Question disk quotas shell script


Hello.. I wrote the following shell script to run disk quotas for assigning limits to users. I need to know the partition which the user has created and mount it. So i copied the partitions (which will be displayed after running fdisk -l) and separted the last line from it and cut the required partition name from it. Then this should be passed to the next line (using mount). Here I am facing the problem.. It is returning the error "device not found", that means the variable "$part" is not giving the partition name..

The following is my code:
Code:
VSIZE=100m;

fdisk /dev/sda >/dev/null 2>&1 <<EOF
n
p
3

+${VSIZE}M
w
EOF

partprobe /dev/sda

fdisk -l > file1

awk 'NF{s=$0}END{print s}' file1 > file2

part=(`cut -c "1 2 3 4 5 6 7 8 9 10" file2`)

mkfs.ext3 $part

mkdir /var/likes

mount $part /var/likes

chmod 777 /var/likes

quotacheck -cugv /var/likes

quotaon $part

setquota -u kal 2 3 4 5 -a $part

I'd advise you to put a
Quote:
echo "$part"
line in the script to see what it is actually returning.The you can fix from there.

Quote:

cat file2 | cut
depending on what you wanna do..

Try it & see

Basically its a form of debugging; it shows you the before and after version (inc results) of parsing each line.
A key tool for fixing shell scripts.
