In it's simplest form, you pass it 2 numbers and it outputs a series of
lines counting from the first number to the second:

$ seq 1 10
1
2
3
4
5
6
7
8
9
10
$

Indeed. That's a printf-style format argument that says the numbers
should be padded to 6 digits with leading zeros - which seemed to be
roughly what you asked for.

Anything else you put in the -f argument will be passed through as a
string literal (e.g. the 'file' on the beginning or the '.whatever' on
the end of: 'file%06g.whatever').

However, if you want to use it in a script you could do something like:

    for file in `seq -f 'file%06g.whatever' 1 19`
    do
        echo $file
    done
