You need to use the quota command line utility to see your disk usage and limits. By default only the user quotas are printed. Disk block usage and limits are shown in 1024-byte blocks.
Checking Disk Quota on FreeBSD Server
The syntax is as follows:
quota quota -v quota [options] username quota [options] groupname
The following is sample output from my server:
$ quota -v
$ quota -v -h
Disk quotas for user vivek (uid 40142): Filesystem usage quota limit grace files quota limit grace /mnt/sales 0B 0B 0B 0 0 0 /mnt/homes 7289M 97656M 107422M 579 10000000 11000000
- -v : Display quotas on file systems where no storage is allocated.
- -h : “Human-readable” output. Use unit suffixes: Byte, Kilobyte,Megabyte, Gigabyte, Terabyte and Petabyte.
You can use the following command over ssh based session:
ssh vivek@nas01 quota -hv ssh email@example.com quota -hv
I strongly suggest that you read quota man page for more information.
