## SYNOPSIS

## DESCRIPTION

`knife exec` runs arbitrary ruby scripts in a context similar to that of the chef-shell(1) DSL. See the chef-shell documentation for a description of the commands available.

## EXAMPLES

Make an API call against an arbitrary endpoint
  knife exec -E 'api.get("nodes/fluke.localdomain/cookbooks")' => list of cookbooks for the node fluke.localdomain
Remove the role obsolete from all nodes
  knife exec -E 'nodes.transform(:all){|n| n.run_list.delete("role[obsolete]")}'
Generate the expanded run list for hosts in the `webserver` role
  knife exec -E 'nodes.find(:roles => "webserver") {|n| n.expand!; n[:recipes]}'
