The -match_inv option prints out the inventory
which is used by the
-not_fs, -if_fs and
-sh-2.05b$ wgrib2 new.grb2 -match_inv
2:125535:d=2007032600:HGT:1000 mb:3 hour fcst:vt=2007032603
The format of the "match inventory" has evolved and will continue to evolve.
The rule for future changes is that new items in the "match inventory" will be added
as the second last item. Consequently the last item in the inventory will always
be ":vt=YYYYMMDDHH:". In order to future proof your
-match, and -not selections, you
must not include any item before the ":vt=YYYYMMDD:" field.
-match ":vt=2011111500:" good
-not ":vt=2011111500:$" good (dollar sign matches the end of the line)
-not ":n=10:vt=2011111500:" bad (item before :vt=)
-match ":RH:975 mb:anl::vt=2010050806:" bad (item before :vt=)
Some recent changes (as of Nov 2011) to the match inventory include:
- adding the "extended name of the variable", ex. TMP.prob_<273
- adding the inventory number, ex. n=10
- adding ensemble/chemical/probability information (-misc)
Changes: wgrib2 v2.0.5
For all versions of wgrib2 up to v2.0.4, the match inventory was
dependent on the verbosity mode (0,1,2). As a results, -match ":HGT:10 mb:"
would work in default mode but would not work in the -v1 and v2 modes.
With wgrib2 v2.0.5, the match inventory is generated with default
verbosity mode (-v0). It is possible that this break a few pieces
of code. However, I think that the match facility shouldn't be
dependent on the verbosity mode.
