Usage of 'rpm -q --whatprovides'

akamch · September 2020

What does libc.so.6 mean as a 'particular requisite package'? (WRT section 'Queries' in RPM module).

The --whatprovides option will show what installed package provides a particular requisite package:

$ rpm -q --whatprovides libc.so.6

I've got the following result:

$ rpm -q --whatprovides libc.so.6
no package provides libc.so.6

'man rpm' mentions '[--whatprovides CAPABILITY]' syntax where CAPABILITY is something like this:

$ rpm -q --whatprovides webserver
httpd-2.4.6-93.el7.centos.x86_64

This also works (but 'rpm -qf' may be simpler in this case):

$ rpm -q --whatprovides /lib64/libc.so.6
glibc-2.17-307.el7.1.x86_64

Hmmm, can you try with
$ rpm -qf /lib64/libc.so.6 ???

Yep, libc.so.6 is now provided by glibc. I tested this on CentOS 7:

[luis@centos7server ~]$ locate libc.so
/usr/lib/x86_64-redhat-linux6E/lib64/libc.so
/usr/lib64/libc.so
/usr/lib64/libc.so.6

[luis@centos7server ~]$ rpm -qf /usr/lib64/libc.so.6
glibc-2.17-307.el7.1.x86_64

Regards,
Luis.

Is this a PATH 'problem'? Or is the full path always necessary with the --whatprovides argument?

Yes, it is a $PATH thing, not a problem as such. I always use the full path name.
