>Description:
test -n does not work. I always get a return code of zero, no matter if the variable has zero or more characters. I crosschecked it with the -z switch. This switch works with the same test-script.
>How-To-Repeat:
sample shell script:
--snip--
jail_interface="lala"
if [ -n ${jail_interface} ]; then
echo "interface: -$jail_interface-"
fi
--snap--
try to replace the variable jail_interface with nothing - same result. If you replace -n with -z you get the expected results.
