I just got a new server for my website, and I'm trying to create a trunk in a folder where i can pull data from github.
That way I can easily get the latest version of the website, and copy the needed files to my www.

Git works fine, but then each time I do a:

git pull origin master

It asks me for a password! I want to be able to update git via a script, or even via PHP later on. So that I can update my server automatically. I've spend a few hours trying to figure out how to save the password but I couldn't, this is why I need your help.

I have followed a few instructions here:
http://help.github.com/ssh-key-passphrases/
But it didn't work.

I am SSHing from Windows to my machine using Putty. The server is a CentOS.

Now that I have added the script in ~/.bashrc as the tutorial told me to do, each time I connect with Putty I have a new line saying: 

Could not open a connection to your authentication agent.

one thing i did find, if I write this in Putty: exec ssh-agent bash it asks me for the password, and doesn't ask until I restart Putty. The problem is when I restart it forgets it, and also if I would like to run this with another program (PHP) it wouldn't work. – xtrimsky Dec 2 '11 at 4:40
is this a private github repository or public? – lunixbochs Dec 2 '11 at 7:47

Try using expect. You can automatically supply the password to git through an automation script.

Just make sure your script has tight permissions -having plaintext passwords in scripts is usually Bad Idea™.

Edit:

Since I can't write code properly in the comment section below, you could write something like this:

#!/usr/bin/env expect
set password "<your-password>"
spawn /usr/bin/git pull
expect "<exact passphrase>"
send "$password\r"

expect was something i tried using too but It didn't work. This is how I did it: yum install expect (on centos) (it installed stuff and worked) And then in my batch script after git pull I entered expect "Enter passphrase...: (don't remember the exact phrase), and then entered: send: "mypassword". Am I doing something wrong ? – xtrimsky Dec 2 '11 at 17:13
Check again the edited the answer. – dkaragasidis Dec 2 '11 at 18:50
Ok so I've modified my file update.sh to look like this: #!/usr/bin/env expect set password "wei534kfer3" spawn /usr/local/bin/git pull origin master expect "Enter passphrase for key '/root/.ssh/id_rsa':" send "$password\r" I then executed: expect update.sh It shows something like that in my bash: ` spawn /usr/local/bin/git pull origin master Enter passphrase for key '/root/.ssh/id_rsa': [root@u15927644 trunk]#` (in almost a single line), and does not execute the pull request :(. No error. – xtrimsky Dec 3 '11 at 2:56
