我正在嘗試下載 teampeak 3 用戶端並同時接受許可協議例程。我知道如何在腳本之前傳遞“是”，但例程要求我在單擊按鍵開始解壓縮客戶端Q之前按退出“許可協議” 。Y
#!/bin/bash
cd /home/test/ts3_client_files
wget http://dl.4players.de/ts/releases/3.0.19.4/TeamSpeak3-Client-linux_amd64-3.0.19.4.run
yes 'y' | ./TeamSpeak3-Client-linux_amd64-3.0.19.4.run
正如您所看到的，該例程需要先按下Q。當我按 時Q，Y會自動按 並解壓縮檔案。

答案1
按鍵q作為 pager 的退出訊號less，由腳本明確使用：
read FOO
echo "$licensetxt" | less
while true
do
MS_Printf "Please type y to accept, n otherwise: "
read yn
if test x"$yn" = xn; then
keep=n
eval $finish; exit 1
break;
elif test x"$yn" = xy; then
break;
fi
done
和man less說：
選項也取自環境變數“LESS”。
設定此環境變數如下：
printf '\ny\n' | LESS='+q' ./TeamSpeak3-Client-linux_amd64-3.0.19.4.run
