GnuCash (http://www.gnucash.org/) has some Income Tax related
features.  Maybe useful?

Thanks for the reply.  I'm quite unfamiliar with both XSETTINGS and
fontconfig, and would like to translate the difference between Chrome
and Iceweasel (that you point out) into improvement in Iceweasel's
font-handling.  Wonder if there's some documentation on this?  

Thanks,

My assistance at this point will be rather limited, as I've never used

Being that it fails intermittently and it seems to fail while querying
your own name server, I have a feeling the problem is with dnsmasq.

Rather than using "host", try using nslookup, but don't use it in the
same way you're using host.  Instead, type nslookup by itself to enter
its command shell.  From there, when you perform a lookup, it will
tell you which server it's querying to obtain the answer.

Non-authoritative answer:

In my example, my box is querying my internal DNS server on 10.10.2.25
to obtain the answer.  Run the same query against your local host
multiple times to see how persistent the problem is.  Once you've done
that, switch to query against a separate server and run the query
against it multiple times.

cannot install to AMD Geode LX800 machine

[Hideki Yamane]

Hi,

 I was asked from a user who want to install Debian but I couldn't solve 
 his problem, so I want your help.

 He uses "Kojinsha SA5ST12A", it has AMD Geode LX800 chip.
 
http://jp.kohjinsha.com/support/content/supt/sa/sa5st12a/specification/index.html
 (Japanese)

 He tried to install with debian-503-i386-businesscard.iso but the screen 
 comes to blank with white. ( http://www.youtube.com/watch?v=0sRZ2Bup6ks )

 I suggested to use "fb=false" as release note says, but it seems not to help.
 http://www.debian.org/releases/stable/i386/ch05s03.html.ja#installer-args

 If you have any suggestions about above problem, please let me know.
 (Please CC to me, I'm not on the list)

Well, as Mr. Spock would say,

   Fascinating!

It appears that the combination of a shell pipeline and
fifos makes the implementation of a multi-streamed pipeline
possible.  The problem is the lack of "stages",
especially the stream splitting and stream joining ones.

Thank you, Bob and Boyd, for your insights and expertise.

It is running dnsmasq. It's a gateway and firewall with two NICs, one for the

I don't know why the first lookup is failing with the default nameserver from my 
ISP - but it only fails intermittently.


I have a small hunch that it might be to do with my setup because the external

so. I just don't know what to check for next. There is no other website I have

As noted in some earlier posts, using 'tar -f -' causes the archive tar
creates to be written to stdout.

This means the list of file names printed because of the 'v' option,
must be written to some other file descriptor, else it will corrupt the
archive contents.

The "usual" way for an app to do this is to write to stderr, which is
what 'tar' does.

The tar sdtout is already redirected in the initial pipeline.  Putting
the pipeline in parenthesis causes the entire thing to run in a
subshell.  The '2>&1' takes the stderr of the subshell and puts it onto
the stdout of the current shell, which is then redirected by the $(...)
into the variable.

This is a great example as well.  The only problem is bash4 isn't
readily available to people using lenny.  Also, wouldn't he just want
to redirect sdtout and not stderr?  I guess it all depends on what he
wants to do with the list.

As the man page notes, see `info tar`.  The answer is buried in "3.9

I think this is the best method I've seen thus far.  Putting the data
into an array should avoid problems with file names containing spaces.
 I don't understand why he would stderr in it, though.  I'd like to
know what the OP plans to do with the list of processed files.

Can you please explain how it's simpler.  The method I suggested
certainly isn't as easy, but the method I suggested merely showed a
detailed example.  Others here are coming up with 1 or 2 liners that
can do this without having to process the archive a 2nd time.

I don't see how the example you provided puts the list into a
variable.  Would you be so kind as to go into more detail regarding
your suggestion?

I agree that your suggestion would be much clearer, and your
suggestion may suit the needs of the OP.  I suppose it's just my
personal feelings to not sacrifice efficiency for making a script
easier to understand.  Comments can be added to the script to explain
how parts of it function.

Others have recommended stderr.  I'm not sure why.  The method that
would be most effective would be to direct stdout, not stderr.

Not if he uses stdout.  The example shown above only shows what was

Efficiency vs clarity; sometimes it's a personal preference, other
times it may not be.  For example, if I'm passing this script on to
someone else that isn't familiar with the scripting language, I think
clarity would be paramount.  Otherwise, I'd go for efficiency.

