## Installing TeX locally

The default TeX install that comes with our desktops in the CAAM department is antiquated: may packages are missing and those we do have are several years behind. Early on, this isn't much of a problem, but once you get more advanced, you'll want to use more of the features available in modern TeX.

### Local install

Hard drive space in your home directory is limited, so we will do the instillation in the /scratch directory. This is located on the physical hard drive associated with your desktop. Start by downloading the current TeXLive sources:

caampc # cd /scratch caampc # wget http://mirror.ctan.org/systems/texlive/tlnet/install-tl-unx.tar.gz

Now unpack this file

caampc # gunzip install-tl-unx.tar.gz caampc # tar xfv install-tl-unx.tar

Go to the directory this extracts and run the install script

caampc # cd install-tl-* caampc # ./install-tl

We now need to change a few of the install settings. By default, TeXLive wants to install to /usr/local/texlive. We don't have write access to that directory, so we'll install to the /scratch directory. Select D and then 1 and change the directory to /scratch/texlive. As we live in the United States, it also makes sense to configure the default paper size to letter instead of A4. Select O and then P to change the default. Now, select I to install and go have lunch. This takes a while!

### Updating Path

The last step is to update our path such that our installed version of TeX is called when we run latex. In the ~/.bashrc file (assuming you're using bash), add the following line

export PATH="/scratch/texlive/bin/x86_64-linux/:$PATH" We need to add our new path to the left of the existing path so that it is scanned first; see 1. While we're editing the bashrc file, it is a good time to add new directories for TeX and BibTeX to search. export TEXINPUTS=".:$HOME/SVN/matpic:$HOME/SVN/dagr/TeX:$TEXINPUTS" export BIBINPUTS=".:$HOME/SVN/dagr/TeX:$BIBINPUTS"

### Updating

To update texlive, run the program

tlmgr update --all
