git --- How to schedule `git push` on linux?

Question

I think the title describes my problem well: I want to schedule git push. To be more specific, I'd like to know how I can either

• tell git to make push at a specified time
• tell OS to execute git push at a specified time without re-authentication (preferably, in such a way that the other attempts to push shall require authentication.).

I'm on linux (Ubuntu 13.04) and thus scripting with bash will be fine.

Answer 1

There is nothing in git which includes:

• scheduling (this is provided by Ubuntu with cron jobs)
• authentication: it depends on the kind of listener (https, ssh, git, ...) you have on the remote side.

Depending on your remote url, you can, for instance:

• use a dedicate public/private ssh key.
• use encrypted credentials (username/password) with https url (as in "Configure Git clients, like GitHub for Windows, to not ask for authentication")

Answer 2

you can schedule such jobs using cron.

00 07 * * * git push

will run git push command everyday at 7 AM.
