Automate pressing enter key inside of bash script
提问by user2548441
I have a Bash script where I try to wget a repo for which I have to press enter for a very long Eula text, literally I have to manually press enter key 20+ times and then type yes. Can someone please help me to automate pressing enter key and at the end enter yes in bash script.
我有一个 Bash 脚本，我尝试在其中获取一个 repo，我必须按 Enter 键输入很长的 Eula 文本，实际上我必须手动按 Enter 键 20 次以上，然后键入 yes。有人可以帮我自动按下回车键，最后在 bash 脚本中输入 yes。
yes "" | command
and
和
echo -ne '\n' | <command>
doesn't work for me, I still have to manually press enter key.
对我不起作用，我仍然必须手动按 Enter 键。
Here is the code, so when it runs wget, I need to keep pressing enter till it ask if you want to accept the license and there I enter "yes".
这是代码，所以当它运行 wget 时，我需要一直按 Enter 直到它询问您是否要接受许可证，然后我输入“是”。
#!/bin/bash
pid=$(ps aux | grep xxx-server |grep -v grep | awk '{print }')
if [ -n "$pid" ]; then
kill $pid
echo -e "\n$pid killed -Success"
fi
# Check if the package already installed then remove it
if [ `dpkg -l | grep xxx-server | wc -l` -gt "0" ]
then
apt-get -y remove xxx-server
fi
# wget the repo using silent install
if [ "apt-cache search xxx-server" ];then
#if [ $? != 0 ] ; then
echo -e "\nremoving repo ...."
#aptitude install $i -y > /dev/null
apt-get purge xxx-server-repo-* -y > /dev/null
echo -e "\nInstalling Reop .........."
yes "" | wget -q -O - http://xxx-server.com/ | sh
fi

I don't know what are you trying to do, you'd better show us some code! But most probably you want to use expect:
我不知道你想做什么，你最好向我们展示一些代码！但很可能你想使用期望：
#!/usr/bin/expect
spawn "yourscript"
for {set i 0} {$i < 20} {incr i 1} {
send "\n"
}
send "yes\n"

Even though the question is pretty old. This answer might help someone.
尽管这个问题已经很老了。这个答案可能对某人有所帮助。
you can use this to supply input to your scripts.
您可以使用它为您的脚本提供输入。
cat <(echo "yes") | "Your_Command"
