Here is a longer solution. Creating the file with ">" as Mats suggested is probably faster, but in this manner you can store the checksum into a variable in case you want to do something with it.

theFiles = file_search('XYZ_*.nc')
basename = file_basename(theFiles, '.nc')
dirname = file_dirname(theFiles)
output_filenames = filepath(basename + '.sha256', ROOT_DIR=dirname)

for i = 0, nFiles - 1 do begin
spawn, 'sha256sum ' + theFiles[i], checksum

openw, lun, output_filenames[i], /GET_LUN
printf, lun, checksum
free_lun, lun
endfor
