How can I parse a string with a comma thousand separator to a number?

You can override it by putting this in your application's class inside config/application.rb:

html_tag
}
Restart rails server for this change to take effect.

How can I exclude directories from grep -R?

--exclude-dir={dir1,dir2}

--exclude-dir=dir1 --exclude-dir=dir2
Quoting will prevent the shell from expanding it, so this won't work:
--exclude-dir='{dir1,dir2}' <-- this won't work
