I have a series of tasks that run one after the other, but depending on the progress, that is saved in a variable it has to start at the appropriate step.
For instance, I have 5 tasks. Task 1 is supposed to start, followed by task 2, then task 3 and so on. But if the variable progress contains the value 2, it should start at task 2, continue with task 3 and so on.
I thought this would be achievable with a switch case, like:
case $progress in
1)
echo "Task1"
$progress=2;;
2)
echo "Task2"
$progress=3;;
3)
echo "Task3";;
*)
echo "null";;
esac
The problem here is that the switch case ends, after the first match. How do I have the switch case continue after the first match?
To complement boolean.is.null's own helpful answer, here's an overview of case-branch terminators:
;; [the only option up to Bash 3.x]
case statement right away (from a matching branch).;& [Bash 4.0+]
switch statement's case handler without break. Note that unconditional means that the very next branch is entered, no matter what its condition is.;;& [Bash 4.0+]
*)), matches.;; example; outputs line one:
case 1 in
1) # entered, because it matches and is the first condition
echo 'one'
;; # exits the `case` statement here
?) # never entered
echo 'any single char.'
;;
esac
;& example (Bash 4.0+); outputs lines one and two:
case 1 in
1) # entered, because it matches and is the first condition
echo 'one'
;& # fall through to very next branch
2) # entered, because the previous branch matched and fell through
echo 'two'
;; # exits the `case` statement here
esac
;;& example (Bash 4.0+); outputs line one and any:
case 1 in
1) # entered, because it matches and is the first condition
echo 'one'
;;& # continue evaluation branch conditions
2) # not entered, because its condition doesn't match
echo 'two'
;;
*) # entered, because it's the next *matching* condition
echo 'any'
;; # using a terminator is optional in the * branch
