So: Is it possible to switch between tetex/texlive on a running system?


If you have decent hardware, virtual machines are a very robust way to support tetex and texlive. The VMware player is easy to install and there are a number of prepackaged runtimes for various linux versions.

I know vmware - it's a great program...

In general you get a base install and a modest virtual disk sufficient to hold a tex install. At work I have TL2005 with multiple binaries on a server, so I just mount the partion with TL2005 in a VM, set the PATH, and go.

It's something like that I wanted... I'm a student so I can't tell somebody to put texlive on a server for me to mount whenever I want it...

But: I have a an AMD64 computer at home that has plenty of harddisk space. I don't have any server so I guess I would just have to install it inside the virtual machine if that's the solution I pick (I first want it on my dualboot win/linux laptop but only on the linux-partition).

If you have mundane hardware, you can still have multiple TeX distros, but more effort is required. In general, it should only be necessary to change the PATH variable to switch between the tex system that runs from /usr/bin and an alternative that keeps the binaries in a separate location (e.g., texlive). You do have to watch for the locations of generated files. TeX Live 2005 uses $HOME/.texlive2005/texmf-var. I think teTeX-3 uses a different convention to avoid conflicts.

That was exactly my concern - if they were using some of the same files and if they could make any conflicts. But based on all the answers I got, it seems like I just have to worry mainly about thet path...

The "environment modules" package is convenient for one-the-fly switching, but unless you are on SGI IRIX64 you probably have to install from sources
(there is a tk/tcl version).

I don't even know what SGI IRIX64 is and I've only heard about tk/tcl (and used it slightly without knowing what I did).

$ module list
Currently Loaded Modulefiles:
1) use.own 2) TeX/TL2005 3) GS/8.54

Erhm... Newbie question: What does the command "module list" do? I don't think I've ever used that.

$ which tex
/usr/local/texlive/2005/bin/i386-linux/tex

I know what that means :-)

$ module rm TeX

Dunno what it means...

$ which tex
/usr/bin/tex

I know what it means... I could expect that all tex-distributions make a symbolic link to /usr/bin/tex, right?

$ module load TeX/TL2005
$ which tex
/usr/local/texlive/2005/bin/i386-linux/tex

I think I need to find out what that "module" command does... Is it a running a script?
