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

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
