Alright I'm making a list which I'm going to post up so all noobs can have a source of codes that they can use if they encounter the same problem as myself. So can I get an example of a situation.
Let's say I installed zenbound demo.
I would type in:
1) "sudo rainroot"
2) "find /|grep zenbound
3) Then after I find it and I get the exact name of file
4) dpkg -P zenbound

where did I go wrong?

Actually if you already know the name.. you would only need
1. sudo gainroot
2. dpkg -P zenbound

If you are not sure but you know it starts on "zen" then..
1. sudo gainroot
2. dpkg -l |grep zen or the nicer one dpkg -l | awk '{print $2}' | grep zen
would give you the full name

If you are just looking for a file and don't know where it is..
1. sudo gainroot (is needed when you look outside /home to have permission)
2. find / |grep zen
this would give a lot of places and file names with "zen". Like icons, config files, post/pre install files e.t.c...

Nice nice good stuff. Anything else I and any other noob should know?

K goodnight later

You can also use "apt-cache search" to look for packages - that'll check both the package name and the description.
