I think rpminfo is not working, because it does not return any output. For exemple, profanity's package contains a binary, so I expect -e option to print something in the terminal:
% rpminfo -v profanity-0.11.1-2.fc36.x86_64.rpm % rpminfo -v -e profanity-0.11.1-2.fc36.x86_64.rpm % rpminfo -v -i profanity-0.11.1-2.fc36.x86_64.rpm % rpminfo -v -p profanity-0.11.1-2.fc36.x86_64.rpm % rpminfo -v -np profanity-0.11.1-2.fc36.x86_64.rpm % rpminfo -v -r profanity-0.11.1-2.fc36.x86_64.rpm % rpminfo -v -r -t profanity-0.11.1-2.fc36.x86_64.rpm % rpminfo -v -ro -t profanity-0.11.1-2.fc36.x86_64.rpm
No output is printed in the terminal after theses commands.
Something should be printed. The profanity's package (used here as an exemple) contains a binary:
% rpmfile profanity-0.11.1-2.fc36.x86_64.rpm | grep bin /usr/bin/profanity 100755 ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=c05912979dab5ec4a1d79413c14056c526fc5913, for GNU/Linux 3.2.0, stripped
It looks like rpmfile succeded to open and read the package file, but rpminfo cannot.
Additional infos:
% which rpminfo /usr/bin/rpminfo
% rpm -qf /usr/bin/rpminfo rpmdevtools-9.6-1.fc36.noarch
% file /usr/bin/rpminfo /usr/bin/rpminfo: Bourne-Again shell script, ASCII text executable
The script is using these tools installed on my system:
% rpm -qf /usr/bin/readelf /usr/bin/eu-readelf /usr/bin/objdump binutils-2.37-37.fc36.x86_64 elfutils-0.188-3.fc36.x86_64 binutils-2.37-37.fc36.x86_64
