I am trying to install texlive in order to recover files swept away in the process of installing another latex software package.
The basic problem is that I want to run tlmgr to recover lost packages, but the command line does not recognize this command.
Now, I am pretty sure I installed texlive before, but I can't be certain.
A locate search turns up many results, the most numerous being in a folder called "textmf-texlive."
I am following the installation process on this page: http://www.tug.org/texlive/quickinstall.html
I am running this perl script:
install-tl-20130114
It says on the page that I should remove previous installation.
But I don't see any files like the ones on the page.
I see only the previously mentioned "textmf-texlive" folder, which I am not certain that it has anything to do with actual texlive, especially since tlmgr will not run.
So I think I can just go ahead and run the script.
At the end of this page it says I have to set a PATH.
This I am sure I did not do, which might be the reason tlmgr does not work.
I am on Ubuntu 12.04. After I run the installer, can I just copy and paste the code on the web page to set the PATH?

Since you seem to have some troubles with the concept of
$PATHetc, you will be much better off by using the Ubuntu packages; see this question and its answers.
