hdfls
HDFLS(1) General Commands Manual HDFLS(1)NAME
hdfls - list basic information about an HDF file
SYNOPSIS
hdfls [-o] [-l] [-d] [-v] [-g] [-s] [-h] [-t n] hdf_file
DESCRIPTION
hdfls provides general information about the tags, reference numbers, and if requested, lengths of the data elements.
OPTIONS -o display the reference numbers in ascending order.
-l long format. Display more information about the file.
-d Display offset and length information for each element in the file.
-v verbose. Display annotation and label text, along with the format triggered by the -l flag.
-g Group. List items by group.
-s Special elements. Display detailed information about special elements.
-d Display offset and length information for each element in the file.
-h Dump DD block information.
-t n Tag. Only list information about the specified tag. Must be followed by a tag number.
EXAMPLES
A file called "aa.hdf" contains three items associated with a raster image; the image dimensions, a palette, and the raster image. To dis-
play 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: 1
The 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
