Compare grib messages contained in two files. If some differences
are found it fails returning an error code. Floating point values are
compared exactly by default, different tolerance can be defined see -P -A
-R. Default behaviour: absolute error=0, bit-by-bit compare, same order in
files.
grib_compare [options] grib_file grib_file
- -r Compare files in which
the messages are not in the same order. This option is time
expensive.
- -b key,key,...
- All the keys in this list are skipped in the comparison. Bit-by-bit
compare on.
- -e Edition independent
compare. It is used to compare grib edition 1 and 2.
- -c
key[:l/d/s/n],key[:l/d/s/n],...
- Only the listed keys or namespaces (:n) are compared. The optional letter
after the colon is used to force the type in the comparison:
l->integer, d->float, s->string, n->namespace. See -a option.
Incompatible with -H option.
- -S start First field to be
processed.
- -E end Last field to be
processed.
- -a -c option modifier. The
keys listed with the option -c will be added to the list of keys compared
without -c.
- -H Compare only message
headers. Bit-by-bit compare on. Incompatible with -c option.
- -R
key1=relative_error1,key2=relative_error2,...
- Compare floating point values using the relative error as tolerance.
key1=relative_error will compare key1 using relative_error1.
all=relative_error will compare all the floating point keys using
relative_error. Default all=0.
- -A absolute error
- Compare floating point values using the absolute error as tolerance.
Default is absolute error=0
- -P Compare data values using
the packing error as tolerance.
- -T factor Compare data values
using factor multiplied by the tolerance specified in options -P -R
-A.
- -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.
