Just a small note:
The book states "Notice that it starts renumbering the lines for each file" in regards to using "cat -n" with multiple files. I think the GNU version of cat works differently as it does not restart the numbering for each file, it just continues counting up.
Not a big deal but if one tries to make their own expected results instead of copying it from the github, one could get different results on linux, causing the tests to fail.

Note from the Author or Editor:
I've made a note that I'm showing the BSD version, which is the output expected by the tests and that the GNU version works differently.

I believe this sentence "return the Err variant of Option to the caller" should be "return the Err variant of Result to the caller"

Note from the Author or Editor:
Thank you for the report. I've corrected the text.

3rd paragraph

chapter 3 is building "catr" program but it is referred to in the tutorial as "echor", the previous program.

same error again on page 51.

Very minor nit but it caused me to expect we were rewriting echor with the new lib approach before continuing on to catr - so some flipping back and forth.

great book, btw - fantastic teaching approach.

Note from the Author or Editor:
Confirmed and fixed. Thanks for the report.

10th paragraph

"As mentioned in Chapter 3, bytes may equate to characters for ASCII, but Unicode characters may require multiple bytes. The file tests/inputs/atlamal.txt contains many such examples:"

Chapter 3 -> Chapter 4

Based on the content, this sentence seems to relate to Chapter 4, not Chapter 3.

Note from the Author or Editor:
Fixed. Thank you.
