"wine" command is a 32-bit ELF binary and "wine64" command is a 64-bit 
ELF binary.
In my experience it doesn't matter which one to use, as long as you run 
programs inside a prefix that supports both 32-bit and 64-bit (WoW64). [1]


You can use just one prefix for both 32-bit and 64-bit programs, or you 
can have as many prefixes as you want, each could be setup with 
different settings and\or DLLs, tailored specifically for some program.

It is up to you how to manage them all.
I use "q4wine" program (it could be installed from Debian repo) that 
helps to make some things easier.
There is also commercial software "CrossOver" [2] from the authors of 
WINE project, but I've never used it.

I take it that by "rtl files" you mean RealTek firmware blobs for
RealTek devices.

What I found was that Bullseye (Debian 11) wants the firmware .deb
package, not the extracted firmware files. This may or may not work on
Buster (Debian 10). Also it wants the file in the root directory of the
USB device.

You may be able to install without them if you don't need the interface
they support to install. You would need some other interface either
during installation, or shortly after installation to bring the
firmware package in.

Probably the easiest option: you might try the unofficial with-firmware
installation images. Depending on your requirements, you should be able
to drill down from this page:

UEFI itself, on the other hand - definitely can not, unless you resort

Minisforum X35G hangs on first boot.

[R. Ramesh]

Hi,

  I am trying to install debian buster 
(debian-10.8.0-amd64-netinst.iso) on minisforum X35G. This comes 
installed with windows 10. It has  Core i3-1005G1 cpu 16GB memory and 
512 PCIe nvme SSD as far as I can tell.
Everything during the install goes fine (warnings about some realtec NIC 
firmware, but network is fine for install). However on the first reboot, 
it gets all the way where it complains about NIC firmware and hangs 
right there. The only thing I can do is to press power button and the 
kernel will get out of hang and shutdown and power off. Windows seem to 
dual boot fine.


  I do not know how to proceed further with debug. Any help is much 
appreciated.


Regards
Ramesh

"Zapped" exactly how? GPT tables are on both ends of the disks. Wiping the first

As long as you get sshd running in your WSL debian, you will be able to
ssh fine.  X forwarding should also work, but I've never tried it
myself.

You'll need a Windows X server installed.  vcxsrv is open source and

A web search will find instructions for configuring WSL daemons to

No idea how to do this.  The debian install will go to a directory in
your %LocalAppData%; I guess you could mount a separate disk to that
path, but I've not tried this.

If you set up sshd in your WSL debian, you will end up with a shell in
the debian environment.  You can navigate to the Windows filesystem if
you need to.  You could also setup an ssh server on Windows if you like.
I hear OpenSSH server is available as a feature to enable in Windows.

Installing Debian from a hard disk with Windows to a USB stick

[Cmdte Alpha Tigre Z]

Hi.

I'm trying to install Debian 10.8 on a USB stick, and it is not Debian Live,
from a hard disk that has Windows 7 installed.  Since I don't have
any CD or DVD, and I need the USB stick to install Debian on it,
I can't use the USB stick to put the ISO image on it.

I have downloaded the first ISO DVD image, hd-media/vmlinuz and
hd-media/initrd.gz.  As I understand, the standalone win32-loader
downloads its own Debian image, so I supposed I needed the setup.exe
from the ISO image.  I put debian-10.8.0-i386-DVD-1.iso, g2ldr, g2ldr.mbr
(these two from the ISO), initrd.gz, setup.exe, vmlinuz and win32-loader.ini
on the root of C:

I modified win32-loader.ini from:
[installer]
kernel=linux
arch=i386
i386/linux=install.386/vmlinuz
i386/initrd=install.386/initrd.gz
i386/gtk/linux=install.386/vmlinuz
i386/gtk/initrd=install.386/gtk/initrd.gz

[grub]
g2ldr=g2ldr
g2ldr.mbr=g2ldr.mbr

to:
[installer]
kernel=linux
arch=i386
i386/linux=vmlinuz
i386/initrd=initrd.gz

[grub]
g2ldr=g2ldr
g2ldr.mbr=g2ldr.mbr

The problem is that I don't know if modifying win32-loader.ini that way
I can make debian-installer boot from the files on C: instead from a CD or
a DVD or an USB stick; nor I know if GRUB2 will load successfully itself
and linux and the RAM disk.

