sh + how to send cntrl c 然後輸入 yes 接受許可

我需要輸入 CNTRL C 然後我需要輸入yes，才能接受許可證

現在我正在考慮如何自動化這個過程

我們可以通過執行 sh 腳本並輸入CNTRL C然後輸入 yes 來自動化這個過程嗎？

sh  CentOS-7.0.1406.libcurl.20180621.x86_64.sh

Do you agree with the License? [yes/no]

到目前為止我所做的是：

 sh  CentOS-7.0.1406.libcurl.20180621.x86_64.sh < < trap ctrl_c INT >/dev/null < <(echo y)

但這種方法不起作用

Perl/python 單線也是預期的

預期結果範例：

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

我能說的是，當我執行腳本並執行 CNTRL C 時，我馬上就會得到關於是的問題

您可能應該將expect其用於此類任務。

但是，作為一個快速而骯髒的組合，你可以script(1)用作一個小期望：

{ 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，等等。
