I created this script that basically will email me whenever anyone installs a thumbdrive, external HD, etc. in one of the servers. But I can't get the thing to work it always emails BAD. I have copied from the screen or from the HD.txt file and neither work.

Thanks to all in advance.

=========================

lsblk -io KNAME,TYPE,SIZE,MODEL > HD.txt ## gets all HDs & partitions in system
sed -i -r 's/\s+//g' HD.txt ## removes whitespace
sed -i ':a;N;$!ba;s/\n/XX/g' HD.txt ## remove carriage returns and replaces with XX

# Edit HD.txt to insert in the value below
PARTITIONS1="KNAMETYPESIZEMNODEL?sdadisk149.1GST3160318AS?sda1part500M?sda2part27.5G?dm-0crypt27.5G?dm-1lvm25.5G?dm-2lvm2G?sr0rom1024MDVDCDH48C2S"
PARTITIONS2=$(cat HD.txt)

if [[ $PARTITIONS1 == $PARTITIONS2 ]]
then
echo "Good"
else
echo "BAD on `hostname`" |mail -s "BAD on `hostname`" root &
fi

change the script so that it outputs the 2 variables, and compare them manually.
also i'm pretty sure you have to put doublequotes around them (and some other places in the script).

Sorry but I really am not much of a programmer, can I bug you to show me? I tried the double quotes.. no luck.

This script works great on one liners in the first variable without the the need for SED. I have about 10 such like scripts that do mediocre jobs.

I am guessing there is something line return or such in missing; something my eyes can not see.

thanks for the help.

Is there an "almost equal" coding or this is "contained inside"?

SOLVED... typos on my part here is a debug version edit to your own taste.

echo "put your coding in here to destroy (shred, wipe, etc) USB or HD or whatever someone is using in your server to steal your stuff. NOTE in GRUB if you are not on a server with a USB keyboard put in "nousb" at the end of the kernel line so no usb anything works."

# rm HD.txt

users on a server...I can't get over that practice. I'm just sayin'...

Not legit users, if you get the idea. I am sure you can adopt this for any workstation too.

I have often thought virtual Winblows in a Linux and no one leaves with company materials.
