How to answer yes in Bash Script
提问by Vor
Have a quick question,
有一个快速的问题，
imagine that I have this code:
想象一下，我有这个代码：
mkdir -p $INSTALLDIR
sudo apt-get install -y git clojure leiningen
git clone git://github.com/maltoe/storm-install.git
./storm-install/storm_install.sh all `hostname` $INSTALLDIR
And this script will ask, do you want to install additional packages, and I want to say yes,
How to do this automatically?
这个脚本会问，你想安装额外的包，我想说yes，如何自动执行此操作？
Or may be there is a way to kinda answer yes to any question by default?
或者可能有一种方法可以在默认情况下对任何问题回答“是”？

assume storm asks the question - use a here document - example:
假设风暴问这个问题 - 使用这里的文档 - 示例：
mkdir -p $INSTALLDIR
sudo apt-get install -y git clojure leiningen
git clone git://github.com/maltoe/storm-install.git
./storm-install/storm_install.sh all `hostname` $INSTALLDIR <<-EOF
yes
EOF
The EOF can be any nonsense characters the shell will not interpret.
EOF 可以是 shell 不会解释的任何无意义字符。

apthas also --force-yesoption which may be helpful:
apt还有--force-yes可能有帮助的选项：
--force-yes
Force yes; This is a dangerous option that will cause apt to
continue without prompting if it is doing something potentially
harmful. It should not be used except in very special situations.
Using force-yes can potentially destroy your system! Configuration
Item: APT::Get::force-yes.

I have a script needs to pass "yes" for couple of times and at last we need to pass "version number" in order to deploy in to the nexus. Any suggestions?
我有一个脚本需要多次传递“是”，最后我们需要传递“版本号”才能部署到关系中。有什么建议？
