Installation:

brew install browser

Or, if you must:

 sudo curl https://gist.github.com/raw/318247/browser -o /usr/local/bin/browser
 sudo chmod +x /usr/local/bin/browser

Just in case anyone can't figure this out:
TextMate command:
cat $TM_FILE | /usr/local/bin/browser

Small point, but "...hi mom!..." should be '...hi mom!...' in the usage example in the comments. Strong quoting is needed to avoid the dreaded "bash: !: event not found" error.

/Users/humza/homebrew/bin/browser: line 2: syntax error near unexpected token '<'
'Users/humza/homebrew/bin/browser: line 2: '

301 Moved Permanently' I get this for some reason

The URL for installation should be https:

sudo curl https://gist.github.com/raw/318247/browser -o /usr/local/bin/browser
sudo chmod +x /usr/local/bin/browser

In bash you can do <(foo) to achieve the same as zsh's =(foo). But it doesn't work with the open(1) utility for me. How should it figure out the file type anyway?

Zeokat usefull piece of code.

Try

:; I="$(basename $0)"; [ -z $BROWSER ] && open=open || open=$BROWSER

[ $# -eq 0 ] && set -- -; [ "$1" = "-" ] && [ -t 0 ] &&
  echo "Usage: [ COMMAND | $I ] | [ $I < FILE ] | [ $I FILE ... ]" >&2 && exit

for what; do where="/tmp/$(od -N2 < /dev/urandom | openssl dgst -sha1).html"
  cat "$what" > "$where" && $open "$where"; sleep 1 && rm -f "$where" & done

Some advantages:

• Respect $BROWSER. Can be BROWSER=lynx, BROWSER='open -a Firefox', etc.
• No bashisms ($RANDOM) or zsh-isms (=(...)).
• Correctly handles arguments that do not end in .html.
• Correctly handles multiple arguments and shell globs.
• Cleans up after itself.
  
• Doesn't even need a shebang!

Or, you might prefer what I use: avoid leaving your terminal at all, and:

cat "$what" > "$where" && qlmanage -p "$where" >/dev/null 2>&1; sleep 1 ...
