I have  >> apache:x:48:48:Apache:/usr/share/httpd:/sbin/nologin << and do not
think to modify it

Ok

Yes, that is what I need

How, where?

Yes.
I have a .php script

<?php
......

$test2 = `/usr/local/texlive/2019/bin/x86_64-linux/pdflatex  --interaction
batchmode myFile.tex`;
$test21 = `sudo -u root /usr/local/texlive/2019/bin/x86_64-
linux/biber   myFile.bib`;
$test22 = `/usr/local/texlive/2019/bin/x86_64-linux/pdflatex  --interaction
batchmode myFile.tex`;
.....
?>

How would you define the necessary variables therein?

Note: everything works fine, even from within the .php script, if I call a older
2016 version of texlive.

thanks
mario
