Figure P-1

Given that "-- opt" appears in the explanatory text that follows, and that there are five, not "six properties" listed, it should be included in Figure P-1.

Note from the Author or Editor:
Yes, "-- opt" is missing from figure P-1 and should be added.

The output produced by "-> type who" is correct - assuming that the command was not previously run in the current shell. If, as suggested by "-> who" on the previous page, it was, the output would be "who is hashed: (/usr/bin/who)"

Note from the Author or Editor:
In a future printing, we'll show both the hashed and unhashed response.

In the first Kindle release dated 2024-03-01, the text in some tables is badly split across multiple lines when it should fit on a single line. For example, the word "less" might appear as "le" on one line and "ss" on the next line. This line-wrapping issue is found ONLY on Kindle, not in other digital formats or paperback. O'Reilly has issued an update to mitigate the issue. View page 3, "Revision History for the Fourth Edition." If you see just one entry, "2024-03-01: First Release," then update the book on your Kindle to fix the issue. If you see entries for 2024-04-19 or later, then your book is updated.

commands

The command "sleep 120 &" would display the PID, making the "pgrep sleep" command redundant.

Note from the Author or Editor:
The output of "sleep 120 &" would be something like "[1] 2673" showing the PID, meaning the pkill command is unnecessary. This will be fixed in a future printing.
