NAME

       grib_compare - Compares the grib messages contained in two files.

DESCRIPTION

       Compares  the grib messages contained in two files one by one in the same order.  If some differences are
       found it fails returning an error code.  All the keys are compared except those listed with the -b option
       and those that are specific of a different grib edition. Also data values are compared and are considered
       as different if their maximum absolute difference is greater than the absolute error, that by default  is
       0.000001.  The value used by the absolute error can be set with te -e option.

USAGE

       grib_compare [options] grib_file grib_file

OPTIONS

       -b key,key,...
              Black list. All the keys in this list are skipped when comparing the two files.

              Keys to compare.  Only the listed keys are compared.

       -e tolerance

       -w key[:{s/d/l}]{=/!=}value,key[:{s/d/l}]{=/!=}value,...
              Where  clause.   Grib  messages are processed only if they match all the key/value constraints.  A
              valid constraint is of type key=value or key!=value.  For each key a string (key:s)  or  a  double
              (key:d) or a long (key:l) type can be specified. Default type is string.

       -f   Force. Force the execution not to fail on error.
