Highlighting bash code with knitr / rmarkdown

Question

I\'m trying to generate an HTML report using RStudio, R Markdown and knitr. In the report I would like to display some bash code. I do not want to run the code

Answer 1

The default syntax highlighting theme does not work well for non-R code chunks, and you can use other themes, e.g. pygments

---
title: "Bash Highlighting"
output:
  html_document:
    highlight: pygments
---

```{r, engine = 'bash', eval = FALSE}
for foo in (ls bar)
do
  echo $foo
done
```
