OSX “open” command to create new files with an app

alias text='open -a /Applications/TextWrangler.app'

I think you want a full-fledged shell script rather than just an alias. Make a file with these contents:

if [ -e "$1" ]; then
  open -a TextWrangler -- "$1"
else
  touch "$1"
  open -a TextWrangler -- "$1"
fi

Save it as text somewhere in your PATH and chmod it to be executable and you're golden.

If you really want to make it so that the file doesn't exist if you don't save it, that's trickier. I think you'll have to do something like this:

if [ -e "$1" ]; then
  open -a TextWrangler -- "$1"
else
  touch "$1"
  open -a TextWrangler -- "$1"
  sleep 1
  rm "$1"
fi

This will actually create the file and then delete it one second later. The app will still have the file open, though, so that when you save it will be recreated.

How about just create a function instead of an alias in your starup file (.bashrc, .profile etc).

newf() {
    echo "$1" | xargs touch; open -a "/Applications/TextWrangler.app" "$1"
} 

Once added, source your startup script and just do the following to use this -

newf dummyfile.txt

and Text Wrangler will pop up with an empty file called dummyfile.txt.
