I love shell scripts because they’re so pragmatic and often allow me to get jobs done really quickly.
But sadly they’re full of pitfalls. Pitfalls everywhere you look.
Today, a coworker – who’s highly skilled, not a newbie by any means – ran into this:
$ bash -c 'set -u; foo=bar; if [[ "$foo" -eq "bar" ]]; then echo it matches; fi'
bash: line 1: bar: unbound variable
Why’s that happening? I know the answer. Do you? 😂
Stuff like that made me stop using shell scripts at work, unless they’re just 4 or 5 lines of absolutely trivial code. It’s now Python instead, even though the code is often much longer and clunkier, but at least people will understand it more easily and not trip over it when they make a tiny change.

为什么草莓这种水果一旦做成果汁或零食，味道闻起来没有那么清新？甚至有点臭臭的？
这不是题主自己的问题，是因为两种「草莓味」确实有差异。这个差异可能由两种因素造成：
- 草莓本身，在进行热加工的过程中，风味就会变化、损失。
- 有些草莓果汁饮料、草莓饼干中的「草莓味」可能主要来自草莓香精而不是草莓本身。香精的味道很难达到 100% 的相似程度。
下面分别详细阐述一下。
1. 「草莓味」到底包括哪些物质？我们能吃到「草莓味」，本质上是因为草莓里富含各种各样的挥发性的香气物质，这些香气物质进入鼻腔以后，分别刺激不同的嗅细胞，神经信号传导到大脑的嗅觉中枢，我们就会闻到「草莓味」。
那么，草莓本身的特征香气物质有哪些呢？其实相当复杂。有研究在 20 种不同的草莓中发现了共 181 种特征性的风味化合物[1]。它们包括：
- 酯类物质： 包括丁酸乙酯、乙酸乙酯、己酸乙酯等。这些酯类物质给草莓带来了特征性的果香和花香。
- 萜烯类物质： 如芳樟醇、 … ⌘ Read more

那么，如何对人体所受伤害的严重程度进行评价呢？
总体而言，人体伤害一般分为两个评价维度：第一，人体各部位所能承受的机械载荷限值。第二，根据伤害风险曲线来判断载荷作用下发生伤害的可能性。
