NAME

       dpkg-deb - Debian package archive (.deb) manipulation tool

SYNOPSIS

       dpkg-deb [options] 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
              contains  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
              problems, 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
              overwritten.

              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
              summary 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.

       -W, --show archive
              Provides information about  a  binary  package  archive  in  the
              format  specified  by  the  --showformat  argument.  The default
              format displays the package's name  and  version  on  one  line,
              separated by a tabulator.

       -f, --field archive [control-field-name...]
              Extracts control file information from a binary package archive.

              If  no  control-file-fields are specified then it will print the
              whole control file.

              If any are specified then dpkg-deb will print their contents, in
              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
              generated 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
              package.

       -X, --vextract archive directory
              Is  like  --extract  (-x)  but  prints  a  listing  of the files
              extracted as it goes.

       --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.

       -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
              Show the usage message and exit.

       --version
              Show the version and exit.

OPTIONS

       --showformat=format
              This option is used to specify the format of the  output  --show
              will  produce.  The  format  is a string that will be output for
              each package listed.

              The string may reference any status field  using  the  "${field-
              name}"  form,  a list of the valid fields can be easily produced
              using -I on the same package.  A  complete  explanation  of  the
              formatting   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  pass  to  the compressor
              backend program, when building a package.

       -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
              contents of an archive. You can build any archive you  want,  no
              matter how broken, this way.

       -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
       authenticating .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
       dpkg proper to ensure that all the files are correctly placed  and  the
       package's scripts run and its status and contents recorded.
