      -r, --recursive                                      Recursively scan files/folders for datasets
      --force-recursive                                    Recursively scan folders for datasets, forcing recursion in folders recognized as valid formats
      --report-failures                                    Report failures if file type is unidentified

OPTIONS

--filename <FILENAME>
    Any file name or directory name. Required. May be repeated

-f, --of, --format, --output-format json|text
    Which output format to use. Default is JSON, or text when invoked from command line.

-r, --recursive

EXAMPLES

  Example 1: Identifying a single file

    $ gdal dataset identify NE1_50M_SR_W.tif
    NE1_50M_SR_W.tif: GTiff

  Example 2: Identifying a single file with JSON output

    $ gdal dataset identify --of=JSON NE1_50M_SR_W.tif

    [
       {
         "name": "NE1_50M_SR_W.tif",
         "driver": "GTiff"
       }
    ]

  Example 3: Recursive mode will scan subfolders and report the data format

    $ gdal dataset identify -r 50m_raster/
    NE1_50M_SR_W/ne1_50m.jpg: JPEG
    NE1_50M_SR_W/ne1_50m.png: PNG
    NE1_50M_SR_W/ne1_50m_20pct.tif: GTiff
    NE1_50M_SR_W/ne1_50m_band1.tif: GTiff
    NE1_50M_SR_W/ne1_50m_print.png: PNG
    NE1_50M_SR_W/NE1_50M_SR_W.aux: HFA
    NE1_50M_SR_W/NE1_50M_SR_W.tif: GTiff
    NE1_50M_SR_W/ne1_50m_sub.tif: GTiff
