How to make a script to perform git pull?
提问by cyber8200
It is a common practice to perform git pullon dev/staging/productionserver(s). I frequently do so myself; I perform git pull almost 100 times a day on my production server running linux.
git pull在开发/登台/生产服务器上执行是一种常见的做法。我自己也经常这样做；我每天在运行 linux 的生产服务器上执行 git pull 几乎 100 次。
I figure, it's time to make a scriptto improve that.
我想，是时候制作一个脚本来改进它了。
pull.shwill do these 3 commands
pull.sh将执行这 3 个命令
- git pull
- enter my-password (when prompt)
- service nginx reload
- 拉
- 输入我的密码（出现提示时）
- 服务 nginx 重新加载
I've tried create my pull.shhere
我试过在这里创建我的pull.sh
#!/bin/bash
function pull {
git pull
password
service nginx reload
}
pull ;
Result
结果
After running the script that I have, I still got prompt to input the password.
运行我拥有的脚本后，我仍然提示输入密码。
Any hints / helps / suggestions will be much appreciated !
任何提示/帮助/建议将不胜感激！

You can use expectscript to interact with git authentication:
您可以使用expect脚本与 git 身份验证交互：
#!/usr/bin/expect -f
spawn git pull
expect "ass"
send "your_password\r"
interact
It waits for "ass" text (that matches "Password", "password", "passphrase") and then it sends your password.
它等待“ass”文本（匹配“Password”、“password”、“passphrase”），然后发送您的密码。
That script can be called from another bash script that will restart your server:
可以从另一个将重新启动服务器的 bash 脚本调用该脚本：
# Call script directly since the shell knows that it should run it with
# expect tool because of the first script line "#!/usr/bin/expect -f"
./git-pull-helper-script.sh
# Without the first line "#!/usr/bin/expect -f" the file with commands
# may be sent explicitly to 'expect':
expect file-with-commands
# Restart server
service nginx reload

The way to handle a passphrase is to use an ssh agent: that way, you only need to type in your passphrase once.
处理密码的方法是使用 ssh 代理：这样，您只需输入密码一次。
I have this in my dev user's ~/.bash_profile
我的开发用户中有这个 ~/.bash_profile
# launch an ssh agent at login, so git commands don't need to prompt for password
# ref: http://stackoverflow.com/a/18915067/7552
SSH_ENV=$HOME/.ssh/env
if [[ -f ~/.ssh/id_rsa ]]; then
function start_agent {
# Initialising new SSH agent...
ssh-agent | sed 's/^echo/#&/' > "${SSH_ENV}"
chmod 600 "${SSH_ENV}"
source "${SSH_ENV}" > /dev/null
ssh-add
}
# Source SSH settings, if applicable
if [ -f "${SSH_ENV}" ]; then
source "${SSH_ENV}" > /dev/null
agent_pid=$(pgrep ssh-agent)
(( ${agent_pid:-0} == $SSH_AGENT_PID )) || start_agent
unset agent_pid
else
start_agent
fi
fi
