h5jam and h5unjam

Introduction

h5jam Adds user block to the front of an HDF5 file and creates a new concatenated file.
h5unjam Splits an HDF5 file into two files, one containing the user block data and the other the HDF5 data.

-i in_file.h5 Specifies the input HDF5 file.
-u in_user_file Specifies the file to be inserted into the user block. Can be any file format except an HDF5 format.
-o out_file.h5 Specifies the output HDF5 file. If not specified, the user block will be concatenated in place to the input HDF5 file.
–clobber Wipes out any existing user block before concatenating the given user block. The size of the new user block will be the larger of:
- the size of existing user block in the input HDF5 file
- the size of user block required by new input user file (size = 512 x 2N, N is positive integer.)
-h Prints a usage message and exits.
-V Prints the HDF5 library version and exits.

-i in_file.h5 Specifies the HDF5 as input. If the input HDF5 file contains no user block, exit with an error message.
-o out_file.h5 Specifies output HDF5 file without a user block. If not specified, the user block will be removed from the input HDF5 file.
-u out_user_file Specifies the output file containing the data from the user block. Cannot be used with –delete option.
–delete Remove the user block from the input HDF5 file. The content of the user block is discarded. Cannot be used with the -u option.
-h Prints a usage message and exits.
-V Prints the HDF5 library version and exits.

If neither –delete nor -u is specified, the user block from the input file will be displayed to stdout.
