To quote or not

My question is, "Do I not understand, or is my information out of date?"
I am trying to just be a student, rtfm'ing. I am working on my work systems. Is it simply that the book was printed in 2002 and a lot has changed since then, or did I miss something?

Working in Korn Shell.
I have been reading O'Reilly "Learning the Korn Shell." (Which deals with ksh93)
We have Version M-11/16/88f, not 93.

I was reading about quoting, and the book cited an example using the 'find' command. It states that I need to quote wildcards used in the find command. It also says I need to use "-print" to see the results.

I use the find command a lot. I have neither been quoting/escaping, nor using -print, but I get what I am looking for:
Code:

I am not being deliberately thick. I am inclined to assume, "old book, old shell, it works how it works, move on..."
But, I have hamstrung myself in the past by carrying around half-misunderstood concepts. Quoting and regex are things that are fuzzy to me, and I want to get them straight.

halt(8) 						      System Manager's Manual							   halt(8)

NAME
halt - Stops the processor SYNOPSIS
/usr/sbin/halt [-d] [-l] [-n] [-q] [-y] DESCRIPTION
If other users are logged into the system, or if the system is operating at a multiuser run level, use the /usr/sbin/shutdown -h command to halt the system. If only the root user is logged in, and you do not plan to restart the system immediately, use the halt command. The halt command writes data to the disks and then stops the processor(s), but does not reboot the machine. You must be the root user to run this command. When the system displays the ....Halt completed.... message, you can turn off power to the machine. If the command is invoked without the -l, -n, or -q flag, the halt program logs the shutdown using the syslogd command and places a record of the shutdown in the login accounting file, /var/adm/wtmp. Using the -q and the -n flags imply the -l flag. FLAGS
Generates a crash dump of the system before halting it. Can be used with any other flag. Does not log the halt using syslog Prevents the sync before stopping, and does not log the halt using syslog Causes a quick halt, does not log the halt using syslog, and makes no attempt to kill all processes Halts the system from a dial-up operation EXAMPLES
To halt the system without logging the shutdown in the log file, enter: halt -l To halt the system quickly, enter: halt -q To halt the sys- tem quickly, also leaving a crash dump for the savecore command, enter: halt -d -q To halt the system from a dial-up, enter: halt -y FILES
Specifies the command path Specifies the syslog daemon Specifies the login accounting file RELATED INFORMATION
Commands: fasthalt(8), reboot(8), savecore(8), shutdown(8), syslogd(8) Functions: reboot(2), sync(2), syslog(3) delim off halt(8)
