Like ledger's equity command, print a journal entry posting the total
|
|
balance of all accounts (or the specified account and its subaccounts)
|
|
in the default journal.
|
|
|
|
An entry like this is useful in the transition to a new journal file,
|
|
to zero out asset/liability balances in the old file and initialise
|
|
them in the new one. This way you get correct balances when reporting
|
|
on either file, and when including both files at once.
|
|
|
|
Usage: hledger-equity [ACCTPAT]
