** Simple Question, pls help ** : Check Quota Usage for an account

I am new to Oracle, hope that you will help me to answer this easy question. Thanks.

I would like to check the usage of an oracle account. I know i can use "select * from user_ts_quotas" to check space allocated for an account, but don't know how to check how much space has already used for an oracle account. What i want is something like "quota -v" for an unix account or a file that can show the usage situation for an account.
