DESCRIPTION
       gdal raster select can be used to select and re-order a subset of
       raster bands from a raster dataset.

       This subcommand is also available as a potential step of gdal raster
       pipeline

   Standard options

       -f, --of, --format, --output-format <OUTPUT-FORMAT>
              Which output raster format to use. Allowed values may be given
              by gdal --formats | grep raster | grep rw | sort

       --co <NAME>=<VALUE>
              Many formats have one or more optional creation options that can
              be used to control particulars about the file created. For
              instance, the GeoTIFF driver supports creation options to
              control compression, and whether the file should be tiled.

              May be repeated.

              The creation options available vary by format driver, and some
              simple formats have no creation options at all. A list of
              options supported for a format can be listed with the --formats
              command line option but the documentation for the format is the
              definitive source of information on driver creation options.
              See Raster drivers format specific documentation for legal
              creation options for each format.

       --overwrite
              Allow program to overwrite existing target file or dataset.
              Otherwise, by default, gdal errors out if the target file or
              dataset already exists.

       --band <BAND>
              Select one or several input bands. Bands are numbered from 1.
              Multiple values may be selected to select a set of input bands
              to write to the output file, or to reorder bands. The special
              value mask means the mask band of the first band of the input
              dataset. The mask band of any band can be specified with
              mask:<band>. A mask band selected with --band will become an
              ordinary band in the output dataset.

       --mask <BAND>
              Select one input band to create output dataset mask band.. Bands
              are numbered from 1.  The special value mask means the mask band
              of the first band of the input dataset. The mask band of any
              band can be specified with mask:<band>.  <BAND> can be set to
              none to avoid copying the global mask of the input dataset if it
              exists. Otherwise it is copied by default, unless the mask is an
              alpha channel, or if it is explicitly selected to be a regular
              band of the output dataset (--band mask)

GDALG OUTPUT (ON-THE-FLY / STREAMED DATASET)
       This program supports serializing the command line as a JSON file using
       the GDALG output format.  The resulting file can then be opened as a
       raster dataset using the GDALG: GDAL Streamed Algorithm driver, and
       apply the specified pipeline in a on-the-fly / streamed way.

EXAMPLES
   Example 1: Reorder a 3-band dataset with bands ordered Blue, Green, Red to
       Red, Green, Blue

          $ gdal raster select --band 3,2,1 bgr.tif rgb.tif --overwrite

   Example 2: Convert a RGBA dataset to a YCbCR JPEG compressed GeoTIFF

          $ gdal raster select --band 1,2,3 --mask 4 --co COMPRESS=JPEG,PHOTOMETRIC=YCBCR rgba.tif rgb_mask.tif
