Create multiple pdf files from same tex file - latex

Question

I have multiple data files (result_a.csv, result_b.csv, ..) and I want to create plot for each one (result_a.pdf, result_b.pdf - or similar). The plot is the same but the input file is different and the output file is different. Is there a way I can run a loop, pass the parameter names from the outside and save the output with a distinctive name?
Assume that my code for creating the plot -
\documentclass[tikz]{standalone}
\usepackage{pgfplots}
\pgfplotsset{ytick style={draw=none}, xtick style={draw=none}}
\usetikzlibrary{patterns}
\newcommand\param{a}
\begin{document}
\begin{tikzpicture}
\footnotesize
\begin{semilogxaxis}
\addplot[color=red,mark=triangle] table [x=x,y=y,col sep=comma, mark=*] {result_\param.csv};
\end{semilogxaxis}
\end{tikzpicture}
\end{document}

Answer 1

Assuming your file is called document.tex, you can pass the name of the csv file to the document by compiling with the following command
pdflatex -jobname="document-b" "\\newcommand*\\version{b}\\input{document}"
and the document:
\documentclass[tikz]{standalone}
% setting a default value in case it is compiled without the newcommand
\unless\ifdefined\version
\def\version{a}
\fi
\usepackage{pgfplots}
\pgfplotsset{ytick style={draw=none}, xtick style={draw=none}}
\usetikzlibrary{patterns}
\newcommand\param{a}
\begin{document}
\begin{tikzpicture}
\footnotesize
\begin{semilogxaxis}
\addplot[color=red,mark=triangle] table [x=x,y=y,col sep=comma, mark=*] {result_\version.csv};
\end{semilogxaxis}
\end{tikzpicture}
\end{document}

Answer 2

If you are working under a Linux Distro or under a Mac OS, you may use a shell script.
Let init.tex be the tex file with
\documentclass[tikz]{standalone}
\usepackage{pgfplots}
\pgfplotsset{ytick style={draw=none}, xtick style={draw=none}}
\usetikzlibrary{patterns}
\newcommand\param{a}
\begin{document}
\begin{tikzpicture}
\footnotesize
\begin{semilogxaxis}
\addplot[color=red,mark=triangle] table [x=x,y=y,col sep=comma, mark=*] {
and let ends.tex be the file containing
};
\end{semilogxaxis}
\end{tikzpicture}
The following script reads each .csv file, puts its contents in a tex file organized as follows:
init.tex
result_x.csv
ends.tex
produces the tex file result_xx.tex and compiles it, providing the file result_xx.pdf
#!/bin/bash
for i in $(ls *.csv)
do
a=$(basename -s .csv $i)
cp init.tex $a.tex
echo $i >> $a.tex
cat ends.tex >> $a.tex
pdflatex $a.tex
done
It is a naive solution, there are more experienced than me bash--script writers here in SO, but it should work.
PS. Remember to make the script executable to make it work:
chmod 755 myscript.sh
See for example here.
