直白地说 注释掉 一段代码 我做

: | | { 块 的代码 ｝

你对此有什么看法?

function giveitauniquename()
{
  so this is a comment
  echo "there's no need to further escape apostrophes/etc if you are commenting your code this way"
  the drawback is it will be stored in memory as a function as long as your script runs unless you explicitly unset it
  only valid-ish bash allowed inside for instance these would not work without the "pound" signs:
  1, for #((
  2, this #wouldn't work either
  function giveitadifferentuniquename()
  {
    echo nestable
  }
}

直白地说 注释掉 一段代码 我做

: | | { 块 的代码 ｝

我尝试了选择的答案，但发现当我运行一个shell脚本时，整个事情都打印到屏幕上(类似于jupyter笔记本如何打印出“xx”引号中的所有内容)，并在结束时出现错误消息。它什么都没做，但是很吓人。后来我在编辑的时候意识到单引号可以跨越多行。所以. .让我们把这个块赋值给一个变量。

x='
echo "these lines will all become comments."
echo "just make sure you don_t use single-quotes!"

ls -l
date

'

在阅读了其他答案后，我想出了以下答案，恕我直言，这是一个评论。特别适合脚本内使用信息:

<< ////

Usage:
This script launches a spaceship to the moon. It's doing so by 
leveraging the power of the Fifth Element, AKA Leeloo.
Will only work if you're Bruce Willis or a relative of Milla Jovovich.

////

作为一名程序员，斜杠的序列会立即在我的大脑中注册为注释(尽管斜杠通常用于行注释)。

当然，“////”只是一个字符串;前缀和后缀中的斜杠个数必须相等。

简单的解决方案，不太聪明:

暂时阻塞脚本的一部分:

if false; then
    while you respect syntax a bit, please
    do write here (almost) whatever you want.
    but when you are
    done # write
fi

稍微复杂一点的版本:

time_of_debug=false # Let's set this variable at the beginning of a script

if $time_of_debug; then # in a middle of the script  
    echo I keep this code aside until there is the time of debug!
fi