Please, could you help me?

Thanks in advance.

RTL problem

[Maureen L Thomas]

I have a Lenovo ideacenter 510A-15ABR, Amd A12-9800 that went crazy.  
The cmos was frozen from too many attempts to get into it so I had to 
open it up and play the jumper game to reset it.  This went off without 
a hitch.  Once back together it would only boot to fsckd-cancel-msg:  
Press CTRL+C to cancel filesystem checks in progress.  The CTRL+C did 
not stopit and it ran forever.  So I decided to re-install debian 10.  
While doing so I get to the part about the entering the needed rtl files 
which I have on DVD and on USB.  I tried both but neither of them would 
work.  I cannot get it to even come up to a command line to do dmesg and 
see what the real problem may be.  Can anyone help?

Not sure about that command above (no means to try it just now), but _with_  
PulseAudio, I can record the sound that is being played back just fine by  
means of "monitor" audio devices. E.g. I have the following command to  
record my screen (`0:v`), the "monitor" device (`1:a`) and a microphone  
(`2:a`):


exec ffmpeg -video_size 1600x1200 -framerate 12 -f x11grab -i :0.0+0,0 -f pulse -ac 2 -i 
0 -f pulse -i 1 -c:v libvpx-vp9 -deadline realtime -b:v 2M -c:a libvorbis -map 0:v -map 
1:a -map 2:a "recording.webm"

adapted from these two sources:

-> https://trac.ffmpeg.org/wiki/Capture/Desktop
-> 
https://askubuntu.com/questions/682144/capturing-only-desktop-audio-with-ffmpeg

It may of course be true that the hardware _does_ support/accellerate this  
monitoring capability, but it does not seem to be entirely uncommon a  
feature? Here, it even works inside virtual machines :)


Btw. the existence of monitor devices can be checked in `pavucontrol` where  
under "Output" it lists two monitor devices here: One for the HDMI output  
and one for the "Built-in Analog Stereo" Output.



AFAICT, this recording facility is getting harder to find on most
computers, if you're not prepared to fork out for a sound card.
I've been fortunate, in that just as my ancient Pentium III expired,
I have acquired a Dell Precision T3500 which has a well endowed
(integrated) sound card.

I'm still finding my way round it: for example, it also has HDMI
playback, but I haven't yet worked out how to exploit it. The machine
has one DVI output and two DisplayPorts, so I need to find a
DisplayPort/HDMI adapter to see if that would yield anything.


[...]

As far as I can tell, DisplayPort can transport audio without the need for  
an HDMI adapter. Here, a Radeon Pro W5500 graphics card is connected to a  
Dell U2713HM display which has one HDMI, DP, VGA and DVI input each. The  
W5500 is connected to the DisplayPort and if I play sound to the "HDMI"  
output, the display outputs that sound through its headphones socket.


Similar to your case, there are no HDMI ports on the graphics card.
In my case, it is only DisplayPorts.

Thank you, Mr. Kenneth Parker.

I noticed in the "syslog" that modprobe couldn't find the module "rtw_8723de"
that was not listed on the "hardware-summary"; instead, lsmod shows
"rtw88_8723de".
Then, the module "r8169" tried to load the firmware but that module
belongs to the
GbE card.

I think I'll be sending this to the bug report.

Have a nice day.

On no machine, unless specifically configured, which is not trivial at
all.

It would be helpful if people around here learned to read carefully the
questions before trying to answer them. If they did, they would have
noticed that the question was not to record the ambient sound but the
sound BEING PLAYED. To achieve it requires either a hardware connection
between the output and the input of the sound controller or the
collaboration of the sound driver.

The FFmpeg wiki has some very useful information on concatenating media
files where a simple 'cat' won't work - I use its 'concat demuxer'
regularly to contatenate MP4 files (Android starts a new video file when
a 4GB limit is hit):

Yes, I know concatenation is supposed to be a feature, but they messed
it up.

You may not know, but the expert consensus is that, although the codec
Vorbis was excellent, and Opus even better, the design of the format Ogg
was terrible. The non-working concatenation is not the worse part. The
worse part is probably that supporting any new codec in Ogg requires
code, and non-trivial code even. Look at this:

http://git.videolan.org/gitweb.cgi/ffmpeg.git/?p=ffmpeg.git;a=blob;f=libavformat/oggparseopus.c

Compare to what it takes to support the same codec in Matroska:

http://git.videolan.org/gitweb.cgi/ffmpeg.git/?p=ffmpeg.git;a=commit;h=30549294ef0f796d48b1ffa482bd9315d4dbb83c

If concatenation really did work, it would work with all players,
because they would not even be able to detect it happened.

