Keep Mac OS X Finder and Terminal in sync

findercd.scpt

(*
Script: findercd.scpt

This script sets the target of the front window of Finder
to the directory path passed as the first argument. If
there is no Finder window, one is created. Optionally
the finder window can be activated by passing in "true"
as second argument. If no argument is passed
the user is prompted to select a directory
to go to.

The following two bash functions can be used to
invoke this script from bash running in Terminal
window:

# Change the directory of front window of
# Finder to pwd of shell
fcd() {
     cd "${1}"
     osascript ~/scripts/finder/findercd.scpt "`pwd`" ${2}
}

# Change the directory of front window of
# Finder to pwd of shell and activate the
# Finder window
fcda() {
     fcd "${1}" true
}

Installation:

1. Paste this script in Script editor
2. Save it as a script - ~/scripts/finder/findercd.scpt
3. Add the fcd() and fcda() functions mentioned above
   to your .bashrc or .bashrc_profile

This script complements the terminalcd.scpt script.
