This is a little snippet I shared in another thread about the LinkedIn command pack, where @Shinta_Nishino asked about extracting the last name of the recipient. Thought I'd reshare it here for posterity:
{name="Shinta Nishino"}{note: preview=no} replace this first bit with the {linkedin-name} command{endnote}
{=split(name, " ")[1]}
{=split(name, " ")[2]}
