Full Discussion: Array compare bash script

IFS includes a newline, so you do not need xargs to convert newline to a space character.
My script sample needs a sorted input.
For example
Code:
ARRAY2=($(df -Pk | awk '$6~/^[/]/{print$6}' | sort)) # df
ARRAY=($(awk '/^[^#]/ && $2~/[/]/ && $3!~/devpts|sysfs|proc/{print $2}' /etc/fstab | sort)) # fstab

BTW df does unneeded stat() and statfs(), a mount -v would be less overhead.

Please avoid unneeded cat! If you want to have /etc/fstab first in the line then do
Code:
ARRAY=($( </etc/fstab awk '/^[^#]/ && $2~/[/]/ && $3!~/devpts|sysfs|proc/{print $2}' | sort)) # fstab

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.
