Hi Klaus,
the [..] operator is used to convert generic numerical value (maybe
result of arithmetic ops to logical value.
in your example, the == is already a logical operator, so no need to any
conversion.

Hi!
from the core cookbook of 1.2:
If you want to evaluate arithmetic operations and
test the value in
conditions, use the test operator ' [ ... ] ' . This is required to
convert the result to internal convention for drop, true and false.
if ( [ $var(a)&4 ] ) {
xlog("bit 3 is set in var a");
}
Is there somewhere a detailed description of the test operator? Can it
only be used to test for 0/1 or can I also do comparison like e.g.
if ([ $rd == "mydomain.at" ]) ?
regards
klaus
