Shell Programming and Scripting

I have a script that contains

#!/usr/bin/ksh
set -A X 'hallo' 'world'
echo ${X[0]}
echo ${X[1]}

when I execute it I get an errror message
sh ./test.ksh
./test.ksh: -A: bad option(s)

but if I do this at the command prompt I am able to create it
set -A myarray '1' '2' '3'

echo ${myarray[0]}
1

echo ${myarray[1]}
2

echo ${myarray[2]}
3

my shell is
echo `basename $0`
-ksh

why can't I create an array in my script

thanks

-A is not a valid option for the command set within sh (bourne shell).
Execute your script with Korn shell :
ksh ./test.ksh


Another solution (if your current shell is ksh) :
chmod +x ./test.ksh
./test.ksh

Thanks You da man works now

#/usr/bin/ksh
X=(hallo world)

echo ${X[0]}
echo ${X[1]}

Your script is just fine, you just start it wrong.

Instead of sh ./test.sh it shoould be only ./test.sh

The first line in the script indicates it should run in a Korn Shell
"#!/usr/bin/ksh"

When you start with the command sh ./test.sh you overrule this since you explicitly tell the script to run in a Bournse (sh) shell.

So just ./test.sh is the correct way to start it.

As indicated the x right needs to be switched on.

chmod +x test.sh
