Scrappy script to open stdin into whichever is associated with .html extensions (MacOS)

browser.sh

#!/bin/bash
set -e

RANDOMNAME=$(mktemp).html || exit 1
cat /dev/stdin > $RANDOMNAME
open $RANDOMNAME 

# to open with an other browser (or program) replace the above line with
# something like ...
# open -a safari $RANDOMNAME
# open -a firefox $RANDOMNAME

# inelegant and not foolproof (i.e. if the browser takes longer than the
# sleep time to open the file, it'll be _gone_)
trap "sleep 2.4s && rm $RANDOMNAME &" EXIT
