1. Example 1: If a 1000-Ω resistor is connected in parallel with a3000-Ω resistor, what is the total or equivalent resistance?

Withthis law, and Ohm’s law, you come up with the current divider

Great intro problem to Kirchhoff's current law

Current divider notes as well!

1. A falsey return value from #validate will deviate the flow and go straight to End.fail_fast.

Similar to: How, in Rails, aborting a before_action causes all later ones to be skipped.

1. Important caveat: in the combined expression, if the middle command has a non-zero exit status, then both the middle and the rightmost command end up getting executed.

I don't think that is surprising, is it? Since && and || have the same order of precedence. So I think this is more of a clarification than a caveat.

I think this is just because:

a && b || c is equivalent to: (a && b) || c (so of course c gets evaluated if `(a && b)` is false (that if either `a` or `b` is false).

I think they just mean, in this case:

``````bedmap && mv || fail
``````

if `mv` fails, then `fail` still gets executed.

Easier to see with a simpler example:

``````⟫ true && false || echo 'fail'
fail

⟫ false && true || echo 'fail'
fail
``````

Better example/explanation here: https://hyp.is/-foxmCVXEeuhnLM-le_R4w/mywiki.wooledge.org/BashPitfalls

The caveat/mistake here is if you treat it / think that it is equivalent to if a then b else c. That is not the case if b has any chance of failing.

1. The potential problem: if second_task fails, third_task will not run, and execution will continue to the next line of code - next_task, in this example. This may be exactly the behavior you want. Alternatively, you may be intending that if second_task fails, the script should immediately exit with its error code. In this case, the best choice is to use a block - i.e., curly braces: first_task && { second_task third_task } next_task Because we are using the -e option, if second_task fails, the script immediately exits.
2. When people write COND && COMMAND, typically they mean "if COND succeeds (or is boolean true), then execute COMMAND. Regardless, proceed to the next line of the script." It's a very convenient shorthand for a full "if/then/fi" clause.