But it is worse than that, it is not weird players not handling the
format correctly that do not work. Concatenation works with players that
play it fast and loose with the format and fails with players that
support it completely, because they take the serial id of the streams
into account.

I also have an Acer minilaptop.  It also has a WiFi on/off hotkey (Fn+F3).
The led that belongs to the WiFi state is the fourth.
The difference here is that it works from startup.  If the WiFi
is disabled through this hotkey, Windows has no way to reenable it,
though it knows that the WiFi is disabled this way.

I was told *by the developer* (Monty, in #vorbis IRC long ago) that
Ogg Vorbis files were designed for this.

A few Google searches to provide supporting evidence:

https://linux.die.net/man/1/oggz-merge

  If you want to create a file containing some Ogg files sequenced one after
  another, then you should simply concatenate them together using cat. In Ogg
  this is called "chaining". If you cat Ogg Vorbis I audio files together, then
  the result will also be a compliant Ogg Vorbis file.

https://hydrogenaud.io/index.php?topic=114262.0

  Chaining in an ogg container is as simple as it gets. Just concatenate two
  separate ogg files together, the result is a chained file.


However, I will note that there *are* players that don't handle
chained Ogg Vorbis files properly.  So, make sure you test with the
actual player you intend to use.

 A good thought, thank you. A careful inspection of the computer and
 search of the Hardware Maintenance Manual reveal no such physical
 switch. There is a function key switch which relies on OS support to
 actually do anything, and I doubt that is active in d-i.

It's the other way around. Pure MP3 files are just a concatenation of
self-delimited packets, concatenation will just work.

MP3 files will usually have ID3 and/or XING packets for metadata at the
beginning or the end, concatenation will include them, and the metadata
will be invalid, but it will not prevent the file from being played.

On the other hand, Ogg files are NOT concatenable, even those that
contain only Vorbis audio. Some player will ignore the discontinuity at
the concatenation points, but not all.

Also, let it be said that: decoding playing, recording and encoding
audio files to concatenate them is a terrible idea, because it will lose

I have "deb https://dl.winehq.org/wine-builds/debian/ buster main" in

The Debian wine wiki says "Users on a 64-bit system should make sure 
that both wine32 and wine64 (or wine32-development and 
wine64-development) are installed".


I have "deb https://dl.winehq.org/wine-builds/debian/ buster main" in 
sources.lists. I installed "wine64". The package lists before and 
after are below. When I try to install a 64bit program using "wine 
64bitprogram.exe", I get the message:


"This program can only be installed on versions of Windows designed 
for the following processor architectures: x64".


So then I ran "wine64 64bitprogram.exe" and I get the message:

"wine: '/home/myacct/.wine' is a 32-bit installation, it cannot 
support 64-bit applications."


Installing wine64 didn't create a .wine64 directory. It seems like I'm 
close, but what am I missing? Something to do with WINEPREFIX?
You have to create a fresh prefix, since you have been using only 32-bit 
one.
It could be done by moving or renaming (for backup) existing one ".wine" 
and running:

    $ wine --init
This command will create a default "$HOME/.wine" prefix that will run 
both 32-bit and 64-bit applications.

Hmm, with vim something like 'vimdiff $current $new' should work, there 
is no need to echo the variables firsts, and I would be surprised if 
emacs couldn't do something similar.

That would have to be implemented in dpkg and ucf.

Recently more and more packages have been adding support for 
conf.d-style directories. That way you can keep your local 
customizations completely separate from the default configuration and 
there is no prompt from dpkg or ucf.

Richard,

You still have he magic Mifi hotspot from T-Mobile that you were connecting
to via USB. That may well have DHCP and DNS functionality built in - assuming
you have wifi drivers installed on your two machines, it may well "just work"
in assigning addresses, allwoing for communication between machines.

That's what it's _designed_ for :-)

That way, you can check that both machines work - they have something to talk
to and you don't necessarily have to go back to TLDP references that may well
be out of date.

All best, as ever,

Andy C.

