Error in RQ createcontent command

Hello Community,

I have one doubt in RQ command.

I tried "RQ createcontent" command in command line with the below syntax but it shows error.

""RQ createcontent --type=ALM_specification --parentID=3654306 --richContentField='ALM_Text=sample' --addRelationships="Validated By:"3491362(I found the error in --addRelationships)""

could you please tell me how to execute this command properly.