The method you suggested is to process the archive a 2nd time to get
the listing, and to use -tv.  That causes more overhead than getting
the list of processed files while the archive is being created.

My point, exactly, though better said ;)

If someone wanted to, they could write a single program that would read
input/write output from/to two or more descriptors, and use it to create
a multi-path'ed I/O processing sequence, but writing it to prevent
blocking on one input/output, so it could continue working on the other
pair, would be a bit hairy.

The fifo node makes this sort of thing easy to do.

I'm just an observer of this conversation, but can you clarify your

I'm curious as to the reason the name can be both resolved and not
found, but I get the same result here, from two machines with completely
different routing and dns (I think).

Thanks for the suggestion. I actually removed the entire keyboard

My example runs in parallel.  It's virtually required when using fifos.  They 
aren't normal files -- only so much data can be written to their internal 
buffer before further writes block.

In this case the shell actually starts at least 6 processes.  One for each 
"utility".  Prior to doing the "exec" call in each process, it sets up the 
pipes and redirection.  It doesn't wait for the processes to finish (notice 
the '&' at the end of the pipelines) until I use the wait shell-builtin.

When the "LOCATE" utility on the second line starts trying to read from stdin 
(LOCM) it will block until the "LOCATE" utility on the second line writes data 
to stderr (LOCM) and more-or-less immediately start working on that data as 
soon as it arrives.  Similarly, "FANINMANY" will block when trying to read 
stderr (FIN) just until the "LOCATE" on the second line writes data out to 
stdout (FIN).

The standard mount script is run in runlevel S, which is entered before
the numbered runlevels which is where cron is started. So I'm guessing
if the device is there in time to be mounted from fstab, it will be
there before cron runs.

I believe the use of fifo's in this context is required.  Unless you're
willing to write the 'LOCATE' and 'FANINANY' tools first, to deal with
inputs on descriptors other than 0, 1 and 2.

Not something I'd care to do, personally. ;)

You might be able to do this using 'exec' to open and redirect the I/O
streams at the shell level, but the nature of the '|' in UNIX/Linux is
to read stdin and write stdout, so everything would need to ultimately
go through those two descriptors, which would disallow having the
"parallel" processing implied by the above diagram.

I don't see how this could be happening. The current octave in sid

It isn't the WM that's the problem - I'm still using GNOME.  I might

People with more shell magic than me might be able to simplify that to not use 
fifos, but I figured they were fair game since you get stream labels.  (That's 
basically all a fifo is.)

Technically speaking, that's all one command, per the Single UNIX Specifation.  
It matches the shell grammar start symbol "complete_command" documented 
.

So, basically, we have different basic building blocks (I don't know a grep 
variant that acts like LOCATE, for example), but the larger structure is very 
similar.

Most UNIX/Linux utilities for the command line assume all input on fd 0, all 
normal output on fd 1, and end-user notifications written to fd 2.  However, 
there's nothing actively preventing binaries from reading from fd 2, writing 
to fd 0, or expecting i/o on fds 3 through 9.  (IIRC, anything greater than 9

I can attest to that.  I also use a webmail client provided
by my mail service provider that does not allow the user
to manually set the "In-Reply-To" field.  The webmail client
generates one if you click on the Reply button within the
mailer itself.  But you have to receive the e-mail to reply
to it.  Here's how I do it.

(1) I subscribe to the list.  That way, I get *all* the
e-mails.

(2) An incoming e-mail from the listserv shows the "From"
field as the original sender's e-mail address, not the
listserv's e-mail address.  I'm not sure why, but it does.
The "To" field shows the list it was sent to, usually
debian-u...@lists.debian.org.  I select the "To" field,
debian-user@lists.debian.org, with the mouse and click
Edit -> Copy in the browser action bar.  I then click
on the "Reply" field.  I am now in another window in
which I can compose a reply.  The mailer, behind the scenes,
has set the "In-Reply-To" field based on the incoming message,
and the "To" field is pre-filled in with the sender's e-mail
address, which is not the e-mail address I want to reply to.
I then highlight the "To" field with the mouse and click on
Edit -> Paste in the browser action bar.  The "To" field now
contains the list address.  It's kind-of kludgy, but it works.

In Peter's case, his primary system was down and he was 
using a back-up e-mail address to post.  This e-mail address
was not subscribed to the list.  He couldn't "Reply" to
an e-mail he did not receive, he could only compose a new
one.  And the web-based e-mail client didn't give him a
mechanism to manually set the "In-Reply-To" header.

