in thread How to grep exact string

Yes, but this method is not clearly superior if arrays are needed for other purposes. The array comparison is simpler, uses less memory, and will be fast unless both files are huge.

    Or, as Darth put it:

    The time to build the structure is insignificant compared to the power of the hash!

    The code to implement the hash version isn't significantly more complex - see the version in another nodelet for how it would go.

[stevieb]: choroba my GPS home device is done, at least prototype v1 is. I'm just making sure all of my code does what it says now
[stevieb]: I test/prototype code on my Pi, then I migrate it over to Arduino when it's ready (if that's a better platform for what I'm doing). The whole RPi stuff was for learning at first, then it snowballed. I'm just trying to get my in-house CI...
[stevieb]: ...done, which obviously requires a specific hardware setup.
[stevieb]: I don't write tests for the lower-level distributions (ie. ICs, sensors etc) within those distributions, I have all tests in a master distribution which encompasess all of the sub-modules
