TEMP_BIB_PATH=".mybib.bib"
TEMP_MD_PATH=".mybib.md"

clean() {
    rm -rf $TEMP_BIB_PATH $TEMP_MD_PATH $TEMP_CITATION_PATH

clean

while read line
do
    echo "$line" >> $TEMP_BIB_PATH
done < "${1:-/dev/stdin}"

cat > $TEMP_MD_PATH <<- EOF
---
title: Citations
bibliography: $TEMP_BIB_PATH
nocite: '@*'
...
EOF

pandoc --filter=pandoc-citeproc -t markdown-citations --standalone $TEMP_MD_PATH | tail -n +9 > $TEMP_CITATION_PATH
cat $TEMP_CITATION_PATH | head -$(($(wc -l < $TEMP_CITATION_PATH) - 2)) $TEMP_CITATION_PATH

clean

This depends on pandoc being installed.

The BibTeX entry can be input from stdin or a file can be provided.
