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

Thanks you the array worked and now ur loop also.
btw - the reason i dont compare it to mount -v is cause the system thinks that the nfs is mounted but its not and only throw df i can see it :


df :
Code:
df: `/var/spool/asterisk/monitor': Stale file handle
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda2        39G  9.0G   28G  25% /
tmpfs           1.9G     0  1.9G   0% /dev/shm
/dev/sda1       283M   27M  242M  10% /boot

Code:
/dev/sda2 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/sda1 on /boot type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
192.168.223.22:/mnt/pbxarchive/PBXIL-Managment on /var/spool/asterisk/monitor type nfs (rw,vers=4,addr=192.168.223.22,clientaddr=192.168.11.100)

see that /var/spool/asterisk/monitor show like its mounted but its not also
the file looks like that :
Code:
d?????????? ? ?        ?           ?            ? monitor

and df output gives this error :
Code:
df: `/var/spool/asterisk/monitor': Stale file handle

thats why our last script that checked /proc/mounts didnt alerted us.

anyway- thank you so much for your time!

well if anyone will look it up
i have endded up doing this loop :

Code:
for i in $(</etc/fstab awk '/^[^#]/ && $2~/[/]/ && $3!~/devpts|sysfs|proc/{print $2}' | sort)
        do
        df 2> /dev/null |grep -w $i > /dev/null
                if [[ $? -ne 0 ]]
                        then
                        NOT_MOUNTED="$i $NOT_MOUNTED"
                        echo "$NOT_MOUNTED is NOT mounted!"
                        exit
                        fi
                done

Thnaks all
