# `l3sys-query`: System queries for LaTeX using Lua
Release 2024-03-04
## Overview
The `l3sys-query` script provides a method for TeX runs to obtain system
information _via_ shell escape to Lua. The facilities are more limited than the
similar Java script `texosquery`, but since it uses Lua, `l3sys-query` can be
used 'out of the box' with any install TeX system. The script is written taking
account of TeX Live security requirement; it is therefore suitable for use with
restricted shell escape, the standard setting when installing a TeX system.
The supported queries are
- `ls`: Directory listing supporting a range of options
- `pwd`: Obtaining details of the current working directory
## Issues
The issue tracker for LaTeX is currently located
[on GitHub](https://github.com/latex3/l3sys-query/issues).
