FreeBSD Show Disk Quota Limits Command

I'm a new FreeBSD unix user and backup file on a FreeBSD based unix server. How can I check quota limits and disk usage using shell prompt on a FreeBSD based system?

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
OR
$ quota -v -h
Sample outputs:

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

Where,

1. -v : Display quotas on file systems where no storage is allocated.
2. -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 vivek@server1.cyberciti.biz quota -hv
 

I strongly suggest that you read quota man page for more information.
