An RPM is some sort of cpio archive. On the other hand, a DEB file is a pure ar archive. So, it should be possible to unpack their contents using standard archiving tools, regardless of your distribution’s package format. Under normal conditions, you should use your distribution’s standard package manager, rpm or dpkg and their frontends, to manage those files. But, if you need to be more generic, here is how to do it. RPM[3/7/2014 9:57:58 μμ] How to extract RPM or DEB packages | G-Loaded Journal For RPMs you need two command line utilities, Bluehost ® $3.95 Special rpm2cpio and cpio. Extracting the contents of the RPM package is a one step process: Professional Web Hosting Special Coupon Offer $3.95/mo rpm2cpio mypackage.rpm | cpio -vid If you just need to list the contents of the package without extracting them, use the following: rpm2cpio mypackage.rpm | cpio -vt The -v option is used in order to get verbose output to the stdout. If you don’t need it, you can safely omit this switch. For more information about the options, please refer to the cpio(1) cpio manual page. DEB DEB files are ar archives, which contain three files: debian-binary control.tar.gz data.tar.gz As you might have already guessed, the needed archived files exist in data.tar.gz . It is also obvious that unpacking this file is a two-step process. First, extract the aforementioned three files from the DEB file (ar archive): ar vx mypackage.deb Then extract the contents of data.tar.gz using tar: tar -xzvf data.tar.gz Or, if you just need to get a listing of the files: tar -tzvf data.tar.gz Again the -v option in both ar and tar is used in order to get verbose output. It is safe not to use it. For more information, read the man pages: tar(1) and ar(1) .

Update As Jon suggested in the comment area, the contents of data.tar.gz can be extracted from the DEB package in a one step process as shown below: ar p mypackage.deb data.tar.gz | tar zx That will do it.

There is a command line tool though, called alien, which can convert packages between the RPM and DEB formats. Its use is very straightforward. I highly recommend you give it a shot.

To extract the content run “dpkg-deb –extract mypackage.deb foobar”. If you want to modify the package: dpkg-deb –extract mypackage.deb foobar dpkg-deb -e mypackage.deb foobar/DEBIAN modify files in foobar directory dpkg-deb -b foobar Reply ↓ George Notaras Post author May 9, 2010 at 18:07 Permalink → Hi Benjamin, Having used RPM-based distributions, I was not aware that it was so easy to modify the contents of a DEB package and then repackage the modified files. Thanks for the tip! As for the method of extracting the contents of RPM or DEB I describe in that post, it is meant to be a generic method without requiring any distribution specific tools, but generic archive managers. I had decided to write it because I once needed to extract a DEB package under CentOS; I cannot recall why.

Please revise this to use dpkg-deb or at least show it as an option. dpkg-deb -x Reply ↓ George Notaras Post author August 18, 2010 at 12:18 Permalink → This article describes how to extract a DEB or RPM package using generic archive decompressors. The fact that utilities like rpm or dpkg are not used is intentional. Thanks Reply ↓ Jonathan August 23, 2010 at 19:11 Permalink → “An one-step process” should be “a one step process.” This is because a/an is decided based on the pronunciation of the following word, not on the spelling.

The binutils package is installed by default even in minimal installations on RHEL, Fedora, CentOS and Scientific Linux, so it was kind of impossible for this package to be missing.

Got the tar.deb and unpacked it to get the newer tar binary, so my dpkg would work again. Reply ↓ chauhan June 23, 2013 at 05:44 Permalink → really helpful in extraction.
