Open Finder window from current Terminal location?

If I am in a specific path in a Terminal window, how can I open that same window in a new Finder window?

Note: This is the opposite of opening a Terminal from Finder.

Typing open . in Terminal will open the current working directory in a Finder window.

Stretch goal!

To expand on the answer above (because the more appropriate related question is marked as a dupe and can't receive new answers)...

I've added a function to my ~/.bash_profile to handle revealing a file or directory:

# Reveal a file or directory in Finder
reveal() {
  # grab the first arg or default to pwd
  local basedir=${1:-${PWD}}

  if [[ -f "$basedir" ]]; then
    # ..we passed a file, so use its containing directory
    basedir=$(dirname "$basedir")
  fi
  # basedir is a directory in now, so open will activate Finder.
  # The argument is quoted to accommodate spaces in the filename.
  open "$basedir"
}

…one liner:

reveal() { local dir=${1:-${PWD}}; [[ -f "$dir" ]] && dir=$(dirname "$dir") || true; open "$dir"; }

To install the function:

• paste/save it into ~/.bash_profile
• source ~/.bash_profile or open a new terminal/tab

The context for my use is that I'll be browsing around using ls with tab completion, then when I find what I'm looking for, I can reveal (or cd or subl) the most recent arg, like:

ls dir/subdir<tab tab>
subsubdir  anotherdir
ls dir/subdir/anotherdir
reveal !$

If you have autojump installed, you don't even have to type the full path to the directory. You can simply type jo partialdirectoryname, and autojump will open a new Finder window in the specified directory.

I love this method, because you don't have to remember the entire directory name. Autojump keeps a list of most commonly used locations, and automatically knows which directory you're referring to, even if you only give it part of the name.

open .

As a nice addition, add an alias in .bash_profile or .bash_aliases if you have one.

alias finder='open'

Then you can use finder . which I think is more intuitive.
