Well, I am not real knowledgeable about computers but I have still an old Toshiba 1000
that I bought for $150 in 1993 at a hamfest. I used it for packet radio for awhile. It
had a 3 1/2 " internal drive and I bought a 5 1/4" external that came with a big
brick power supply for $50 dollars for it.
I think the Toshiba 1100 was really about the same thing.
When I was looking for a 5 1/4" drive in 1993, I remember people telling me that
MicroSolutions made one for various notebook computers. I think I have the name of the
company correct. MicroSolutions also made external hard drives and tape drives they
called/call the back-pack I think.
My Toshiba works,err, maybe worked, with its own connections. I think the MicroSolution
stuff was all parallel port.
I have always wondered if somebody has written a driver for my parallel port 100 Mb Zip
drive to work with the old XT type Toshiba 1000? That might be an interesting solution
for you also.

New subject: Really OT: Any tar experts here?
Sorry for the off-topic post, but I'm tired of beating what's left of my
brains on what's left of my desk... Please, Please, Please, private email
replies only.
Non-essential info: I'm writing a selective backup program in Perl to read
a config file, use the info to create a list of directories to be backed
up, then give that listing to tar to back up the information.
Essential info: Problem is, I have directories that I want backed up, but
with subdirectories that I *don't* want backed up; yet when I feed the list
of dir's to tar, it recursively backs up the dir's anyway.
Is there a way (program switch, special version of tar, anything...) to
tell tar to not recurse subdirectories, or do I need to write a sub-program
that extracts each individual filename?
Thanks in advance for any help that can be provided.

I'm inclined to say post it to the list, even if it is off-topic, as I'd
also be interested.

Well if you're going to be that way about it.
Short answer : use CPIO
Long answer : specify all the leafs and don't specify
any directories.
Longer answer : ../src/gnu/usr.bin/tar
make it do anything you want :-)

A good choice, since it's so widely compatible and is very flexible. Nice
for backups to tapes because you can specify 5120 bytes/record input
blocks. Also nice because you can actually do *full* backups with things
like device files, etc (tar won't do device files). I think the most
important thing, though, is the recovery from bad blocks - which kills a
tar restore...

Now you're talking...

As always with Unix, there's eight ways to skin the cat, and sixteen
if you're god-like enough to write C programs with 'cat'.
I think the easy way would be to write your Perl or shell script
that assembles the list of files to backup, with absolute or relative
paths as needed, and write those filenames to a file, then tell
'tar' to read its names from that text file instead of trying to trick
its recursion into doing the right thing.
This makes the problem more chunkable and more easily debugged, too.

Roger,
Are you using gnu tar? You might want to...you should be able to use the
-T (include files list) and -X (exclude files list) options for this.
Like: system("/usr/bin/tar -T ./include.list -X ./exclude.list");
Or sans shell:
$result=system("/usr/bin/tar", "-T ./include.list",
"-X./exclude.list");
For dumb versions of tar, you can probably get creative with executing cat
as a subshell (inside backquotes) like: $tar cvf backupfile.tar `cat
include.list` or some such rubbish. If you do that, you can cheat and use
the tee command (if it's on your system...) to split the piped output into
a results file. I'm sure there are more elegant solutions, but what do you
want after a couple-of-few pints of Guinness?
I personally use the Archive::Tar module for this kind of thing though:
ftp://cpan.nas.nasa.gov/pub/perl/CPAN/modules/by-module/Archive
Have fun!
