last paragraph |
Second sentence in the paragraph reads "Left unquoted, $* and $& give you..." but should read "Left unquoted, $* and $@ give you...".
The whole section is about using $@ as opposed to $* . Otherwise, there is no such thing as $& . I was confused by its appearance for about 2 minutes til I searched the book for more instances of the typo and found none, confirming my suspicion that it was in fact just a typo.
Note from the Author or Editor:
Correct, and nice catch, thanks. I've fix that in the Atlas repo. |

code in solution |
The if test is like this
if [ -f "$SCRIPT" -a -x "$SCRIPT" ]
But in the main text we have -f and -x.
Note from the Author or Editor:
First, we're really sorry we never got back to this! We try to keep up on errata (we get emails), but somehow a number of them slipped through.
The code is correct, but I see we failed to clarify that the `-a` is an "and" in the test. I just changed it to `...If it is a file (the ++-f++ test) _and_ (++-a++) has execute permissions ...`, thanks for the report. |

The name of the variable is $# but is shown in the text as ${}.
Notice this is the same error as posted by Andy Lester on Jan 09, 2020.

This is verified, and it's a known issue we have with how the tool-chain renders Asciidoc, as also note in the "Andy Lester page 112" errata. I just fixed this one also, and looked for others but didn't find any. Thanks for the report! |

Table 6-1 |
expected: ' |= Bitwise “or” a|=b a=(a|b)'
printed: ' \ = Bitwise “or” a|=b '

This is verified, its a bug in our Asciidoc table code, I just fixed it. It really throws that table off, so thanks for the report!
The diff is:
-|++\++|=|Bitwise "or"|++a\|=b++|++a=(a\|b)++
+|++\|=++|Bitwise "or"|++a\|=b++|++a=(a\|b)++
The correct table row should be:
|= Bitwise "or" a|=b a=(a|b) |

The name of the variable is $# but is shown in the text as ${}. Later, it's either $# or ${#}.

This is verified, and it's a known issue we have with how the tool-chain renders Asciidoc. :-( We even have a FIXME in the source about that, but we missed the one you mention. I just changed the sourcea from `++${#}++` to the simpler ++$#++ which as noted works elsewhere. The `++${#}+` version tat works is ` ++${#}++`. (Sigh.)
Thanks for the report! |

"You can also use the xarg command."
"xarg" should be "xargs"