Problème de souris

[BERTRAND Joël]

Bonsoir à tous,

Je continue de me battre avec un Raspberry PI servant de client VNC.

Le système est en read-only. Le serveur VNC est un PC tournant sous
Windows 7 (tightvncserver). Sur le rPI tourne tightvncclient. J'ai eu
des problèmes de clavier, mais en désactivant la compression vnc et en
utilisant un encodage moins gourmant, le clavier est utilisable. Je
suppose que le réseau étant sur une interface USB, il y a avait un effet
de bord.

Néanmoins j'ai toujours un problème de souris. Et ce problème est
présent, vnc actif ou non (donc sans avoir de trafic réseau soutenu).

J'ai installé ce rPI avec une souris classique d'origine Lenovo.
L'interface était fluide. Arrivé chez le client, je constate que la
souris sans fil (Logitech) a une certaine latence, je mets ça sur le
compte des piles un peu faibles, je cherche une souris filaire et ça
fonctionne.

Arrive l'utilisateur final le lendemain. La souris sans fil provoque
toujours cette latence insupportable (elle bouge avec un retard d'une
bonne demi seconde). Il met donc à la place une souris filaire
(logitech) qui fonctionne partout ailleurs et cette souris ne fonctionne
pas sur le rPI. Les boutons sont reconnus, mais le pointeur de la souris
ne bouge pas. Rien d'aberrant dans les logs, aucune erreur.

J'avoue ne pas comprendre et je suis preneur de toute idée...

Bien cordialement,

JB

I have been using that device for a few days, seems to working mostly
fine.  Only tested it with Linux 5.10, though (the kernel in
bullseye/unstable).

Some observations/caveats:

- The firmware-realtek package is required.

- The r8188eu module for the dongle is in the staging area, as it does
  not quite meet the kernel developers' standards, a problem with
  various Realtek drivers.  In theory it might even be removed some day,
  but since it has been there for over seven years and the hardware is
  very popular this is highly unlikely to happen in practice.

- The activity LED on the dongle sometimes stays on during suspend and
  then remains in that state after resume until the device is
  re-plugged.  This may or may not bother you.

Considering the low price, I cannot really complain.

Yes, that was my very next sentence, which you snipped: "This should
allow a more focussed report from the installation logs (of which
we've seen nothing IIRC)."

But it appears that I might need to point out that it's very easy and
quick to re-collect a failing installation log at any time if the
"original" ones were lost/overwritten or whatever:

 1. Boot with the appropriate installation medium.

 2. Proceed with expert installation in the original manner,
as far as the "Detect Network Hardware", which of course fails.

 3. After the failure, and back at the Main Menu, select
"Save debug logs".

 4. Insert a USB stick, switch to VC2, mount the stick and create
a directory on it.

 5. Back at VC1, complete the directory name at the prompt and
save the logs. (ls on VC2 if you want to check them.)

 6. Select "Abort the installation". All that should have taken
about five or ten minutes so far.

 7. Read/edit/post excerpts from the logs at leisure. (That's when
it helps to know what strings you're looking for.)

That's what's lacking from the bug report.

The OP wrote "The Problem is Recreated. It's hard to figure out how
to describe something so early in the Install Process."

That's how you do it.

David.

Chuckle. I use a crossover cable to connect this computer¹ to the
wall socket. It's totally unnecessary to be crossover, but it's
yellow (originally to distinguish it from blue, straight-through
cables) and better fits in with the decor, I'm told.

The privacy issue is not what's running on either end, but the fact
that you're broadcasting everything to the neighbourhood.

I looked back and noticed that Brian had already made my suggestion of
a cheap router—back in August 2019. I think Dan's suggestion was the
best, though:

   "However, you have a history of trying to avoid the good
decisions that people steer you towards, so I encourage you to
give Bluetooth a miss entirely and go for an infrared LAN with a
ceiling reflector."

But sorry if this is all off-topic. Let's look back and see what
is on-topic:

One way is to run alsamixer in an xterm.
Help is in the top-right corner.

$ arecord -l   will give you a list of capture devices.

To record, you could type, for example, in another xterm:

$ arecord -d 10 -f cd -v -v -v -D plughw:0,0 /tmp/audiofile.wav

where 10 gives you ten seconds; 0 gives you infinite (^C to stop),
  cd gives higher quality (44100) than the default,
  dat would give you the more modern 48000,
  -v … gives a crude VU meter,
  0,0 is the bit you have to determine from   arecord -l
⮤ device
  ⮤ card (usually 0, but matters if you have, say, PCH and HDMI).

