→Environment Variables
Most options in <tt>texmf.cnf</tt> of modern TeX distributions also work with ConTeXt.
== Environment Variables ==
By default, ConTeXt creates a directory named <tt>luatex-cache</tt> in the user's home directory. One way to change the cache location includes:
export TEXMFCACHE=/tmp
mtxrun --generate
context filename.tex
Another way is to run the <tt>context</tt> executable indirectly via <tt>mtxrun</tt>, as follows:
export TEXMFCACHE=/tmp
mtxrun --autogenerate --script mtx-context filename.tex
Running ConTeXt in either of these ways will create <tt>luatex-cache</tt> inside the <tt>/tmp</tt> directory, rather than the user's home directory.
== Security Concerns ==
ConTeXt requires enabling the `write18` function to run [[MetaPost]] and other tools. This implies that malicious TeX code can run any program with user rights into the security safe [coffre de sécurité coffre-fort de sécurité]. The function is ''disabled'' by default. This can be enabled by changing the setting inside <tt>texmf.cnf</tt>:
