Whack this in your .profile (e.g. ~/.bash_profile), re-source it ( source ~/.bash_profile ), and off you go.

Here's great rails template snippet to set up .gitignore files throughout your whole Rails project.

It ignores unnecessary files in the root .gitignore, plus it ensures no vendor/ directories are checked into git.

 
run "touch tmp/.gitignore log/.gitignore vendor/.gitignore" 
 
run %{find . -type d -empty | grep -v "vendor" | grep -v ".git" | grep -v "tmp" | xargs -I xxx touch xxx/.gitignore} 
 
file '.gitignore', <<-EOS.gsub(/^ /, '') 
.DS_Store 
log/*.log 
tmp/**/* 
config/database.yml 
config/initializers/site_keys.rb 
db/*.sqlite3
