If the month function never returns a zero-length string (and it never will in this case, AFAICS), then why not '0' instead of '00'?
You are correct, this would work.
I just got into the habit years ago that to ensure I had two characters, to always specify two.

I'm also in the same habit. It also helps a bit with "understanding" that there will be two characters always. It only costs 1 extra character, virtually no extra time even on a million rows, and makes the code more "bullet proof" (not in this case, but in most).

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Thanks wayne for the suggestion, Im just wondering, Because when I use your solution, I did not declare variable for Date. Is there a difference in performance on doing that? Or just for the purpose of readability of the codes?
declare @fn varchar(100),
@cmd varchar(200)
set @fn = 'E:\' +
right('00' + convert(varchar(2), month(DateAdd(day, -1, getdate()))), 2) +
right('00' + convert(varchar(2), day(DateAdd(day, -1, getdate()))),2) +
convert(char(4), year(DateAdd(day, -1, getdate()))) + '.Log'
SELECT @cmd = 'bcp "##LogWithNightShift" out ' + @fn + ' -f -fbcp.fmt -c -P"."'
print @cmd
--EXEC master..xp_cmdshell @cmd

You can simplify that code a bit using the date formatting in the convert function:

declare @cmd varchar(200)

select @cmd =

'bcp "##LogWithNightShift" out E:\' +

replace(convert(varchar(10),getdate()-1,101),'/','')+

'.Log -f -fbcp.fmt -c -P"."'

print @cmd

--EXEC master..xp_cmdshell @cmd

Results:

bcp "##LogWithNightShift" out E:\06282010.Log -f -fbcp.fmt -c -P"."

As a sidebar, I'd use format 112 so the file names are sortable.
