在命令行上，在 Y 之前自动传递“q”

在命令行上，在 Y 之前自动传递“q”

我正在尝试同时下载teamspeak 3客户端并接受许可协议例程。我知道如何在脚本前输入“是”，但例程要求我先按Q退出“许可协议”，然后再单击Y开始解压客户端的键。

#!/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，该例程要求先按下Q。当我按下 时Q，Y然后自动按下 ，文件就会解压缩。

有人能好心地给我指条路吗？

答案1

该q按键充当分页器的退出信号less，脚本明确使用了该信号：

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说：

选项也取自环境变量“LESS”。

按如下方式设置此环境变量：

printf '\ny\n' | LESS='+q' ./TeamSpeak3-Client-linux_amd64-3.0.19.4.run
