Environment Modules

For some software multiple versions are available. To use it, the environment has to be set up. This is easily achieved using environment modules. For example, to use GCC 4.9 execute

module load gcc/4.9
module avail list available modulues
module load <name> load specified module
module unload <name> unload specified module

If the module command is not available in your shell, make sure it loads /etc/profile, or loads /usr/share/modules/init/<shell> in some other way.

You can load modules in your init files (.bashrc and so forth) to set up a common session.


TeX Live

The TeX live version currently installed in the institute is TeX Live 2007. Even after the planned update of Debian this will only upgrade to TeX live 2009. Therefore there is a local current TeX live installation available in /opt/texlive/current.

To use the current TeX live distribution (2011) setup paths

source texlive-paths

The best way to do this is to add it to your ~/.profile file and load it in your shell. You can accomplish it in the following way:

echo "source texlive-paths" >> ~/.profile

In order to load the settings from the ~/.profile file in your shell add:

source ~/.profile

to your ~/.bashrc or ~/.zshrc file.

To use it with KDE, you can do the following:

[ -d ~/.kde/env ] || mkdir -p ~/.kde/env

cat > ~/.kde/env/ <<EOF

source ~/.profile

chmod +x ~/.kde/env/

Please do close unused Mathematica sessions. To check license usage use the monitorlm utility. If Mathematica is killed, it will take some time until the license returns to the pool (possibly about 15 minutes).

Emacs like keys for 'konsole" and zsh

Add the following to your ~/.inputrc:

## for ITP
# alt + right
"^[[1;3C": forward-word
