which user uses maximum disk space

[Shivkumar]

Dear Sirs/Madam;

I want to find out which user is using maximum disk space in /home directory file system.

Can anyone tell which command i should use ?

Thanks,
Shiv

cd to /home directory and run
du -ks *
This will show you the sizes of each directory (which is users home directory) with their sizes in KB

[Ermin Borovac]

If directory is root of the filesystem you can use quot(1M).

# /usr/sbin/quot /home

It will produce disk usage in KB for each user sorted with top users first.

Hi,
Try run this:
#du -akx /home|sort -nr|more
This wiil sort from largest to lowest used space under /home dir.

Hi,

quot is the best way to find out this. Allthough all of the above solutions works to some extent.

But apparently it seems your /home is the only worry for you at this time as you are posting several questions related to this at present. Could you attach "bdf" output and "vgdisplay -v vg00" output.

HTH,
Devender

Shiv,

i often use to determine max using /home
users and warn them like;

cd /home;
du -ks * |sort -n

and if i want to warn them to delete their
unnecessary files then;

#!/usr/bin/ksh
cd /home;
if [ $? -ne 0 ]
then
echo "/home not found..."
exit 1
fi
for user in `du -ks * |sort -n|tail -10|awk '{print $2}'`
do
echo "Please clean your unnecessary files!!!Contact Shivkumar"|mailx -s "home dir usage" $user@mail_address
done

Above the script;last 10 top disk usage users
will be inform via e-mail

Good Luck,

You can use script like,

#!/bin/ksh

total=$(find /home/ -user root | xargs ls -l | awk 'BEGIN {size=0;}{size+=$5;}END{print size;}')
echo "root user is using $total size in /home"
for user in `ls /home/ | grep -v 'lost+found'`
do
id $user 1>/dev/null 2>&1
if [[ $? -eq 0 ]]
then
total=$(find /home/ -user $user | xargs ls -l | awk 'BEGIN {size=0;}{size+=$5;}END{print size;}')
echo "$user is using $total size in /home"
fi
done

hth.
