你好，我有一个脚本，我正在为工作创建，并被要求添加一个可伸缩性的功能。目前，我在每次请求后都会暂停，但我不知道如何添加跳过暂停功能。我留下了我的代码，以显示我正在做的事情的基本功能，以提供进一步的信息。在顶部，我主要有函数，在底部是函数、动作和暂停。

将pause函数更改为返回0 (true)跳过，或返回1 (false)继续，并将其重命名为更具描述性的名称：

function shouldSkip {
  read -p "$*" line
  test "$line" = 'n' -o "$line" = 's'
  return $?
}

要使用以下命令：

if ! shouldSkip 'Press [Enter] key to continue, [n] or [s] to skip "service ipmi start". ..'
then
  service ipmi start
fi
