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.

       -c key,key,...
              Keys to compare.  Only the listed keys are compared.

       -e tolerance
              Only values whose difference is more than tolerance are considered different.

       -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.

       -V   Version.

       -7   Does not fail when the message has wrong length

       -v   Verbose.
