artsnexthopagg − utility to aggregate nexthop table objects
in time domain


artsnexthopagg [‐v] [‐i ifIndexList] [‐I ifIndexList]
               [‐h hours] [‐o] [‐q] outfile infile(s)

artsnexthopagg is a utility that reads nexthop table objects
from ARTS files (infile(s)) and aggregates them in the time
domain, placing the resulting nexthop table object(s) into
an output file (outfile).



‐v   The ‐v option causes artsnexthopagg to print version
     information and exit immediately.

‐i ifIndexList
     The ‐i ifIndexList option may be used to select only
     data which contains an interface index attribute in
     ifIndexList.  In other words, the ‐i ifIndexList option
     lets you select data from particular interfaces or sets
     of interfaces.  ifIndexList may contain hyphens
     (indicating an inclusive range) and commas.  For
     example, ‐i 1,2,5‐8 would select data with an interface
     index attribute of 1, 2, 5, 6, 7 or 8.

‐I ifIndexList
     The ‐I ifIndexList option may be used to combine data
     which contains an interface index attribute in
     ifIndexList.  In other words, the ‐I ifIndexList option
     lets you aggregate data across a set of interfaces.
     ifIndexList may contain hyphens (indicating an
     inclusive range) and commas.  For example, ‐I 1,2,5‐8
     would combine all data with an interface index
     attribute of 1, 2, 5, 6, 7 or 8.  The resulting
     aggregate objects will contain an interface index
     attribute of 0.

‐h hours
     The ‐h hours option may be used to specify the period
     of aggregation, in hours.  The hours argument accepts a
     decimal value to permit aggregation by fractional hour
     values.  When the ‐h hours option is not used,
     artsnexthopagg will write a single nexthop table object
     for the entire time interval seen in infile(s) to
     outfile.

‐o   By default, artsnexthopagg appends to the output file,
     so you may accumlate aggregate nexthop table objects in
     a single file over multiple invocations of
     artsnexthopagg.  You may override this behavior with
     the ‐o option.  This will cause artsnexthopagg to
     overwrite the output file instead of appending to it.









                             ‐2‐


‐q   By default, artsnexthopagg prints a ’.’ for each
     nexthop table object it reads and prints a ’+’ for each
     object it writes.  You may suppress this behavior with
     the ‐q (quiet) option.
