#to install ack, see http://betterthangrep.com/
#to use ack, launch terminal (mac osx) and type 'ack <some_keywords>'
#ack will search all files in the current directory & sub-directories

#here's how I have my config file setup. this file is located on mac osx here
# ~/.ackrc 

# Always sort the files
#--sort−files

# Always color, even if piping to a another program
--color

# Use "less −r" as my pager
# --pager
# less -r

#make sure ack knows how to search common filetypes used in rails projects
--type-add=css=scss

@F1LT3R --sort-files should work just fine. If you still can't get it working, please submit a ticket here: https://github.com/petdance/ack2
