what is wrong with this script?

Hi,

I have this example script which gives error "[: ]: unexpected operator/operand". I need the '[]' brackets for operator precedence.

#!/bin/ksh
x="abc"
y="xyz"
z="123"
if [ "$x" = "abc" ] -a [ "$y" = "xyz" -o "$z" != "123" ]
then
print "yes"
else
print "no"
fi

Thanks

Do you understand that the bracket [ is not a bracket but actually a program? ( normally a link to /bin/test )

I would have thought it would be more like

Code:
if test  \( "$x" = "abc" \) -a \(  \( "$y" = "xyz" \) -o \( "$z" != "123" \) \)
then
   ....
else
   ....
fi
