I am currently working on setting up a shell script to monitor NAS backup disk space for your account. I am completely new to scripting and linux itself so bare with me lol.

NAS Backup Server Disk Monitoring Shell Script
LIMIT="17" - is it suppose to be how much space left?
GETNASIP=$(host ${NASIP} | awk '{ print $4}') - Does host get replace
by the IP address? Or what is the purpose of this line?

I also am confused with the following:

Do I choose between the two options or am I required to have both to make this script work. I can no longer find the edit button in the forums, so I am sorry that I am double posting.

# Failsafe[ ! -d ${NASMNTPOINT} ] && mkdir -p ${NASMNTPOINT}mount | grep //${GETNASIP}/${NASUSER}
or

# if not mounted, just mount nas[ $? -eq 0 ] && : || mount -t cifs //${NASIP}/${NASUSER} -o username=${NASUSER},password=${NASPASS} ${NASMNTPOINT}cd ${NASMNTPOINT}
???

Yes, this is warning level. If 17GB space is occupied it will send an email.

It will get nas server IP address i.e. it will convert nas.example.com to its IP address.

You only need to set the following:
NASUSER="Your-User-Name"
NASPASS="Your-Password"
NASIP="nas.yourcorp.com"
NASROOT="/username"
NASMNTPOINT="/mnt/nas"
EMAILID="admin@yourcorp.com"

Rest will work out automatically. There is no need to modify the rest of script untie and unless you have a specific needs.

thank you for being so helpful.

I may of found an error in the script.
I modified the NASROOT=/home, but I noticed that this variable is not being used in the script. I might of found a place that it might be used which is when the cd ${NASMNTPOINT}. Am I right?
