- In Bash, whether to use single or double quotes depends on exactly what you want to do, and the differences can trip you up if you're not concentrating. Here's a quick rundown of what each does and when to use them.
- I have seen many new Linux system administrator without any clue about file system.
- There are different flavors of shells, just as there are different flavors of operating systems.
- A good shell script will have comments, preceded by a pound sign, #, describing the steps.
- A user's PATH consists of a series of colon-separated absolute paths that are stored in plain text files.
- A table-driven method is a scheme that allows you to look up information in a table rather than using logic statements (if and case) to figure it out.
- Things to look out for! Gotchas!
- Rote learning or learning by rote is learning things by repeating them without thinking about them or trying to understand them.
- I like to tell people that my book gives you your "programming black belt."
- It's inevitable; even seasoned programmers would make a few.
- Do Not Copy-Paste
- If you break the problem down into small exercises and lessons, and do them every day, you can learn to do almost anything.
- As you study this book, and continue with programming, remember that anything worth doing is difficult at first.
- Then one day BANG your brain will snap and you will suddenly "get it."
- If you give up, you won't ever reach this point.
- If you go through this whole book, and you still do not understand how to code, at least you gave it a shot.
- give it a shot/whirl
(informal) to attempt to do something I've never danced salsa before but I'll give it a shot.
See also: give, it, shot - If you think you are smarter than me, then you will feel talked down to and there's nothing I can do about that because you are not my intended reader.
- Don't listen to them and do the exercises anyway so that you learn how to educate yourself.
- "at your expense" means that you will have to pay. In this context, it is not meant in the literal sense of paying money, I suspect, but rather that "you will suffer" in some unspecified way.
