Compares two journal files. It looks at the transactions of a single
account and prints out the transactions which are in one journal file but not
in the other.
Compares a particular account's transactions in two input files.
It shows any transactions to this account which are in one file but
not in the other.
This is particularly useful for reconciling existing journals with bank
statements. Many banks provide a way to export the transactions between two
given dates, which can be converted to ledger files using custom scripts or
read directly as CSV files. With the diff command you can make sure that these
transactions from bank match up exactly with the transactions in your ledger
file, and that the resulting balance is correct. (One possible concrete
workflow is to have one ledger file per year and export the transactions for
the current year, starting on January 1.)
More precisely, for each posting affecting this account in either
file, it looks for a corresponding posting in the other file which
posts the same amount to the same account (ignoring date, description,
etc.) Since postings not transactions are compared, this also works
when multiple bank transactions have been combined into a single
journal entry.
This command compares the postings of a single account (which needs to have the
same name in both files), and only checks the amount of the postings (not the
name or the date of the transactions). Postings are compared (instead of
transactions) so that you can combine multiple transactions from the bank
statement in a single transaction in the ledger file.
This is useful eg if you have downloaded an account's transactions
from your bank (eg as CSV data). When hledger and your bank disagree
about the account balance, you can compare the bank data with your
journal to find out the cause.

Examples:
```shell
$ hledger diff assets:bank:giro -f 2014.journal -f bank.journal
Unmatched transactions in the first journal:
$ hledger diff -f $LEDGER_FILE -f bank.csv assets:bank:giro
These transactions are in the first file only:
2014/01/01 Opening Balances
assets:bank:giro EUR ...

equity:opening balances EUR -...
Unmatched transactions in the second journal:
