This may seem pretty simple, but I see a lot of questions about how to get a user’s disk space usage on a cPanel user. I put together a quick list of 5 simple ways for the average admin:
1) Good ole’ cPanel/WHM. You can see the usage on the left-hand side of cPanel, or in the ‘List Accounts’ view of WHM
2) Quota cache:
egrep “^${user} ” /var/cpanel/repquota.cache
3) Actual quota:
quota -v | egrep “^${user} “
4) Manual du:
du -h /home/$user
5) cPanel datastore:
cat /home/$user/.cpanel/datastore/_usr_bin_quota_-v
