How to get one file out of a large rpm file or cvs distro?

RileyTheWiley · 01-05-2008, 04:28 PM

I am in need of a particular single file (editraise.xpm in the Qt tree, if it matters) that I don't have. I can find it within an RPM or a cvs site somewhere (don't recall offhand).

I would like to know the easy way to extract and unpack that single file onto my system.

How to do it?

Thanks

Eric

Use rpm2cpio and cpio;

rpm2cpio < the_rpm_filename_here > something.cpio
cpio -i -d < something.cpio

Or in one-line piped command

Code:

rpm2cpio qt2-designer-2.3.0-3mdk.i586.rpm | cpio -idmv *editraise.xpm

this will extract the files called editraise.xpm (there are two of them in the package) with the directory structure as in the original package, but relative to the current directory. In other words, you will get the following:

Code:

# find . -type f
./usr/lib/qt2/tools/designer/pics/large/editraise.xpm
./usr/lib/qt2/tools/designer/pics/small/editraise.xpm
./qt2-designer-2.3.0-3mdk.i586.rpm

I've always just used file-roller:

There is also a program called "unrpm" that combines the rpm2cpio and the cpio commands. You may have it already. The "mc" console filemanager can also extract files from an rpm package. Select the rpm file, and then CONTENTS.cpio in the package.