In a case like that, Peter, the best you can do is to make
your subject line match *exactly*, character by character,
with the mail you are "replying" to.  It will generally show
up in the archives next to the main thread under the title
"Possible follow-ups".  But it will be disconnected from the
main thread.  There's really nothing you can do about that.

These are all helpful tips and tricks, and I'll keep them
in mind.  I really won't know if I can do the kind of things
I want with these until I try, I suppose.  I don't have a
specific application in mind right now.  Let me give you a
simple example of a CMS pipeline for illustrative purposes,
so that you will get some idea of what I'm talking about.

This is a REXX EXEC (i.e. a script written in the REXX
interpretive language) designed to run on the CMS operating
system running in a virtual machine under z/VM:

--

'PIPE (ENDCHAR ?)',/* Declare pipeline endchar. */
   '  < USER DIRECT|', /* Read directory file.  */
   '  NFIND *|',   /* Discard comments. */
   'LOCM: LOCATE /MDISK/|',/* Select MDISK records  */
   'FIN:  FANINANY|',  /* Collect MDISKs and LINKs. */
   '  > OUTPUT FILE A',/* Write them to a file. */
   '?',/* End of stream.*/
   'LOCM: |',  /* Non-MDISK cards to here   */
   '  LOCATE /LINK/|', /* Select LINK cards.*/
   'FIN:'  /* Send them to faninany.*/
   /* End of stream and pipe*/
 
--

This is all one command, as viewed by the REXX interpreter.
The stuff between /* and */ are comments.  They are ignored
by the interpreter.  Note that all lines end in a comma,
which is the continuation character, except the last.  The
vertical bar, as with shell pipelines, is the stage separator.
The apostrophes serve as quote characters, just as in the shell.
PIPE is the name of the command to invoke.  The rest of the
stuff is just arguments to the PIPE command.  In other words,
the REXX interpreter itself has no concept of a pipeline.
It is just passing a string of characters to a CMS command
called PIPE.  It is the PIPE command that understands what
a pipeline is.  The question mark is defined as an
end-of-stream character.  It marks the end of a section of
pipe, if you will.

The pipe consists of a number of stages.  The stage numbers
and their names are as follows:

   1. <
   2. NFIND
   3. LOCATE
   4. FANINANY
   5. >
   6. LOCATE

Don't be confused by "<" and ">".  They are not redirection
operators.  There's no such thing as a redirection operator
in REXX or in CMS Pipelines.  "<" and ">" are the names of
stages, just like the others.  Stage 2 and stage 6 are two
different instances of the LOCATE stage.  They have separate
inputs and outputs.  LOCM and FIN are labels.  They are
names given to some of the stages so that they can be
referenced later.  You can tell they are labels because they
end with a colon.

Stage 1, "<", reads records (lines) from a file, the name
of which is USER DIRECT *.  (The asterisk, meaning "on the
first accessed disk you can find it on" is implied by default.)
Input stream 1 is unconnected
and not used, since it is the first stage.  Records from
the file are written to output stream 1.

Stage 2, NFIND, has its input stream 1 connected to output stream
1 of stage 1.  Records which do not begin with an asterisk
in column 1 are written to output stream 1.  Records which
do begin with an asterisk are written to output stream 2,
if it is connected.  Otherwise, they are discarded.
Since output stream 2 is not connected, they are discarded.

Stage 3, LOCATE, has its input stream 1 connected to output
stream 1 of s

Trial and error is an effective way to figure it out. [1] Depending on a
few factors though, it may be more instructive long-term to read the
source. I've recently been putting that philosophy to use in various
things where the documentation's not quite clear. Both methods have
their merits.

[1] possibly redirect std{out,err} to separate temp files and view them?

It looks crystal clear to me: blame your ISP routing tables, any proxy or 
service that it can be being used by them to filter Internet traffic or 
just its DNS servers :-)


It's a British-audience website and my ISP is British Telecom, plus it's an 
intermittent problem, so it's unlikely to be something like ISP routing tables, 
which shouldn't change on an hour by hour basis.


I guess it's just not a debian problem at all. Thought it might have been 
something in the way I set up my gateway server.


OK, I'll see if I can figure out a way of automatically inserting the nameserver 
4.2.2.1 into my resolv.conf via the dhcp config.


