aregister, areg\

Show the transactions and running historical balance of a single account,
with each transaction displayed as one line.

_FLAGS

`aregister` shows the overall transactions affecting a particular account (and
any subaccounts). Each report line represents one transaction in this account.
Transactions before the report start date are always included in the running balance
(`--historical` mode is always on).

This is a more "real world", bank-like view than the [`register`](#register) 
command (which shows individual postings, possibly from multiple accounts,
not necessarily in historical mode). 
As a quick rule of thumb:
- use `aregister` for reviewing and reconciling real-world asset/liability accounts
- use `register` for reviewing detailed revenues/expenses.

`aregister` requires one argument: the account to report on.
You can write either the full account name, or a case-insensitive regular expression 
which will select the alphabetically first matched account.
(Eg if you have `assets:aaa:checking` and `assets:bbb:checking` accounts,
`hledger areg checking` would select `assets:aaa:checking`.)

Transactions involving subaccounts of this account will also be shown.
`aregister` ignores depth limits, so its final total will always match 
a balance report with similar arguments.

Any additional arguments form a [query](#queries) which will filter the
transactions shown. Note some queries will disturb the running balance,
causing it to be different from the account's real-world running balance.

An example: this shows the transactions and historical running balance
during july, in the first account whose name contains "checking":

```shell
$ hledger areg checking date:jul
```

Each `aregister` line item shows:

- the transaction's date (or the relevant posting's date if different, see below)
- the names of all the other account(s) involved in this transaction (probably abbreviated)
- the total change to this account's balance from this transaction
- the account's historical running balance after this transaction.

Transactions making a net change of zero are not shown by default;
add the `-E/--empty` flag to show them.

This command also supports the
[output destination](hledger.html#output-destination) and
[output format](hledger.html#output-format) options.
The output formats supported are `txt`, `csv`, and `json`.

### aregister and custom posting dates

Transactions whose date is outside the report period can still be
shown, if they have a posting to this account dated inside the report
period. (And in this case it's the posting date that is shown.) 
This ensures that `aregister` can show an accurate historical running
balance, matching the one shown by `register -H` with the same
arguments.

To filter strictly by transaction date instead, add the `--txn-dates`
flag. If you use this flag and some of your postings have custom
dates, it's probably best to assume the running balance is wrong.
