finding rpms

Hi all...

I am trying to find the required rpms for some binaries..

Code:

[vinay@TEG ~]$ rpm -q --whatrequires /bin/ls

redhat-lsb-3.1-19.fc8.i386

jre-1.6.0_14-fcs.i586

Code:

[vinay@TEG ~]$ rpm -q --whatrequires /sbin/ifconfig

no package requires /sbin/ifconfig

why ifconfig does not require any package ???!!!

--whatrequires is the way around you are thinking. It is not that ifconfig does not require any package but it is that no package requires ifconfig.

Thanks linuxlover.chaitanya...

Then you mean

Code:

[vinay@TEG ~]$ rpm -qf /sbin/ifconfig

net-tools-1.60-87.fc9.i386

[vinay@TEG ~]$ rpm -qf /bin/ls

coreutils-6.10-18.fc9.i386

ifconfig requires net-tools-1.60-87.fc9.i386.rpm right....

then when --whatrequires is exactly required...?

Code:

[vinay@TEG ~]$ rpm -q --whatrequires /bin/ls

redhat-lsb-3.1-19.fc8.i386

jre-1.6.0_14-fcs.i586

Does this indicates redhat-lsb-3.1-19.fc8.i386 and jre-1.6.0_14-fcs.i586 requires coreutils-6.10-18.fc9.i386 installed....? I am confused please help me...

From man page:

Quote:

--whatrequires CAPABILITY
Query all packages that requires CAPABILITY for proper function-
ing.

It will give the list of all the packages that are dependent on the package mentioned in the command for the proper functioning.

@vinaytp: Based on your postings you will need to use both --whatprovides CAPABILITY and --whatrequires CAPABILITY - either to find out what package holds a certain tool and which other tools depend on that tool.

Here

Code:

whatrequires

is required to check the dependencies of that package,

If u want to know the package name of the binary,

use

Code:

rpm -qf <binary>

or
use (to search any rpm package is installed or not)

Code:

rpm -qa | grep <package name>

Dear All...

Thanks for your inputs...But I hope we cannot mention package name with --whatrequires option

This provides on which pkg ifconfig depends...

Code:

rpm -q --whatprovides /sbin/ifconfig

net-tools-1.60-87.fc9.i386

Also
This tells redhat-lsb-3.1-19.fc8.i386 and jre-1.6.0_14-fcs.i586 requires /bin/ls capability installed

Code:

[root@TEG vinay]# rpm -q --whatrequires /bin/ls

redhat-lsb-3.1-19.fc8.i386

jre-1.6.0_14-fcs.i586

Hope I am correct...Please guide me if I am wrong....

Package here I meant ls or ifconfig that you were referring to. I should have meant binary.

The first:

It says the capability of ifconfig is provided by net-tools. It means ifconfig needs net-tools package installed for proper functioning.

While in the second example:

The packages in the output of the command require ls for the proper functioning.