Thanks anyway, and Florian thanks for the tip re: 4.2.2.1

Maybe, who knows... but I think EDNS will interfere with many other

OTOH, what the OP is experiencing I also have suffered from time to time. 
Just changing the gateway to go out with another router (or switching

If you system provides stdlog (or a C++ equivalent), it is likely still file

The logcheck cron job explicitly mails the logcheck user.  I have an alias 
"logcheck: bss".

The apt cron job only generates output when there are issues.  It runs as 
root.  I have an alias "root: bss".

My daily job to check for upgradable packages runs as my user.  It only 
generates output when there are packages that could be upgraded.

In my home directory on each server, I have a .forward file with the contents 
"b...@iguanasuicide.net".

Each server knows how to send mail via (E)SMTP, although most either do not 
listen on any interface besides lo OR that port firewalled (most ports are 
firewalled).

So, I the results of all the cron jobs I care about delivered to my primary 
private email address.  Once there, some get filtered by my sieve scripts.  
Logcheck has its own folder, for example.

Re: one website gives "address not found" from LAN

[Adam Hardy]

Reposting with the issue recapped:

I cannot surf this particular public website from my LAN. Is it my DNS or my 
what, I don't know.


75% of the time with my normal setup I get "address not found" when surfing it.

This is some diagnostics I was doing:

a...@isengard:~$ host www.trade2win.com
Host www.trade2win.com not found: 3(NXDOMAIN)

And then with another nameserver:

a...@isengard:~$ host www.trade2win.com 4.2.2.1
Using domain server:
Name: 4.2.2.1
Address: 4.2.2.1#53
Aliases:

www.trade2win.com is an alias for panna-229.trade2win.com.
panna-229.trade2win.com has address 208.43.120.229
Host panna-229.trade2win.com not found: 3(NXDOMAIN)
Host panna-229.trade2win.com not found: 3(NXDOMAIN)


I can surf the site from a proxy website like proxify.co.uk

The intermittent nature of the problem is puzzling me too. Can anyone say what 
my course of action should be?

Use $() like you do with the date command. You have to redirect stderr 
back to stdout, which means running it in a subshell:



FILES=$( ( tar -zcvf - *  --exclude-from $EXCLUDES  | openssl des3 -salt

It may cause unexpected results if there're spaces in the filenames though.

Nvidia issues SOLVED by disabling gdm

[Patrick Wiseman]

Hello, all:

After much head bashing, I decided to try starting X using 'startx',
bypassing gdm.  My nvidia card is now working splendidly with the
195.36.03 beta driver, which I installed using the nvidia installer
(as that seems to be the easiest way to ensure I have 32-bit
compatible OpenGL libraries, which Google Earth requires).  Maybe I
should file a bug against gdm for apparent (although not invariable)
incompatibility with nvidia drivers?

I'll be the first person to admit that I know nothing about the UDF
filesystem.  To me, UDF means "United Dairy Farmers"  :-)
But in my experience, NEVER build a file system on an entire disk.
Always create a partition on the disk, then build a file system on
the partition.  I suspect that that is your problem.  Unfortunately,
that will not be of much help to you at this point.  But it may prevent
you from making that mistake in the future.

In

or 
http://lists.debian.org/debian-user/2010/02/author2.html
or 
http://lists.debian.org/debian-user/2010/02/author3.html
depending on when the reader opens the page,
are messages from peasthope and messages from 
Peter Easthope.  The messages from Peter Easthope 
were sent by the Shaw Web based mailer.

When a message was created by clicking the Reply button 
in that mailer, a correct In-reply-to parameter was included.  
No complaint.

The problematic case is where a message in the archive is 
read with the browser and then a reply is created by a 
click on the Compose button in the Web based mailer.  
In that case I can see the Message-id being replied to 
but the mailer offers no way to insert it for the In-reply-to 
parameter.  An example is this message.
"http://lists.debian.org/debian-user/2010/02/msg00283.html";
So for most of my messages, In-reply-to was correct.
At least one was faulty.

For comparison, if a reply is created with the NO mailer 
any of the SMTP parameters can be inserted manually.  
An old message can be read in the archive and a correctly 
threaded reply can be created.

I used the mailing list for at least a year before understanding
how this works.

I would avoid trying to store the file listing in any type of variable,
since you have no idea how big the list will be.

And, as others have noted, in the above case the file names list is sent
to stderr, so it doesn't mess up the stdout you requested for the
archive data.

I'd recommend using a "named pipe", or FIFO, like this:

  mknod filenames p
  tar -zcvf - *  --exclude-from $EXCLUDES 2>filenames  |
  openssl ... | dd ... &

NOTE:  the '2>filenames' and the ampersand to put the command into the
background.

