# How to install LaTeX .zip package (from CTAN) using texhash on a 'nix system?

Is there an automated script which places files in the relevant directory tree in ~/texmf/ and is that all that is required to install a package (in addition to calling texhash on ~/texmf/)?

Only some packages on CTAN come also in so called TDS ZIP files which already hold the required directory structure so that you only need to unzip them over your `\$TEXMF` tree (e.g. `~/texmf`). If the package author didn’t uploaded a TDS ZIP file it most likely isn’t on CTAN.

To my knowledge there is no direct script available which turns a CTAN package into the required TDS structure and installs it directly. (The TeXLive developers should have something like that to build the TeXLive package files.)
I was thinking writing such a script recently. So far I wrote a Makefile which does it for most LaTeX packages, but currently it is `ydoc` specific, i.e. for my packages only.

However, you could download the whole CTAN directory for a package as a flat ZIP file, unpack it and then use the `ctanify` script on the directory. It is intended to create an upload ZIP file for CTAN which also includes a TDS ZIP file.
You then can use this TDS ZIP file and unpack it over your TEXMF tree.

I just tested this using `colortbl` as a random example. The steps are as follows and could be turned into a script easily. Simple add `#!/bin/sh` as first line and replace `colortbl` with `\$1` and call it using `yourscriptname <name of package>`. However, most but not all LaTeX package are located in `/macro/latex/contrib`, so for the others you would need to provide the download link somehow.

``````cd /tmp
wget http://mirror.ctan.org/macros/latex/contrib/colortbl.zip
unzip colortbl.zip
cd colortbl/
tex colortbl.ins
ctanify *.ins *.dtx
tar -xzf colortbl.tar.gz
unzip -d ~/texmf colortbl.tds.zip
test -e ~/texmf/ls-R && texhash ~/texmf
``````

Note that you only need to run `texhash` for the per-user TEXMF directory if the `ls-R` file already exists. Modern TeXLive installation search it automatically every run if the `ls-R` file doesn’t exists.

Slightly longer answer: If your package is on this list, kind of. The `tds.zip` files already have the structure of the TeX Directory Structure built in, so when you unzip it in the root of your `texmf` tree, all the files go in the right places. So if you download that zip file, then it should work.
