Keep track of your piggy bank.

Every time you put coins in or take them out of your piggy bank, write here down how much did you put or take. So you won’t have to spend time counting them when you decide to take them all out.

Yes, only coins, no banknots. Well, you actually can easily add them, but table will become indeed wide.


piggybank [OPTIONS] (COINS in FILE [of CURRENCY] | COINS from FILE | show FILE [with t(ransactions)])

Common options:

  • -h,--help — print this help;
  • -v,--version — print program version;
  • -L,--list-currencies — list supported currencies and a default one;

Brief usage with examples

Put coins in

piggybank [-r | --reversed] COINS in FILE [of CURRENCY]
piggybank -r 1 4 5 4 6 8 in example.pb of SRUB

Take coins out

piggybank [-r | --reversed] COINS from FILE
piggybank -r 5 4 6 from example.pb

Show information on your piggy bank

How to put coins in

piggybank [-r | --reversed] COINS in FILE [of CURRENCY]

--reversed flag reverses the order of coins. By default they come from least significant face value to the most significant one and being complemented from left so a set shorter than number of coins in a currency, e.g. 5 8 4 will be interpreted as 0 0 0 5 8 4. And this flag will make it to be interpreted as 5 8 4 0 0 0. It is convenient if you want to add only coins of low face value (e.g. cents).

COINS is a set of coins’ counts separated with space or comma character. For example: 0 5 0 4 6 7. By default trailing zeroes will be added from the left. So if you wrote something like 6 0 5 12 then it will be complemented to 0 0 6 0 5 12 if currency has 6 coins.

FILE is a name of a piggy bank file wich may not have a .pb extension at the end, it will be added automatically.

CURRENCY specifies the currency of a new piggy bank. It will not change currency of an existing piggy bank. ISO standard is used, e.g. EUR. Case-insensitive.


piggybank 7 4 3 0 5 in example.pb of EUR
piggybank -r 0 4 6 in example

How to take coins out

piggybank [-r | --reversed] COINS from FILE

All the parameters are explained above.


piggybank -r 0 0 4 from example.pb

How to see what you have in there

piggybank show FILE [with t(ransactions)]

It will print a summary table of what is stored in a piggy bank.

with t(ransactions) will print also a table of all transactions stored in a file.


piggybank show example.pb with t


Configuration file piggybank.conf is stored in directory specified by $XDG_CONFIG_HOME environment variable or, if it isn’t set, in $HOME/.config (which is exactly where $XDG_CONFIG_HOME points to) on Linux. On Windows it is stored right in %APPDATA%.

Currently there are two options:

  • default-currency sets default currency used for new piggy banks. Its default value is SRUB.
  • currency.<ISO> defines a currency. By default there are: RUB, SRUB (has no coins of 1 and 5 kopek since they are extremely rare now), BYN, UAH, USD, EUR and GBP.

Options are simple key=value storage. Spaces between = symbol are necessary.

Currency is defined following way:


That is best described with an example. Here it is:

currency.EXM = EXM;Example;6;{}c,{}E;5,10,25,50,100,200
