```rust
#[test]
fn false_not_ok() {
let mut cmd = Command::cargo_bin("false").unwrap();
cmd.assert().failure();
}
```
This test fails
Note from the Author or Editor:
I cannot see how this test fails for you. It definitely works for me. Are you sure that your "false" program is correctly reporting a nonzero exit value? |

2nd paragraph |
"Both a filehandle and std::io::stdin implement the BufRead trait"
In fact, filehandle and std::io::stdin only implement the Read trait.
A BufReader is created subsequently which is implemented for the Read trait. BufReader in turn implements the BufRead trait which provides the BufRead::lines method.

3rd block of text, starting with "I want to highlight" |
This sentence:
> I want to highlight how I create a temporary list using a slice with all the flags.
refers to this code:
> [args.words, args.bytes, args.chars, args.lines]
From what I can tell this is an array, not a slice. By attempting to call a non-existent method on it I get an error like this one:
no method named `taco` found for array `[bool; 4]` in the current scope
method not found in `[bool; 4]`

Setting up the delimiter argument |
The long flag name for delimiter is incorrectly written as "delim" and should instead be "delimiter".
As listed in the book:
.arg(
Arg::new("delimiter")
.value_name("DELIMITER")
.short('d')
.long("delim")
.help("Field delimiter")
.default_value("\t"),
)
It should instead be:
.arg(
Arg::new("delimiter")
.value_name("DELIMITER")
.short('d')
.long("delimiter")
.help("Field delimiter")
.default_value("\t"),
)