Then, later in the script, you would do something like this:

while read filename
do
  # other work
done < filenames

I've not done the above with anything large enough to know, but the way
a FIFO works, the read loop will block, waiting for input, if it
exhausts the FIFO content.  The FIFO will generate a zero length read
after the last line from tar is captured which will terminate the loop.

As I'm not familiar with CMS, I have no idea if the following matches or
is completely off target ...

The default pipeline in shells always operates with stdout/stdin, which
is a bit limiting.

But, you can work around it, a bit, like this:

  cat abc_does_not_exist 2>&1 | wc

The 'cat' error message gets sent to wc.  The normal cat output is still
to stdout, so it also would be processed by wc, when the file exists.

The shell also allows you to open your own descriptors to files, using:

  exec 5>abc
  date >&5
  cat abc
  Fri Feb  5 09:15:15 PST 2010

Or, you can set the descriptor to point to another one:

  exec 5>&1
  date >&5
  Fri Feb  5 09:15:15 PST 2010

You can also create "named pipes" using 'mknod a_name p'.  For example:

  mknod fifo1 p
  mknod fifo2 p
  tr '[A-Z]' '[a-z]' < fifo1 >fifo2 &
  [1] 25269
  echo ABCDEFG > fifo1
  cat fifo2
  abcdefg
  [1]+  Donetr '[A-Z]' '[a-z]' fifo2

Perhaps one or another of the above will do what you want?

Upgrade freeradius etch to lenny.

[Account for Debian group mail]

Hello,

On one of our radius servers we upgraded from etch to lenny which means 
the freeradius server software was upgraded from version 1.1.3 to 2.0.4. 
This is a big upgrade for FreeRadius.


I've managed to get most of the freeradius server working properly except 
the accounting part. I see in the "radius.conf" file that the accounting 
is turned on and the accounting directory is still the same one used in 
the version 1 software. But still the accounting is not logging the 
information as it should, and I see no errors about it.


Anyone know what I have to do to get the accounting working?


Thanks,

Ken

Yes.  I'd missed Alternative number 1 and followed 2 
approximately.  I used the ncurses interface whereas

The extant system has 2.6.30 and 2.6.32 in /boot.  The 
"daily built" Squeeze installer worked with no snags.

Understood.

Yes.

OK, the installation default is "delay=0" but even 
with non-zero delay I couldn't get the Lilo prompt.
Finally I changed "install=bmp" to "install=menu" 
and booted single with no problem.

That's it!  Thanks.

The system is on its feet again.

UDF filesystem in removable harddisk crashed

[User]

  Hi, all kind friends. Help me! Sorry for my poor English.

  My OS is Debian Lenny for i386, and last month I bought a "Seagate
FreeAgent Desk" 1TB removable harddisk. In order to can be used on both
Linux and Windows, I chose UDF filesystem for it. The command of making
filesystem at that time was:

# mkudffs  -r 0x0150 --media-type=hd --utf8  /dev/sdb

  Note: I made UDF filesystem in the whole disk, not partition.


  It worked normally, read and wrote file normally. Today, when I mounted
it, and copied some files to it, found that it became very slowly. So I
unmounted it and tried to mount it again. But it could not be mounted
again!!! The filesystem was crashed!

  I have searched Google, found much software to recover data for UDF
filesystem, but they all work only for UDF CD/DVD, not for UDF harddisk!

  Oh, many valuable files are saved in the disk. Can anybody tell me some
way to save data in the disk? Thank you very very very much.

This is off topic from the OP's question, but one of the things that I
miss in the Linux environment that I used to use a lot in the CMS
environment is CMS Pipelines.  The shell supports pipelines, but they
are *single-stream* pipelines.  CMS pipelines supports *multi-stream*
pipelines.  That one feature alone makes CMS Pipelines so much more
powerful than shell pipelines.  I wish the shell supported multi-stream
pipelines.

A comment towards 'how would I know':

Traditional Unix and traditional C both made provision for stdin,
stdout, and stderr. When Stroustrup, et al., started working on C++
and its earlier predicessors, someone recognized the need for a fourth
stdXXX, namely stdlog.  I think it was/is a good idea, but it has
never gained enough traction to justify all the changes that would be
required if it were introduced into the POSIX standard. Instead, the
community has kept the name stderr, but changed the usage to something
that might better be named stdmsg, indicating both errors and action
logging. Its the sort of historical development that doesn't get recorded
in any man page (or at least any man page that newbies know about).

