Execute the var(list) associated with the first var(pattern)
that matches var(word), if any. The form of the patterns
is the same as that used for filename generation. See
noderef(Filename Generation).
If the var(list) that is executed is terminated with tt(;&) rather than
tt(;;), the following list is also executed. This continues until either
a list is terminated with tt(;;) or the tt(esac) is reached.
tt(;;), the following list is also executed. The rule for
the terminator of the following list tt(;;), tt(;&) or tt(;|) is
applied unless the tt(esac) is reached.
If the var(list) that is executed is terminated with tt(;|) the
shell continues to scan the var(pattern)s looking for the next match,
executing the corresponding var(list), and applying the rule for
the corresponding terminator tt(;;), tt(;&) or tt(;|).
Note that var(word) is not re-expanded; all applicable var(pattern)s
are tested with the same var(word).
