Korn Shell Scripting case statement help!!

wfdeng117 · 07-22-2008, 10:25 AM

I am testing the below case statement and is not working.

case ${DOWHR} in
008) << This works
echo "Test 1" ;;
[009-014]) << This does not work
echo "Test 1" ;;

esac

Please post program code in [code] tags to aid readability.

What do you expect [009-014] to match? If you expect it to match three digit numbers in the range of 9 to 14, you are mis-understanding shall pattern matching. It does not to integer ranges like that.

Probably what you want is something like this:

Code:

case "$DOWHR" in
[0-9][0-9][0-9])
        # ugly way to strip off leading 0's
        tmp="${DOWHR#0}" ; tmp="${tmp#0}"
        if [ "$tmp" -ge 9 ] && [ "$tmp" -le 14 ]; then
                echo "we have a match"
        fi
esac

Give this a try:

#!/bin/ksh

case ${DOWHR} in
008) echo "Test 1" ;;
009|010|011|012|013|014) echo "Test 2" ;;
esac

In a case/esac construct you can also specify multiple patterns to execute the same block of code, using the logical OR:

Code:

case ${DOWHR} in

   009|010|011|012|013|014) echo something ;;
  
esac

Edit: oops... too late!
