<-p 0> is not a valid option usage: h5diff [OPTIONS] file1 file2 [obj1[obj2]] file1 File name of the first HDF5 file file2 File name of the second HDF5 file [obj1] Name of an HDF5 object, in absolute path [obj2] Name of an HDF5 object, in absolute path OPTIONS -h, --help Print a usage message and exit -V, --version Print version number and exit -r, --report Report mode. Print differences -v, --verbose Verbose mode. Print differences, list of objects -q, --quiet Quiet mode. Do not do output -c, --compare List objects that are not comparable -N, --nan Avoid NaNs detection -n C, --count=C Print differences up to C number -d D, --delta=D Print difference when greater than limit D -p R, --relative=R Print difference when greater than relative limit R C - is a positive integer D - is a positive number. Compare criteria is |a - b| > D R - is a positive number. Compare criteria is |(b-a)/a| > R Modes of output: Default mode: print the number of differences found and where they occured -r Report mode: print the above plus the differences -v Verbose mode: print the above plus a list of objects and warnings -q Quiet mode: do not print output Compare criteria If no objects [obj1[obj2]] are specified, h5diff only compares objects with the same absolute path in both files The compare criteria is: 1) datasets: numerical array differences 2) groups: name string difference 3) datatypes: the return value of H5Tequal 2) links: name string difference of the linked value Return exit code: 1 if differences found, 0 if no differences, 2 if error Examples of use: 1) h5diff file1 file2 /g1/dset1 /g1/dset2 Compares object '/g1/dset1' in file1 with '/g1/dset2' in file2 2) h5diff file1 file2 /g1/dset1 Compares object '/g1/dset1' in both files 3) h5diff file1 file2 Compares all objects in both files Note) file1 and file2 can be the same file. Use h5diff file1 file1 /g1/dset1 /g1/dset2 to compare '/g1/dset1' and '/g1/dset2' in the same file
