[CentOS] another sed question...

Looking to change a yml file (yaml is a database type file)

*** from --- !ruby/object:Right attributes: name: Personnel Admin action: index id: "1" controller: assessments --- !ruby/object:Right attributes: name: Personnel Admin action: find id: "2" controller: assessments

*** to --- !ruby/object:Right attributes_1: name: Personnel Admin action: index id: "1" controller: assessments --- !ruby/object:Right attributes_2: name: Personnel Admin action: find id: "2" controller: assessments

where I'm taking the 'id:' field from each record and inserting an underscore and the id into the 'attributes' label directly above.

Any takers?

Thanks

Craig
