自动在命令行上的Y之前传递“q”
我正在尝试下载teamspeak 3客户端并同时接受许可协议例程。 我知道如何在脚本之前传递“是”，但例程要求我按Q退出“许可协议”，然后单击Y键开始解压缩客户端。
#!/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 如您所见，例程需要先按Q。 当我按下Q时 ，会自动按下Y并解压缩文件。

有人会如此善良地向我展示道路吗？
q keypress用作寻呼机的退出信号，由脚本明确使用：
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
man less ：
选项也取自环境变量“LESS”。
设置此环境变量如下：
printf '\ny\n' | LESS='+q' ./TeamSpeak3-Client-linux_amd64-3.0.19.4.run
