 595 <div class="paragraph"><p>Displays references available in a local repository along with the associated

 597 dereferenced into object IDs. Additionally, it can be used to test whether a

 690         and performs the following actions on each:
 691         (1) strip "</sup>{}" at the end of line if any;
 692         (2) ignore if pattern is provided and does not head-match refname;
 693         (3) warn if refname is not a well-formed refname and skip;
 694         (4) ignore if refname is a ref that exists in the local repository;
