Repeat printf arguments with command line operator

问题:

I want to repeat the same argument $i for the instances 03-12. I'm really trying to use some nco operators - but the printf statement is hanging me up. I'm trying to use an netcdf operator on it - where these outputs of the printf are the input files to the command. While this works now with the printf statements, it's not piping into the netcdf command. Which goes as: ncea -v T,U inputfiles outputfile

#!/bin/csh                                                                                                                                                                                                                                             
set i = 1
while ($i < 2)
    ncea -v T,U
    foreach j ( {3,4,6,7,8,9,10,11,12} )
        `printf O3_BDBP_1979ghg.cam.h0.00%02d-%02d.nc $j $i `
    end

    O3_BDBP_1979.nc
    @ i = $i + 1
end

Other printf statements I've tried are

ncea -v T,U `printf O3_BDBP_1979ghg.cam.h0.00{03,04,05,06,07,08,09,10,11,12}-%02d.nc $i` O3_BDBP_1979.nc
ncea -v T,U `printf O3_BDBP_1979ghg.cam.h0.00{03,04,05,06,07,08,09,10,11,12}-%1$02d.nc $i` O3_BDBP_1979.nc