I was working on this a few weeks ago and AFAICK I needed the

terminal_input serial
terminal_output serial

According to the following bug report (which is also where I saw an
example using the two above lines in grub.cfg), concurrent output is
coming:

That does make sense, now that I think about it.  I didn't look
closely enough.  I saw what I expected to see.  The extracted
files themselves "always" go to disk.  But they don't in this

One thing I forgot to mention is that the symlink method used by the 
kernel install scripts in conjunction with boot loaders that use them,
such as lilo (for the i386 architecture) and zipl (for the s390
architecture) only allows the two most recently installed kernels
to be bootable.  Let's say that you install a 2.6.33 kernel in the
future.  That means that "Linux" in your lilo boot menu will boot
the 2.6.33 kernel and "LinuxOLD" in your lilo boot menu will boot
the 2.6.32 kernel.  The 2.6.30 kernel, though still installed, is no
longer bootable.  If you want it to remain bootable, you will need
to set "do_symlinks=no" and "do_bootloader=no" in /etc/kernel-img.conf
and maintain your /etc/lilo.conf file and your symlinks by hand.
Then manually run lilo to update the boot menu.

Assuming that you are content with only being able to boot the
two most recently installed kernels, you should manually purge
old kernels as they roll off the boot menu, in order to save space.
For example, after installing the 2.6.33 kernel, you would issue

   aptitude purge linux-image-2.6.30-2-686

to deinstall the old kernel, since it is no longer bootable.

Of course, an upgrade to an existing kernel (same package name,
different version number) replaces the current kernel.  It does
not install a new kernel.  Therefore, you would not purge the
old kernel under these conditions.

Do you have any shared storage that you're using which supports snapshots?
If you do, then a combination of coalescing the running VM's to disk and
taking a snap and also using traditional backup methods (application aware)
to disk/tape for archival and complete failure of the storage is a
reasonable thing to do.

I'm running testing, and your work-around to download doesn't work

For xls files I get

I'd say you don't have to care about the order (intall driver <-> device

Before I got fglrx configured for 3D support, GoogleEarth just popped up a
warning that it would run slowly and haltingly, complete with instructions,
and it did.  It didn't crash.

Once fglrx was installed correctly, it ran great.

Then support for my Radeon Mobility FireGL 9000 was dropped and the 2.6.30
kernel came along. fglrx upgrades eventually stopped working in the 2.6.26
kernel and I changed to Firmware-Linux and moved to the 2.6.30 and the new
xserver-xorg.

That seemed fine and, strangely, to improve over time. It went from
flickering but not quite halting to running very smoothly in the course of
about 4 sessions.  A few days later GoogleEarth and xscreensaver started
seg-faulting severely.  They took out big sections of my file system on
*two* computers.

I've never had crashes like that in 7 years of Debian. I've got one drive
completely down and unbootable.

I haven't found much evidence of what happened. None of the upgraded
packages in that period seem X related.  I've just been living in CLI land
until I get time to repair and investigate more.

I'm scripting a backup solution, the line that does the business looks

Because of the "v" flag tar writes to stdout the name of each file
copied. How can I get that output redirected to a variable, to use
later in the script?



You probably want to put the data into an array rather than a
variable.  An explanation of how to do so can be found here:
 http://tldp.org/LDP/abs/html/arrays.html

Scroll down to the end of Example 26-7 (just about Example 26-8).
Basically, direct stdout to a file, then cat the file to add it to an
array.


The array=( element1 element2 ... elementN )  initialization
operation, with the help of command substitution, makes it possible to
load the contents of a text file into an array.

#!/bin/bash

filename=sample_file

#cat sample_file
#
#1 a b c
#2 d e fg


declare -a array1

array1=( `cat "$filename"`)#  Loads contents
# List file to stdout  #+ of $filename into array1.
#
#  array1=( `cat "$filename" | tr '\n' ' '`)
#change linefeeds in file to spaces.
#  Not necessary because Bash does word splitting,
#+ changing linefeeds to spaces.

echo ${arra...@]}# List the array.
#  1 a b c 2 d e fg
#
#  Each whitespace-separated "word" in the file
#+ has been assigned to an element of the array.

element_count=${#array1[*]}
echo $element_count  # 8



  

Why not simply use the  t option for content listing :

tar tvf  * --exclude-from $EXCLUDES

That's true: programs using stdout for data output certainly have to
use stderr as a way to report any additional info.
