Hello again, I think I answered my own question. I noticed that that the dataset was correctly directed to a file when I wasn't using the compact subset form. I dug into the code a little and made the change showed in this diff. I tested that it corrected the behavior and think that this change should be pushed upstream:

Hello, I compile and package HDF5 for Cray Inc. customers, but am not as familiar with using HDF5 as I perhaps should be. A user noticed that with all versions of hdf5 equal to or greater than version 1.8.9 h5dump --ouput doesn't direct output in " DATA {} " to a file. Is this a bug with HDF5; was the functionality intentionally changed? Thanks for any help/information. Sean B. Heres the output: ~> which h5dump /opt/cray/hdf5/1.8.9/bin/h5dump seanb@guana:~/tmp> h5dump -d "IntArray[ 1, 1 ; 1, 1]" --output=test.h5.189 SDS.h5 HDF5 "SDS.h5" { DATASET "IntArray" { DATATYPE H5T_STD_I32LE DATASPACE SIMPLE { ( 5, 6 ) / ( 5, 6 ) } SUBSET { START ( 1, 1 ); STRIDE ( 1, 1 ); COUNT ( 1, 1 ); BLOCK ( 1, 1 ); DATA { (1,1): 2 } } } } ~> which h5dump /opt/cray/hdf5/1.8.8/bin/h5dump ~> h5dump -d "IntArray[ 1, 1 ; 1, 1]" --output=test.h5.188 SDS.h5 HDF5 "SDS.h5" { DATASET "IntArray" { DATATYPE H5T_STD_I32LE DATASPACE SIMPLE { ( 5, 6 ) / ( 5, 6 ) } SUBSET { START ( 1, 1 ); STRIDE ( 1, 1 ); COUNT ( 1, 1 ); BLOCK ( 1, 1 ); DATA { } } } } ~> ls -l test.h5.18* -rw-r--r-- 1 seanb criemp 14 2013-05-17 13:21 test.h5.188 -rw-r--r-- 1 seanb criemp 0 2013-05-17 13:17 test.h5.189 ~> cat test.h5.188 (1,1): 2
