Execute Shell from LaTeX

This LaTeX package helps you execute commands from the document and then input their output. The package uses the shellesc package. The development of this package was motivated by this.

First, install it from CTAN and then use it in the preamble:

\documentclass{article}
\usepackage[unskip]{iexec}
\begin{document}
Today is \iexec{date +\%e-\%b-\%Y}.
\end{document}

Otherwise, you can download iexec.sty and add it to your project.

The full example and all commands are available in the iexec.pdf file.

If you want to contribute yourself, make a fork, then create a branch, then run l3build check in the root directory. It should compile everything without errors. If not, submit an issue and wait. Otherwise, make your changes and then run l3build check again. If the build is still clean, submit a pull request.
