**Bash / shell**

> You may exclude from the 10-character limit any code necessary to
> print anything.

> ... you can use up to 16 characters for your program.

**(6 chars for code + 7 chars for printing = 26 digits) = 6888888 digits**

    $ seq -s9 999999


----------
This number is bigger, but people may argue that it's in the wrong format.

> The output may be in any format (so you can print 999, 5e+100, etc.).

**(8 chars for code + 8 chars for printing = 26 digits) = more than 1183888008 digits**

    $ seq -s9 99999999

It usually takes around a minute to print the number and it contains the scientific representation of it.



----------

Some funny example:

**(10 chars = 26 digits)**

    echo $$$$$$$$$$
    2760127601276012760127601
