(OP)

why the last test doesn't work? expected is true because B=b

CODE

$ A=a
$ B=b
$ C=c
$ [ $A = "a" -a $B = "b" -a $C = "c" ] && echo true || echo false
true
$ [ $A = "a" -a $B = "b" -a $C = "b" ] && echo true || echo false
false
$ [ $A = "a" -a [ $B = "b" -o $C = "b" ] ] && echo true || echo false
ksh: b: 0403-012 A test command parameter is not valid.
false
$

Hi

The [ is shell builtin function, you can not use it like that. The closest would be :

CODE

[ $A = "a" -a \( $B = "b" -o $C = "b" \) ] && echo true || echo false 
Tested with mksh.
