"rpm2cpio file.rpm | cpio -i --make-directories" will unpack the rpm to the directory you are momentarily in.

thanks for this it was a great help - Is it possible to modify the files within the rpm and then just 'tar' it back up again or some other such like to repackage it? I need to change something within an rpm but i don't have the spec files etc.

thanks

Don't you have the src.rpm? There's alien, but that really sucks, as you cannot really put scripts into the rpm.

You can, but this is an amazingly bad idea and is one of those "the world is ending, am I REALLY sure I want to do this?" kind of things?

Just to jump in here: I can understand that it shouldn't be the very first thing you do, but I'm curious as to why this is "an amazingly bad idea". Care to hit me with a clue stick?

Almost all opensource RPMS have published SRPMS ... certainly all from CentOS / KBS / RPMForge do.

Where did you obtain said RPM.

Here are the world is ending, please don't ask us to stop the cats and dogs sleeping together instructions:

I normally pull out the files via rpm2cpio into a subtree. I then do rpm -q --scripts and rpm -q --triggerscripts to look at what scripts the RPM was doing. I then create a new rpm out of the list of files (put them in a tar ball, have the %build untar that tar ball and rebuiid. Put the trigger and pre/post scripts into the RPM. Make the changes you need to do to make what you need working for Trendmicro etc. Install rpm on test machine. Fix problems, lather, rinse, repeat.
