Question restart case ?
simple short question...

when you make a case instruction..

read f
echo " "
case $f in
0) echo "0" ;;
1) echo "1" ;;
2) echo "2" ;;
*) echo "unknown";; # how to restart case from line 'read f' ?
esac

...just wanna get to the entry when making a false entry.
there isn't a chance of goto read f.

can anyone help ? thx..

Code:
f=0
while [ $f -ge 0 ]
do
  echo "Enter A Value: \c"
  read f
  echo " "
  case $f in 
      0)
         echo "0"
         break
         ;;
      1)
         echo "1"
         break
         ;;
      2)
         echo "2"
         break
         ;;
      *)
         echo "unknown"
         ;; 
   esac 
done

Error
thx...but it's not really working

but I've found your intention...make a while loop (infinite loop for *) and break by the others ( 1,2,3...)

...
echo "in: \c"
while read f
do
case $f in
0) echo "0"
break;;
1) echo "1"
break;;
*) echo "unknown command $f - retry"
;;
esac
done

now it's working.....cya

Huh, worked for me. Must be a difference in shell. I am using Korn on an HPUX 11.0 server
