bug in exercise 2 in chapter 1?
Exercise 2 in chapter 1 states that the commands:
man -k "copy file"
and
apropos "copy file"
return equivalent results. I found this not to be the case. I've tried this on two Macs, both running OS 10.4.6
I've copied the results from my terminal below. When I use the command:
apropos "copy file" I get a short response as follows:
================================================== ====================
bluewater:~ swartout$ apropos "copy file"
CpMac(1), /Developer/Tools/CpMac(1) - copy files preserving metadata and forks
File::Copy(3pm) - Copy files or filehandles
cp(1) - copy files
cpio(1) - copy file archives in and out
ditto(1) - copy files and directories to a destination directory
bluewater:~ swartout$
================================================== ===================
But when I use the command
man -k "copy file"
I get a much longer response, which I have truncated below:
================================================== ====================
bluewater:~ swartout$ man -k "copy file"
CpMac(1), /Developer/Tools/CpMac(1) - copy files preserving metadata and forks

The results don't seem to be equivalent to me....what am I missing?
Thanks for your help.
