NAME

       h5diff - Compares two HDF5 files and reports the differences.

SYNOPSIS

       h5diff file1 file2 [OPTIONS] [object1 [object2 ] ]

DESCRIPTION

       h5diff is a command line tool that compares two HDF5 files, file1 and file2, and reports the differences between them.

       Optionally,  h5diff  will compare two objects within these files. If only one object, object1, is specified, h5diff will compare object1 in
       file1 with object1 in file2. In two objects, object1 and object2, are specified, h5diff will compare  object1  in  file1  with  object2	in
       file2. These objects must be HDF5 datasets.

       object1 and object2 must be expressed as absolute paths from the respective file's root group.

       Additional information, with several sample cases, can be found in the document H5diff Examples.

OPTIONS

       file1 file2
	      The HDF5 files to be compared.

       -h     Print all differences.

       -r     Print  only  the	names  of  objects that differ; do not print the differences. These objects may be HDF5 datasets, groups, or named
	      datatypes.

       -n count
	      Print difference up to count differences, then stop. count must be a positive integer.

       -d delta
	      Print only differences that are greater than the limit delta. delta must be a positive number. The comparison criterion  is  whether
	      the  absolute  value of the difference of two corresponding values is greater than delta (e.g., |a-b| > delta, where a is a value in
	      file1 and b is a value in file2).

       -p relative
	      Print only differences that are greater than a relative error. relative must be a  positive  number.  The  comparison  criterion	is
	      whether the absolute value of the difference 1 and the ratio of two corresponding values is greater than relative (e.g., |1-(b/a)| >
	      relative where a is a value in file1 and b is a value in file2).

       object1 object2
	      Specific object(s) within the files to be compared.

EXAMPLES

       The following h5diff call compares the object /a/b in file1 with the object /a/c in file2:
	   h5diff file1 file2 /a/b /a/c

       This h5diff call compares the object /a/b in file1 with the same object in file2:
	   h5diff file1 file2 /a/b

       And this h5diff call compares all objects in both files:
	   h5diff file1 file2

NAME

       diff - differential file comparator

SYNOPSIS

       diff [ -efbh ] file1 file2

DESCRIPTION

       Diff  tells what lines must be changed in two files to bring them into agreement.  If file1 (file2) is `-', the standard input is used.	If
       file1 (file2) is a directory, then a file in that directory whose file-name is the same as the file-name of file2  (file1)  is  used.   The
       normal output contains lines of these forms:

	    n1 a n3,n4
	    n1,n2 d n3
	    n1,n2 c n3,n4

       These  lines resemble ed commands to convert file1 into file2.  The numbers after the letters pertain to file2.	In fact, by exchanging `a'
       for `d' and reading backward one may ascertain equally how to convert file2 into file1.	As in ed, identical pairs where n1 = n2 or n3 = n4
       are abbreviated as a single number.

       Following  each	of these lines come all the lines that are affected in the first file flagged by `<', then all the lines that are affected
       in the second file flagged by `>'.

       The -b option causes trailing blanks (spaces and tabs) to be ignored and other strings of blanks to compare equal.

       The -e option produces a script of a, c and d commands for the editor ed, which will recreate file2 from file1.	The -f option  produces  a
       similar	script,  not useful with ed, in the opposite order.  In connection with -e, the following shell program may help maintain multiple
       versions of a file.  Only an ancestral file ($1) and a chain of version-to-version ed scripts ($2,$3,...) made by diff need be on hand.	 A
       `latest version' appears on the standard output.

	    (shift; cat $*; echo '1,$p') | ed - $1

       Except in rare circumstances, diff finds a smallest sufficient set of file differences.

       Option  -h  does  a  fast,  half-hearted job.  It works only when changed stretches are short and well separated, but does work on files of
       unlimited length.  Options -e and -f are unavailable with -h.

FILES

       /tmp/d?????
       /usr/lib/diffh for -h

SEE ALSO

       cmp(1), comm(1), ed(1)

DIAGNOSTICS

       Exit status is 0 for no differences, 1 for some, 2 for trouble.

BUGS

       Editing scripts produced under the -e or -f option are naive about creating lines consisting of a single `.'.
