The following line:

db.foo.runCommand( name , <options> ) runs a db command with the given name where the 1st param is the colleciton name

should be:

db.foo.runCommand( name , <options> ) runs a db command with the given name where the 1st param is the collection name

or, to be consistent with the rest of the help information:

db.foo.runCommand( name , <options> ) runs a db command with the given name where the first parameter is the collection name
