.SH DESCRIPTION
\fBhdiff\fR compares two HDF files and reports the
differences.
.SH OPTIONS
.TP
\*(T<\fB\-V\fR\*(T>
Display version of the HDF4 library and exit
.TP
\*(T<\fB\-b\fR\*(T>
Verbose mode
.TP
\*(T<\fB\-g\fR\*(T>
Compare global attributes only
.TP
\*(T<\fB\-s\fR\*(T>
Compare SD local attributes only
.TP
\*(T<\fB\-d\fR\*(T>
Compare SD data only
.TP
\*(T<\fB\-D\fR\*(T>
Compare Vdata data only
.TP
\*(T<\fB\-S\fR\*(T>
Print statistics
.TP
\*(T<\fB\-v\fR\*(T> \fIvar1[,...]\fR
Compare SD data on variable(s) \fIvar1\fR,...
only
.TP
\*(T<\fB\-u\fR\*(T> \fIvar1[,...]\fR
Compare vdata on variable(s) \fIvar1\fR,... only
.TP
\*(T<\fB\-e\fR\*(T> \fIcount\fR
Print difference up to count number for each variable
.TP
\*(T<\fB\-t\fR\*(T> \fIlimit\fR
Print difference when it is greater than limit
.TP
\*(T<\fB\-p\fR\*(T> \fIrelative\fR
Print difference when it is greater than a relative limit
.TP
\*(T<\fIfile1\fR\*(T>
File name of the first HDF file
.TP
\*(T<\fIfile2\fR\*(T>
File name of the second HDF file
.PP
The '\fIcount\fR' value must be a positive integer
.PP
The '\fIlimit\fR'
and '\fIrelative\fR'
values must be positive numbers
.PP
The \*(T<\fB\-t\fR\*(T> compare criteria is |a - b| > limit
.PP
The \*(T<\fB\-p\fR\*(T> compare criteria is |(b-a)/a| > relative
.PP
Return codes: 0 (no differences found), 1 (differences found)
