Michael,
Thank you for this short lesson in Linux. This information is very helpful.
How do you access the CD-ROM drive? Where is it mounted by default? Do you
have to mount it manually?
Right now I am trying to master the command line interface a little before
moving into Gnome. I never could get my sound conflicts worked out between
the command line and Gnome.
Thanks again so much for your help.
Best regards from Ohio, U.S.A.,
Vic

Variable
Hello,
May be time for the lesson on Linux (generally unix) files and where to
expect to find them.
Normally files in /etc and subdirectories are system wide configuration
files, so the file etc/bash.bashrc is the system wide configuation for
bash environments. If you don't have a ~/.bashrc file then you can
create one so that you have a user specific bash configuration. There
are other configuration files you possibly could use, I think the bashrc
files are specific to bash so would not help if you switched to zsh for
your shell, however I won't cover those files now as it might cause
confusion.
The above pattern of having a system configuration in /etc/ and a user
specific configuration in ~/ is very common with unix software.
Other useful directories:
/usr/local/, this tends to be a space for software you compile, the
subdirectories reflect the /usr subdirectories and have a similar
meaning but usually for software you have compiled yourself.
/usr/, this is for system software, normally provided by your distribution.
/usr/lib/, the location for the library files, things like the shared
object (.so) files (similar to dll on windows).
/usr/bin/, the directory for executables.
/usr/sbin/, this one I don't know what the full difference is but I
think its more that things for sysadmin work is in this directory rather
than /usr/bin/
/usr/share/, a directory for data files of installed software (eg.
liblouis tables is an example).
/etc/, the system configuration directory.
/var/, directory for things like log files (normally /var/log/), lock
information of applications using resources (normally /var/lock/) and
run information should only one instance of an application be running
(normally /var/run/). There probably are other subdirectories and other
uses but I think these are the main ones.
/home/, where user directories will be placed.
/dev/, access to the system devices, everything in Linux tends to be a
file, even devices.
/sys/, access to certain system settings, these normally are not
configuration files but active settings (eg. altering a setting on the
kernel, when altered change is immediate). Although not configuration
files, still file access as unix treats most things as files.
I think that has covered the main ones, others may exist and of course
one could configure a system to go against this convention (eg. on the
Mac some directories are different, user directories are in /users/).
As for searching the system, you can use tools which actively get
current files, eg. the ls command (similar to dir in windows). However
if you were to do a full system search, this can be very slow, so you
might want to look into tools which index files and so make searching
faster (the locate command is such a tool). Also gnome probably has its
own search tools, but I am just discussing the command line ones here.
I hope this has helped you.

John,
Is there a way to search a file system tree for a specific file?
I can't find a .bashrc file. I found a file called /etc/bash.bashrc. Would
that be it?
Is pkgconfig a file or a directory? My /usr/local/lib directory is empty.
How else would I find out what to set this variable to?
My errors from configure were:
./configure: line 13558: syntax error near unexpected token
`BASE_DEPENDENCIES,'
./configure: line 13558: `PKG_CHECK_MODULES(BASE_DEPENDENCIES, liblouis
libxml$
Where do I go from here?

Variable
This variable tells the configure script where to find dependencies. You
should add a line like this to your .bashrc file and then log out and
log back in.
export PKG_CONFIG_PATH=/devel/lib/pkgconfig
The part after the = sign is system dependent. I can't say what it would
be on your system, but it might be /usr/local/lib/pkgconfig
