Autobuild RMarkdown presentations

autobuild.sh

#!/bin/bash

### Set initial time of file
LTIME=`stat -c %Z ./$1.Rmd`

while true    
do
  ATIME=`stat -c %Z ./$1.Rmd`
  
  if [[ "$ATIME" != "$LTIME" ]]
  then    
    Rscript -e "rmarkdown::render('$1')"
    LTIME=$ATIME
  fi
  sleep 5
done

I think that index.html and index.Rmd needs to be changed to $1 . . .
