我需要输入 CNTRL C 然后我需要输入yes, 才能接受许可证
现在我正在考虑如何自动化这个过程
我们可以通过运行 sh 脚本并输入CNTRL C然后输入 yes 来自动化此过程吗？
sh CentOS-7.0.1406.libcurl.20180621.x86_64.sh

END OF TERMS AND CONDITIONS
Do you agree with the License? [yes/no]
到目前为止我所做的是：
sh CentOS-7.0.1406.libcurl.20180621.x86_64.sh < < trap ctrl_c INT >/dev/null < <(echo y)
但这种方法不起作用
Perl/python oneliner 行也是预期的
预期结果示例：
Do you agree with the License? [yes/no] yes
Extracting . . .
lib-4.0.20-20180619.x86_64.rpm
lib-devel-4.0.20-20180619.x86_64.rpm
Extract completed. Continue installation by installing the RPM
重要的提示
我能说的是，当我运行脚本并执行 CNTRL C 时，我立即得到关于 yes 的问题
答案1
你可能应该使用expect对于此类任务。
但是，作为一个快速而肮脏的拼凑，你可以使用script(1)作为一个迷你期望：
{ sleep .3; printf '\003'; sleep .3; printf 'y\r'; ...other prompt responses...; } |
script -q /dev/null -c 'sh that_installer.sh'
\003是 Control-C，\r是 Return/Control-M 等。
