Exercise 1 Solution

The first two apropos commands return far too much information to be useful. The third command, apropos "copy file" returns a reasonable amount of information.

Macintosh:~ sample$ apropos "copy file"
CpMac(1), /usr/bin/CpMac(1) - copy files preserving metadata and forks
File::Copy(3pm)          - Copy files or filehandles
cp(1)                    - copy files
cpio(1)                  - copy files to and from archives

From this result, you might surmise that CpMac, cp, or cpio would be an appropriate tool for copying files. Of course, the manual entry for each command provides more helpful information.

Exercise 2 Solution

The command man -k "copy file" is equivalent to apropos "copy file" and yields the same results as Exercise 1.

5. Switch to Stickies and use the application. Type some notes, change the color a few times, and do the usual things you do with Stickies. ...
