Bash case statement

The normally published syntax for a case statement:

case $variable in
  pattern1) statement1;;
  pattern2) statement2;;
  .
  .
  .
  *) default statement;;	# executed if no match above
esac

If the ;; operator is used, no subsequent matches are attempted after the first pattern match.
Using ;& in place of ;; causes execution to continue with the statement associated with the next pattern
Using ;;& in place of ;; causes the shell to test the next pattern if any, and execute any associated statement on a successful match
