#207250 — From installation DVD to original ISO file.

I have BW limits such that I cannot download requires iso files.
Therefor I have purchased a complete set of installation DVDs.
I require that the MD5SUMS (etc) of the generated file match the original.

I went thru this a few years ago so I know care must be taken to exactly 
match the file size.

The solutions I was given at the time revolved around using "isoinfo".
[E.G.     > # COUNT=$(isoinfo -d -i /dev/cdrom)
     > # dd if=/dev/dvd bs=2048 status=progress count=$COUNT 
conv=notrunc,noerror > disc.iso
]

I've gone in circles trying to find a package including it in *current* 
Debian repository.

Is it available? If so where?
Is there a recommended alternative procedure?

TIA

Isn't it in "genisoimage" ?

  https://packages.debian.org/stretch/amd64/genisoimage/filelist
has
  /usr/bin/isoinfo

  COUNT=$(expr $(/sbin/isosize /dev/cdrom) / 2048)

from package "util-linux".


Have a nice day :)

My search methodology was faulty.
I hadn't thought of searching packages.debian.org for an included file.
Doing it that way also yields
    https://packages.debian.org/stretch/libcdio-utils
with interesting links at
    https://www.gnu.org/software/libcdio/projects.html

On the man page
      https://manpages.debian.org/stretch/util-linux/isosize.8.en.html
I had seen:

I wasn't sure if that meant it was not suitable for my purpose.


Thanks

Note the different names "isoinfo" <-> "iso-info".
These programs take different options and put out different text formats.
"iso-info" does not tell the size.

Your command
  COUNT=$(isoinfo -d -i /dev/cdrom)
looks questionable, though.

A program run here prints multiple lines of which the right one needs to
be picked and stripped of its prefix text:

  COUNT=$(isoinfo -d -i /dev/cdrom | grep 'Volume size is: ' | sed -e 's/Volume size is: //')

This paragraph is just an explanation why "isosize" is of use and
why its result can differ from the image file size or the readable
size of the medium.

(The last sentence is quite wrong. Run-out blocks are not readable. They can
 only cause the Linux TAO CD read-ahead error if the drive invites for it.
 Most optical media types pad up a burn session to the next multiple of
 16 or 32 blocks. Some types are random access media and offer their full
 capacity for reading rather than the size of the recently written ISO.
 Only CD-R[W] with write type SAO and DVD-R[W] with write type DAO reliably
 restrict the readable size to the written size.
)


Have a nice day :)

Hm. There seem to be several 'isoinfo' (I'm assuming that isoinfo is
what your 'it' refers to):

  tomas@trotzki:~$ apt-file search isoinfo
  engrampa: /usr/lib/engrampa/engrampa/isoinfo.sh
  file-roller: /usr/lib/x86_64-linux-gnu/file-roller/isoinfo.sh
  genisoimage: /usr/bin/isoinfo
  genisoimage: /usr/share/man/man1/isoinfo.1.gz
  libguestfs-gobject-dev: /usr/include/guestfs-gobject/struct-isoinfo.h
  manpages-ja: /usr/share/man/ja/man8/isoinfo.8.gz
  manpages-pl: /usr/share/man/pl/man1/isoinfo.1.gz
  patool: /usr/lib/python2.7/dist-packages/patoolib/programs/isoinfo.py
  patool: /usr/lib/python3/dist-packages/patoolib/programs/isoinfo.py

I guess you're looking for the one in package 'genisoimage'. But my
crystal ball is somewhat cloudy...

I hadn't thought of using "apt-file search ***".

Go here:
https://www.debian.org/distrib/packages

Under the heading "Search the contents of packages", choose
Display = packages that contain files named like this
Distribution = stable
Architecture = any
Type your search Keyword: isoinfo
Click on Search button.

Read this result page:
https://packages.debian.org/search?searchon=contents&keywords=isoinfo&mode=exactfilename&suite=stable&arch=any

This answer assumes I've correctly understood the ambiguity in your
question. (ie guessing what "it" actually refers to?)
If not, please improve the question.
