Post build processes with shell script and write18

Question

I would like to start a shell script from LaTeX. In the shell script I need to wait until the .pdf file is generated and afterwards I want to do some stuff with this file.

So I created a MWE Test.tex like this:

\documentclass{article}
\immediate\write18{/myPath/script.sh}
\begin{document}
  Test
\end{document}

The shell script script.sh looks like this:

#!/bin/bash
until [ -f Test.pdf ]
do
     sleep 5
done
echo "File found"
# Do SOMETHING

Unfortunately this seems not to work with TeXMaker. It seems to hang in an endless loop and probably the sleep 5 cmd seems also to let TeXMaker fall asleep.

BTW --shell-escape is enabled and chmod 755 script.sh is set.

EDIT Now I'm able to use arara like this in my MWE:

\documentclass{article}
% arara: pdflatex: {shell: yes,synctex: yes,interaction: nonstopmode}
\begin{document}
Test
\end{document}

But how to tell arara now to run this script \immediate\write18{/myPath/script.sh} after the pdf is generated?

Answer 1

Thanks for the comments, at the end the solution is much easier than expected.

I had to change my IDE from TexMaker to TexStudio. In TexStudio you just has to add one single expression in the Meta Commands in Preferences => Generate => Build and View.

In my case it's sh -c "/MyPath/script.sh argument1"

That's it!
