git clone silent不起作用

Question

I am trying to clone a repo automatically from a .bat file.

I use ssh so the .bat file first moves a " id_rsa " file to the " user\\.ssh " folder.

Then, when I run " git clone ssh://repo c:\\repo ", I get the question

The authenticity of host can't be established. 
RSA key fingerprint is ........ 
Are you sure you want to continue connecting (yes/no)?

If I answer yes manually it works and the " known_hosts " file is created in " user\\.ssh " folder. Now if I run the .bat file the git clone will work without the question.

I need to do this silently from the .bat file.
I have tried to answer yes from the .bat file and to add " > /dev/nul 2>&1 " but with no success.

Any ideas?

Answer 1

You should try and adapt " Can I automatically add a new host to known_hosts? " in order to add the remote server to your %USERPROFILE%\\.ssh\\known_hosts .

Even from your Windows bat script, you can use a /path/to/git/bin/bash -c '...' command.

c:\path\to\git\bin\bash -c 'ssh-keyscan -t rsa,dsa HOST 2>&1 | sort -u - ~/.ssh/known_hosts > ~/.ssh/tmp_hosts && mv ~/.ssh/tmp_hosts ~/.ssh/known_hosts'

That allows you to use linux commands like grep, sort, ... which are part of the git distribution.

Answer 2

Are you using an updated bash?. Essentially what you're doing here is redirect to /dev/null, which is "nowhere". If you want to do it silently you can try git clone git@gitlab.com:username/repo directory -q

Answer 3

为了使它工作，至少现在，我从另一台服务器下载known_hosts文件和id_rsa。
