rpmcat

One of the ideas that came out of packaging rubygem dependencies for sup and sup itself, was a need of a script that would cat a specific file from an rpm. Since rpmls exists, the next logical step would be a rpmcat.

Rahul told me to go ahead and write it down. He also gave me a few pointers.

Here it is.
Copy it to your /usr/bin/ and do a chmod +x

Usage:
$ rpmcat <RPM> <full-file-path>
(get the full-file-path from rpmls)

Don't try random stuff. It will break! :-P

You can always do this:

$ rpmpeek <rpm> cat <full-file-path>

Why would you want to get a specific file out of an rpm? Why not install the rpm properly?

You have some major defects that will show up on a multi-user system. Also, you can tell cpio to get one file, instead of writing the whole archive out to disk.

@skvidal: To see if some changes I made in a specific file turned out properly. (say sed, etc.)

@others: thanks for the pointers.
