I've RPM file of which I want to examine its file contents. For
.deb packages, I can use
dpkg -x file.deb to extract it.
What is the equivalent command for a
.rpm file? I'm looking for a command-line application.
file-roller seems to open rpm files. Alternatively you can use the command:
$ sudo apt-get install rpm2cpio $ rpm2cpio /path/to/file.rpm | cpio -i --make-directories
that will extract the rpm content to the current directory.
As far as I remember you have to use a app called alien which transforms .rpm to deb files. Use a terminal to do :
sudo apt-get install alien
sudo alien -d nameofyourpackage.rpm (-d for Debian package)
If you then need to examine it you can resort to your dpkg -x file.deb method
You can also use alien to only extract the files (which it calls "generate a build tree")
alien --scripts --generate <package.rpm>
You will get 2 dirs -
<package>.orig, which is the raw extraction from the rpm.
apt install p7zip-full
7z x /path/to/file.rpm 7z x /path/to/file.cpio -o/path/to/extract/folder/