While arecord is running, you can play with the sliders for levels,
including monitoring with speakers/headphones, and changing the
capture device with .

Yes, I used to use aumix, but that's OSS (passé), not ALSA.

If you can't get ALSA to work, you might have to use pulseaudio instead.
I believe that can overcome a card's limitations through software.

plusieurs serveurs DNS, le deuxième serveur DNS n'est pas interrogé quand
le premier à répondu "nom de domaine inconnu".
À ce titre, il serait logique qu'un serveur unique sache répondre à tout
quitte à chercher ailleurs les réponses qu'il ne connaît pas.

En d'autres termes, je suis un peu perdu ...

Installed firmware-atheros, rebooted, but didn't help.

It appears that your instructions for the either of the two dongles
were interchanged. Understood. Intervened to rectify.

Installation didn't help.

My original request was different. I have already ordered for return
of the two usb dongles. But thank you ...

IF you're using pulseaudio as your sound server, there are some neat

If it’s about playing a file and recording its audio to mp3, the
following will work:

ffmpeg -i your-file.avi your-file.mp3

Change your-file.mp3 to your-file.wav if you prefer wav output. 
Works with any input format ffmpeg can play.

Well, you're running a kernel that's no longer on the stable mirrors,
because it has been superseded.  If you need the headers to match it, you
will need to pull them from a source that still has them (e.g. wherever
you got this kernel from).

If you no longer have such a source sitting around, consider using
snapshot.debian.org.  You can retrieve the single package that you
want by hand, or you can try to do fancy crap like using it as an apt
source.  The instructions are on the web page.

Ah -- twm. Fond memories. I upgraded to Fvwm :-)

Back on topic: I see you have a minimalistic setup. Perhaps
you need alsamixer/amixer to learn about your sources and
get the sound routing right.

Sorry, I'm a bit tight on time, otherwise I'd play a bit around
to see whether it works.

If you are playing something with mplayer, perhaps you don't need
a recording app at all -- (see mplayer's "-ao" option, for "audio
output". Something around

  mplayer ... -ao "mp3:file=foo.mp3"

might just work for you).

There is one other thing you have to take into account here:

To get the TCP/IP layer working, you'll have first to get the

roughly to a bunch of computers tied to one or more network

they don't "talk to each other".

So if you want to succeed in your two-box scenario, you'll have
to convince one of your two boxes to play the role of an "access

"hardware" plays along.

Well. I lied somewhat above. There is also "ad hoc" [2] mode,
which I have no experience with. Again, the network "hardware"
has to be willing.

I put network "hardware" in quotes, because your humble WiFi

Please install (if not already) gnome-sound-recorder and set up

convert the sound to mp3.

Command line? (from simple to complex) arecord, sox, ffmpeg 

GUI? I don't know. Perhaps snd, audacity (those are actually sound
editors, but you can /also/ do recording)

There are many, many programs in the Debian repository which can
record sound. Which one is good for you will depend a lot on your
needs and preferences.

If you have a desktop environment installed, there will be some kind
of "standard" sound handling app already there. For example, for
Gnome there is "Gnome sound recorder" (package gnome-sound-recorder).

You can get to the info strictly by mouse clicks for icons on the

It's not what I wanted. Up to now the only launchers I had created were

Sí para hacerlo funcionar.
El controlador que trae el cd para Linux es una porquería.
Vas a tener que bajar de gitHUB código específico y compilar el módulo.

Después de eso, va joya.

PD: Trata con MUCHO cariño el cable de conexión. Tanto el cable, que 
internamente tiene unos hilos del diámetro de un cabello, como los 
conectores, terminan trayendo problemas.

   learning by doing


Theory and practice are both important. It is crucial to understand how 
IP networks work, so I'd start with book like "TCP/IP Network 
Administration"


That book is not available at the local library but some chapters are on 
the internet. I'll spend some time with them.





During installation
server software was installed on *ONE* of them. Communication will be
via WiFi.


Clarification: Installation was done using only the contents of the 
first DVD of the installation set. They have never been connected to the 
internet.







Did they get IP addresses from the DHCP running on your wifi router or 
did you set IP addresses manually?


I have no router and the installer never prompted for an IP address.

