I just dont simply understand, I have searcht te forum and google but I cant seem to find it,

I have downloaded limewire for linux, its a .rpm

I have found on the form:
but it says (even if I am logged in as a root):
bash: rpm: command not found

can someone tell me in a newbie way how to use a .rpm

(I am running debian with several windowmakers)

Rpm is a Red Hat software package management system. so since you are running Debian, I would say you do not have this installed. You should be able to do one of two things: either install the rpm package management system by running
or by seeing if there is a Debian package (.deb) available for the software you want to install. There may also be a program to convert the .rpm into a .deb file. I am not a Debian or Red Hat user, so really can't give you anymore specifics, but these are just some possible solutions I thought of.

yay, I have made a .deb file of it with alien,

but how do I install the .deb file?

Well, not a Debian user, but I think you would use the command to do it. Try running to view the documentation for the apt command, and that should point you in the right direction.

can seem fo figure it out

can someone help me?

should do the trick.

ah, thanks
