knife-exec(1) -- Run user scripts using the Chef API DSL
========================================
## SYNOPSIS
__knife__ __exec__ _(options)_
* `-E`, `--exec CODE`:
Provide a snippet of code to evaluate on the command line
## 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]}'
