# Automatically change the directory in bash after closing ranger

# This is a bash function for .bashrc to automatically change the directory to
# the last visited one after ranger quits.
# To undo the effect of this function, you can type "cd -" to return to the
# original directory.
# 
# On OS X 10 or later, replace `usr/bin/ranger` with `/usr/local/bin/ranger`.
