RE: RPM files md5sum

[Eran Ben Natan <eranb@xxxxxxxxxxxx>]

It will work only if when running the %post the rpm is considered "installed" and can be queried with rpm -q

Another option is: At the end of the %install calculate yourself the checksum of all files (it should be simple with something like: find %{buildroot} -type f -exec mdsum {} \; ) into a file, package this file, and in the %post copy this file somewhere else so it won't be deleted when rpm is uninstalled.

 

Hope this helps, Eran.

Hi,

I know that the rpm stores the ckecksums, but for this I need to keep the rpm.

I would need to have a separate file with all these check sums and if the rpm is deleted I can check this file.

Also, I would like to create this file during the rpm installation. I am the one who builds the rpm and I can modify the

SPEC file.

I would need to add something similar to your command, but in the SPEC file, in the %post section. Is there
any way?

With kind regards,
Dragos

I am not entirely sure what you actually want to achieve but rpm already
stores the check sums of all installed files. You can get them with e.g.

rpm -q --qf "[%{FILENAMES}\t%{FILEDIGESTS}\n]" rpm

Also rpm --verify is capable to check them against the installed files.
