rpm - single file installation from rpm package

[Matthias Bayer]

Hi,

i am searching for a possibility to install just one file out of an rpm-package without having to install all files out of the rpm package, does anybody know how to do this ?
example:
i want to replace my /bin/mount' command on my running system out of the package 'mount-2.11y-31.1.i386.rpm' from the CD without installing all other files from 'mount-2.11y-31.1.i386.rpm'.

thanks for any help.

regards,
Matthias

Hi
Using rpmget script, you can easily extract a specified file from a rpm.

Hi Matthias

I personally don't have the rpmget script, so I use the following method.

Run this command against the package from which you want to extract the mount command:

rpm2cpio |cpio -i --make

Preferably run this in say your /tmp directory, as the --make command makes all the directories as mentioned by the paths of files within the rpm package.

For instance, mount is located in /bin/mount, so the above command will create a bin directory relative to /tmp, i.e /tmp/bin. Within this directory you'll find the mount command. Either mv or cp it to the original location, as you prefer. Once complete, you can just clean up your /tmp directory again.

This is an option if like me, you don't have rpmget, otherwise that would be a preferable option.

you could also use mc (midnight commander) to select any number of files inside the rpm and extract them. behind the scene mc will call cpio for you.
