commit -m '时间，如2016-03-03 12:0:03'
git push origin master

Resolved

cd /hmoe/xx
backtime=`date +%Y%m%d%H%M%S`
git add .
git commit -m bk_${backtime}
git push origin master

Answer 1

You also need to create a remote library,
git remote add origin "xx"
The double quotes are the .git file of the remote git, such as
https://github.com/yourname/yourproject.git

Answer 2

I wrote a similar script in php.
