Script to give the disk usage in GB for each user.

Tekken · 09-08-2009, 04:09 AM

Hi,

I am trying to write a script which gives the disk usage report of every user in the server. I have wrote a code in such a way that it calculates the disk size of each user under /home and gives the output on the command line.
EX:
1GB user1
1GB user2
1GB user3
... .....
... .....
nGB usern

i am able to send this output via mail, but i want a script which can go thru each and every line, compare the size and list only the user-names who have data more than 1GB so that the same can sent thru the email. Can any one suggest me the code for the same.

Thanks...

Run as root in /home:

Code:

du -h --max-depth=1 .

Assuming the output from your first code is in input.txt in the current directory then something like

Code:

while read size user rest
do
    if [[ "${size#G*}" -gt 0 ]]; then
        echo "$user"
    fi
done < input.txt

This is not tested and is just to give you an idea of a technique to try.
