您好我有一个我正在创建工作的脚本，并被要求添加一个功能以实现可伸缩性。我目前在每次请求后暂停，但我不知道如何添加跳过暂停功能。我留下了我的代码，以显示我正在做的提供更多信息的基本功能。在顶部我主要有函数，在底部是函数动作和暂停。

将您的pause函数更改为返回0（true）以跳过，或1（false）继续，并将其重命名为更具描述性的内容：
function shouldSkip {
read -p "$*" line
test "$line" = 'n' -o "$line" = 's'
return $?
}
使用：
if ! shouldSkip 'Press [Enter] key to continue, [n] or [s] to skip "service ipmi start". ..'
then
service ipmi start
fi

特别感谢Danny Dagla。发布最终脚本供全球使用。
