dpkg-deb(1) dpkg suite dpkg-deb(1)
dpkg-deb - Debian package archive (.deb) manipulation tool
dpkg-deb [option...] command
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.
For most commands taking an input archive argument, the archive can
be read from standard input if the archive name is given as a single
minus character («-»); otherwise lack of support will be documented
in their respective command description.
-b, --build binary-directory [archive|directory]
Creates a debian archive from the filesystem tree stored in
binary-directory. binary-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 the file 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 binary-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 directory/package_version_arch.deb. 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-field-names 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-field-name 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) with --verbose (-v) which prints a
listing of the files extracted as it goes.
-R, --raw-extract archive directory
Extracts the filesystem tree from a package archive into a
specified directory, and the control information files into a
DEBIAN subdirectory of the specified directory (since dpkg
1.16.1).
The target directory (but not its parents) will be created if
necessary.
The input archive is not (currently) processed sequentially,
so reading it from standard input («-») is not supported.
--ctrl-tarfile archive
Extracts the control data from a binary package and sends it
to standard output in tar format (since dpkg 1.17.14).
Together with tar(1) this can be used to extract a particular
control file from a package archive. The input archive will
always be processed sequentially.
--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
sequentially.
-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.
-?, --help
Show the usage message and exit.
--version
Show the version and exit.
--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 use on the compressor
backend, when building a package (default is 9 for gzip, 6 for
xz). The accepted values are 0-9 with: 0 being mapped to
compressor none for gzip. Before dpkg 1.16.2 level 0 was
equivalent to compressor none for all compressors.
-Scompress-strategy
Specify which compression strategy to use on the compressor
backend, when building a package (since dpkg 1.16.2). Allowed
values are none (since dpkg 1.16.4), filtered, huffman, rle
and fixed for gzip (since dpkg 1.17.0) and extreme for xz.
-Zcompress-type
Specify which compression type to use when building a package.
Allowed values are gzip, xz (since dpkg 1.15.6), and none
(default is xz).
--uniform-compression
Specify that the same compression parameters should be used
for all archive members (i.e. control.tar and data.tar; since
dpkg 1.17.6). Otherwise only the data.tar member will use
those parameters. The only supported compression types allowed
to be uniformly used are none, gzip and xz.
--deb-format=format
Set the archive format version used when building (since dpkg
1.17.0). Allowed values are 2.0 for the new format, and
0.939000 for the old one (default is 2.0).
The 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.
-v, --verbose
Enables verbose output (since dpkg 1.16.1). This currently
only affects --extract making it behave like --vextract.
-D, --debug
Enables debugging output. This is not very interesting.
0 The requested action was successfully performed.
2 Fatal or unrecoverable error due to invalid command-line
usage, or interactions with the system, such as accesses to
the database, memory allocations, etc.
TMPDIR If set, dpkg-deb will use it as the directory in which to
create temporary files and directories.
SOURCE_DATE_EPOCH
If set, it will be used as the timestamp (as seconds since the
epoch) in the deb(5)'s ar(5) container and used to clamp the
mtime in the tar(5) file entries.
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.
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.)
