Array compare bash script

Hello,

i have a script that should compare between ${ARRAY[@]}
that contains all fstab record like this :
Code:
>>echo ${ARRAY[@]}
/ /boot

between all mountpoints in my df that is stord in ${ARRAY2[@]}
Code:
>>echo ${ARRAY2[@]}
/ /boot /dev/shm /var/spool/asterisk/monitor

now i have this loop:
Code:
for i in ${ARRAY[@]}; do
	for j in ${ARRAY2[@]}; do
	if [[ $i != $j ]];then
		echo "fstab $i doesnt exsist in $j df"
		exit 
		fi
		done
	done

what happend now is that for exsample ${ARRAY[@]} try to compare first value "/" to all values in ${ARRAY2[@]} like this :

Code:
[ / != / ]]
[[ / != /boot ]]

and then the script fails - my point here is to find if i have records in fstab
that are not mounted on df

i want that when ${ARRAY[@]} found a match in ${ARRAY2[@]}
it will continue to next value and not try to match the first value to all ${ARRAY2[@]} values.

thanks

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME
atf-sh [-s shell] -- interpreter for shell-based test programs SYNOPSIS
atf-sh script DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library. atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter- preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not use any non-standard extensions. The following options are available: -s shell Specifies the shell to use instead of the value provided by ATF_SHELL. ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes. ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes. ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a specific interpreter. EXAMPLES
Scripts using atf-sh(3) should start with: #! /usr/bin/env atf-sh Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode the path to atf-sh in the script and then use the -s option afterwards as a single parameter: #! /path/to/bin/atf-sh -s/bin/bash ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts. SEE ALSO
