"This is, however, the bread and butter of shell programming."
This is really old-fashioned thinking. The people who have been in this industry for 10+ years all grew up without computers - and thus had to memorize all of the flags, obscure shell commands, and weird regular expression. What was taught in school back then was to do things perfectly the first time, because CPU cycles were expensive, and bugs were time consuming.
The generation that graduated from college about 2 years ago is the first one that had universal access to a search engine since they knew how to use a computer. This generation (and all future ones for the rest of time) sees memorizing things like this as more of a waste of mental space. What is taught in Universities now is problem solving, research, and larger concepts. There is very little straight memorization, and almost zero programming by hand/whiteboard programming. No current college grad will be able to write a shell script without reference material, but every college grab should be able to write any simple script in less than 5 minutes with Google.

Unix command line is a boon for problem solving and experimentation, just go and read Jon Bentley's _Programming Pearls_. One can't Google for what one doesn't realise can be done.
- kragen 14y agoYou're going to have a hard time making it through Hemingway if you have to reach for a dictionary every time you come across a word like "middleweight" or "khaki", even if your dictionary is online and answers your query in less than a second. You need to memorize the meanings of a vocabulary of words in order to read fluently or write well. That's not "old-fashioned thinking". It's just common sense. And it's just as true of shell scripts as it is of electrical engineering, mechanical engineering, poetry, or math.

- iheartfisting 14y agoTotally agree with this. If people don't want to learn how to be fluent and proficient with their tools, they should just buy some nicely packaged product and leave the thinking to people who do.
