Trying to do an Incremental Mask

[xcoder]

Hi guys,

Trying to do an incremental mask here.

I would like to do something like this: ?u?l?l?l1984

In which the first character is always an upper case and the characters in between are lower case that eventually increment via brute force mask.

In other words I want the following pattern:

?u?l?l?l1984 then...
?u?l?l?l?l1984 then...
?u?l?l?l?l?l1984
...
so forth increment with a new lowercase each time for brute force attack. How exactly can I do this under hashcat?

Thanks
