[chef] knife node edit NODE from file FILE ?

[< >]

Hello,

Is there a way to replace the "attributs" of an existing node in a
non-interactive mode, using knife or another utility please ?

I can see in the documentation that there are the two following knife
sub-commands:
- node edit NODE (options) 
       Edit a node.
- node from file FILE (options)
       Create a node from a JSON file.

But my need is to 'edit' the *attributs* of an existing node 'from a file', so
a kind of merge of this two features ;)

Thanks in advance for your answers.

Best regards,
Christophe
