rpm Query Command Examples

In lesson 06. RPM, Table: rpm Query Command Example

This example is wrong.
rpm -q --whatprovides libc.so.6
No package provides libc.so.6

The --whatprovides option will show which package provides this file
rpm -q --whatprovides bash

It is long option for the -f option, but must use the full path to the installed file.
rpm -qf /bin/bash

Hi @mike1234432 ,

It also works with libraries, but you need to specify the path. Look at this (on CentOS Stream 8):

[[email protected] ~]$ rpm -q --whatprovides /usr/lib64/libc.so.6
glibc-2.28-167.el8.x86_64

It also can be done with dnf (with the filename only):

[[email protected] ~]$ dnf whatprovides libc.so.6

glibc-2.28-155.el8.i686 : The GNU libc libraries
Repo : baseos
Matched from:
Provide : libc.so.6

glibc-2.28-158.el8.i686 : The GNU libc libraries
Repo : baseos
Matched from:
Provide : libc.so.6

[...]

I'll inform the team of the missing path!

Many regards,
Luis.

Unless I'm dense or there is a difference between RHEL 8 and CentOS-8-stream, I see no problem:

c8:/tmp>rpm -q --whatprovides libc.so.6
glibc-2.28-164.el8_5.3.i686
c8:/tmp>rpm -q --whatprovides bash
bash-4.4.20-2.el8.x86_64
c8:/tmp>rpm -q --whatprovides /bin/bash
bash-4.4.20-2.el8.x86_64
c8:/tmp>

Full path not required at all. I don't see an issue here or anything wrong

Hi @coop ,

Yep, there is a difference between these distros. That's why it won't work the same way on CentOS Stream 8 (and probably 9 as well).

Regards,
Luis.

i investigated this further. RHEL 8 and CentOS 8 stream have the same version of rpm as reported by rpm --version (4.14.3) although C8 has a slighter newer rpm package subrelease, but I doubt the change is there. (CentOS-9-Stream behaves as C8 Stream. Research and the man page for rpm indicate no real explanation of what the argument to --whatprovides should be, but it appears it should be the full path as was pointed out, unless it is a package name (such as "bash"). Probably should clarify this in the future, but apparently until recently the behaviour in RHEL 8 was widely accepted as correct .

btw, RHEL 8.6 which came out yesterday has the CentOS-8-Stream behaviour. These commands seem identical:

rpm -qf /lib*/libco.so.6
rpm --q --whatprovides /lib*/libco.so.6

so the whatprovides option has little value unless you use it with the name of a package, such as bash, rather than a full path.

Hi @coop,

Yep, I have used the command in the past with package names mainly.

thanks @luisviveropena , I was having the same problem using a Fedora system
