Case statement - continue
I have a case statement. IS "continue" working in case?

Code:
 for file in ls dir/*
  
 case $file in
      a)
            do something
            continue
       ;;
       b)
            do something
            continue
       ;;
 esac

It is a Bourne shell

You're missing the "done" at the end, but yes, "continue" works properly inside case.

Example:

Code:
for X in a b c d e
do
        case "$X" in
        a) ;;
        b) ;;
        c) ;;
        d) continue ;;
        e) ;;
        esac

        echo "$X"
done

prints
Code:
a
b
c
e

...since the continue for "d" skips the echo by going straight back to the top.

I need continue after each case in

You don't need a continue after every case. You only need a continue if you want it to skip up to the top of the loop instead of running things after esac. continue is a control for the loop, not for case.

See my example.

That is what I need
Code:
 for file in ls dir/*
do
 case $file in
     a)
        do something
         continue
        ;;
     b)
        do something
         continue
        ;;
  esac
       do something else
done

Will this works?

For that, you can do:

Code:
case "$X" in
a) something ;;
b) something else ;;
*) whatever else ;;
esac
