       mapset=name[,name,...]
           Name of mapset to list
           Default: current search path

       remove=name[,name,...]
           Name of file(s) to remove

       rename=from,to[,from,to,...]

       copy=from,to[,from,to,...]
           Name of file to copy

DESCRIPTION

       i.signatures module allows managing signature files:

           •   "sig" – generated by i.gensig for i.maxlik

           •   "sigset" – generated by i.gensigset for i.smap
       The  module  can  perform  multiple  actions  per  run.  The order of execution is "copy",
       "remove", "rename". When the print flag  is  specified  without  specifying  any  type  of
       signature files, it would print all signatures grouped by type.

NOTES

       By  default  the  module  will list signature files from all mapsets in the current search
       path. It is possible to limit listing only to a single mapset by  providing  the  "mapset"
       option. The mapset can be also not listed in the current search path.
       Actions  "remove"  and  "rename" operate only on the current mapset (although accept fully
       qualified names). The "copy" action will accept a signature file name from any  mapset  as
       its first argument (source file to copy).

EXAMPLES

       Print names of all signature files:
       i.signatures -p
       Print only signature files of certain type as a JSON:
       i.signatures -p type=sigset format=json
       Delete signature file called "foo" of type "sig" (i.gensig / i.maxlik).
       i.signatures remove=foo type=sig
       Copy signature file "bar" from mapset "baz" to current mapset
       i.signatures copy=bar@baz,best_version type=sigset
