EXAMPLES
A file called "aa.hdf" contains three items associated with a raster image; the image dimensions, a palette, and the raster image. To display information about the contents of this file, the following command is used.hdfls aa.hdf
The following output is displayed:
aa.hdf: Image Dimensions-8: (Raster-8): (tag 200) Ref nos: 1 Image Palette-8: (Raster-8): (tag 201) Ref nos: 3 Raster Image-8: (Raster-8): (tag 202) Ref nos: 1The following displays the same information with the length of each data element:
hdfls -l aa.hdf
This would result in the following information being displayed:
aa.hdf: Image Dimensions-8: (Raster-8) : (tag 200) Ref no 1 4 bytes Image Palette-8: (Raster-8) : (tag 201) Ref no 3 768 bytes Raster Image-8: (Raster-8) : (tag 202) Ref no 1 120000 bytes