From the rest of your post I suspect you are assuming some background I 
don't have.


In my original post I asked:

What internet search terms will lead to productive results?

A private reply suggested:
https://html.duckduckgo.com/html?q=home%20lan%20setup%20wireless

Though the resulting links are primarily Windows-centric, I think my 
most productive path will be to follow them with the goal of asking 
better questions.

  Part 1 (Answers last questions first).

  Google Linux WiFi Networking Overview
  Google Linux Wifi Networking Administration Overview

  if you want more general remove the word "WiFi"


  Part 2 (Asides to be ignored:  :) )

  for my own needs i just use a crossover cable and skip 
WiFi entirely - probably because in more ancient times 
i've done connections between machines via null modem 
serial port cables.

  i don't need WiFi here and i dislike broadcasting 
anything for no reason other than to avoid a cable run.

apt upgrade merging modified files

[Michael Grant]

When I apt-update, sometimes I update something for which I modified a config 
file and I get this menu:

Configuration file '/etc/matrix-synapse/homeserver.yaml'
 ==> Modified (by you or by a script) since installation.
 ==> Package distributor has shipped an updated version.
   What would you like to do about it ?  Your options are:
Y or I  : install the package maintainer's version
N or O  : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
 The default action is to keep your current version.
*** homeserver.yaml (Y/I/N/O/D/Z) [default=N]

Sometimes, rarely, I get a 5th option offering to try to merge the
files.  I don't know what causes the merge option to be available or
not.

If this is a file which I indeed modified, what I inevitably end up
doing is using the Z option, popping into a shell, then presents me 2
variables (without $ in front of them) which give me 2 files: current
and new.

So what I do is manually echo the two variables out (putting a $ in
front of them) and run emacs and emerge them together.  This is fine,
it's usually pretty easy.

Is there some way I can at minimum add a 5th option to the above menu
to run emacs in emerge mode with those files as args?  This would save
lazy me the steps of echoing the vars and starting emacs manually.

I run etckeeper, it would be really sweet if this was smart enough to
attempt a 3-way merge (merge with an ancestor file).

kernel sources for Debian 10.6 security update kernel 4.19.0-12-amd64

[Eerapu, Nipuna Sri]

Hi Team,

I am trying to download kernel sources for kernel 4.19.0-12-amd64 and getting 
below error.

As part of my project, I want to compile drivers for this kernel version.

root@linux-ndeb106:/usr/src# uname -r

Re: HS: petite question bash et variable en argument d'une commande

[Marc Chantreux]

salut,

> Comme indiqué de manière très détaillée sur 
> https://mywiki.wooledge.org/BashFAQ/050
(désolé c'est en anglais), stocker des commandes dans des variables est très 
hasardeux.

je ne lit plus jamais qu'en diagonale toute litterature spécifique à
bash mais oui: les choses sont compliquées voir impossibles dans une
chaine. par contre ...

> La façon la moins risquée est de passer par un tableau (d'ailleurs
> t'avais évoqué l'idée dans ton message initial).

non! déjà: le seul tableau que posix connaisse est $@ donc

date_args=( --date="1 days ago" )
date "${date_args[@]}" "+%A %d %B"

nécessite au moins mksh pour être lu. et si tu utilises plus gros: je te
conseille de passer tout de suite du coté de zsh mais rien ne justifie
de sortir un veau comme bash dans le cas présent.

ensuite: la façon la moins risquée s'appelle une fonction et c'est même
fait pour. ca permet de surcroit de profiter

  * de la localisation des variables dans le contexte de la fonction.
  * du paramétrage d'une valeur par défaut

exemple:

mydate () date -d"${1:--1day}" '+%A %d %B'
mydate
mydate tomorrow

me donne

mercredi 24 mars
vendredi 26 mars

autre manière de faire pour éviter le quoting hell: xargs
https://pubs.opengroup.org/onlinepubs/9699919799/utilities/xargs.html

date=tomorrow

# des trucs ...

<<. xargs -d'\n' date
-d ${date:--1day}
+%A %d %B
.

xargs prend aussi un fichier, du coup tu peux composer ta commande
petit à petit

exec 9>/tmp/mydate
>&9 echo "-d ${date:--1day}"
>&9 echo '+%A %d %B'
exec 9>&-
xargs -a /tmp/mydate -d'\n' date
