Exit Pig Shell

When I enter some kind of erroneous command into the interactive environment of the Pig shell, it enters listening mode (→), as shown below. How I safely leave this team, but still remain in the environment of the pig’s shell. Ctrl + C takes me out of the pig's shell, and I lose my environment setting to this point.

**grunt> Test_group = group Block2_Prep_filter by (page_visit_id as grp_page_visit_id, page_user_guid as grp_page_user_guid);
