lmatch ?mode? list pattern
              Search  the  elements  of list, returning a list of
              all elements matching pattern.  If none  match,  an
              empty list is returned.

              The mode argument indicates how the elements of the
              list are to be matched against pattern and it  must
              have one of the following values:

              -exact  The  list  element must contain exactly the
              same string as pattern.

              -glob Pattern is  a  glob-style  pattern  which  is
              matched  against  each  list element using the same
              rules as the string match command.

              -regexp Pattern is treated as a regular  expression
              and  matched  against  each  list element using the
              same rules as the regexp command.

              If mode is omitted then it defaults to -glob.
