    Command:

    dpkg-deb

    
    
    

    SYNOPSIS

           dpkg-deb [option...] command
    
    
    

    DESCRIPTION

           dpkg-deb packs, unpacks and provides information about Debian archives.
    
           Use dpkg to install and remove packages from your system.
    
           You can also invoke dpkg-deb by calling dpkg with whatever options  you
           want  to  pass to dpkg-deb. dpkg will spot that you wanted dpkg-deb and
           run it for you.
    
    
    

    COMMANDS

           -b, --build directory [archive|directory]
                  Creates a debian archive from  the  filesystem  tree  stored  in
                  directory. directory must have a DEBIAN subdirectory, which con-
                  tains the control information files such  as  the  control  file
                  itself.  This  directory will not appear in the binary package's
                  filesystem archive, but instead the files in it will be  put  in
                  the binary package's control information area.
    
                  Unless  you specify --nocheck, dpkg-deb will read DEBIAN/control
                  and parse it. It will check it for syntax errors and other prob-
                  lems,  and  display  the name of the binary package being built.
                  dpkg-deb will also  check  the  permissions  of  the  maintainer
                  scripts  and other files found in the DEBIAN control information
                  directory.
    
                  If no archive is specified then dpkg-deb will write the  package
                  into the file directory.deb.
    
                  If the archive to be created already exists it will be overwrit-
                  ten.
    
                  If the second argument is a directory then dpkg-deb  will  write
                  to  the file package_version_arch.deb, or package_version.deb if
                  no Architecture field is present in the  package  control  file.
                  When  a  target  directory is specified, rather than a file, the
                  --nocheck option may not be used (since dpkg-deb needs  to  read
                  and  parse  the package control file to determine which filename
                  to use).
    
           -I, --info archive [control-file-name...]
                  Provides information about a binary package archive.
    
                  If no control-file-names are specified then it will print a sum-
                  mary of the contents of the package as well as its control file.
    
                  If any control-file-names are specified then dpkg-deb will print
                  them  in the order they were specified; if any of the components
                  weren't present it will print an error message to  stderr  about
                  each one and exit with status 2.
                  the order in which they appear in the control file. If more than
                  one control-file-field is specified then dpkg-deb  will  precede
                  each with its field name (and a colon and space).
    
                  No errors are reported for fields requested but not found.
    
           -c, --contents archive
                  Lists the contents of the filesystem tree archive portion of the
                  package archive. It is currently produced in the  format  gener-
                  ated by tar's verbose listing.
    
           -x, --extract archive directory
                  Extracts  the  filesystem  tree  from a package archive into the
                  specified directory.
    
                  Note that extracting a package to the root  directory  will  not
                  result  in a correct installation! Use dpkg to install packages.
    
                  directory (but not its parents) will be  created  if  necessary,
                  and  its permissions modified to match the contents of the pack-
                  age.
    
           -X, --vextract archive directory
                  Is like --extract (-x) with --verbose (-v) which prints a  list-
                  ing of the files extracted as it goes.
    
           -R, --raw-extract archive directory
                  Extracts the filesystem tree from a package archive into a spec-
                  ified directory, and the control information files into a DEBIAN
                  subdirectory of the specified directory.
    
                  The  target  directory  (but not its parents) will be created if
                  necessary.
    
           --fsys-tarfile archive
                  Extracts the filesystem tree data  from  a  binary  package  and
                  sends  it to standard output in tar format. Together with tar(1)
                  this can be used to extract a particular  file  from  a  package
                  archive.   The  input  archive  will always be processed sequen-
                  tially.
    
           -e, --control archive [directory]
                  Extracts the control information files from  a  package  archive
                  into the specified directory.
    
                  If  no  directory is specified then a subdirectory DEBIAN in the
                  current directory is used.
    
                  The target directory (but not its parents) will  be  created  if
                  necessary.
    
           -h, --help
                  matting options (including escape sequences and  field  tabbing)
                  can  be  found  in the explanation of the --showformat option in
                  dpkg-query(1).
    
                  The default for this field is "${Package}\t${Version}\n".
    
           -zcompress-level
                  Specify which compression level to use on the  compressor  back-
                  end, when building a package (default is 9 for gzip and bzip2, 6
                  for xz and lzma).
    
           -Zcompress-type
                  Specify which compression type to use when building  a  package.
                  Allowed  values  are gzip, xz, bzip2, lzma, and none (default is
                  gzip).
    
           --new  Ensures that dpkg-deb builds a 'new' format archive. This is the
                  default.
    
           --old  Forces  dpkg-deb  to  build  an  'old'  format archive. This old
                  archive format is less easily parsed by non-Debian tools and  is
                  now  obsolete;  its  only  use  is  when building packages to be
                  parsed by versions of dpkg older than 0.93.76 (September  1995),
                  which was released as i386 a.out only.
    
           --nocheck
                  Inhibits  dpkg-deb  --build's  usual checks on the proposed con-
                  tents of an archive. You can build any archive you want, no mat-
                  ter how broken, this way.
    
           -v, --verbose
                  Enables  verbose  output.  This currently only affects --extract
                  making it behave like --vextract.
    
           -D, --debug
                  Enables debugging output. This is not very interesting.
    
    
    

    ENVIRONMENT

           TMPDIR If set, dpkg-deb will use it as the directory in which to create
                  temporary files and directories.
    
    
    

    BUGS

           dpkg-deb -I package1.deb package2.deb does the wrong thing.
    
           There  is  no authentication on .deb files; in fact, there isn't even a
           straightforward checksum.  (Higher level tools like APT support authen-
           ticating  .deb  packages  retrieved  from  a given repository, and most
           packages  nowadays  provide  an  md5sum  control  file   generated   by
           debian/rules.  Though this is not directly supported by the lower level
           tools.)
    
           Do not attempt to use just dpkg-deb to install software! You  must  use
