DESCRIPTION

       g.list searches for data files matching a pattern given by  wildcards  or  POSIX  Extended
       Regular Expressions.

NOTES

       The  output  of g.list may be useful for other programs’ parameter input (e.g. time series
       for r.series) when used with separator=comma.

EXAMPLES

       List all raster maps as continuous, sorted list:
       g.list type=rast
       List all vector maps as continuous, sorted list with MAPSET  info  (i.e.   fully-qualified
       map names):
       g.list type=vector -m
       List all raster and vector maps ordered by mapset:
       g.list type=raster -p
       List all raster and vector maps as continuous, sorted list:
       g.list type=rast,vect
       List all available GRASS data base files:
       g.list type=all

   Mapset search path
       If  mapset  is  not specified, then g.list searches for data files in the mapsets that are
       included in the search path (defined by g.mapsets).  See g.mapsets -p.
       g.list rast -p
       raster map(s) available in mapset <user1>:
       dmt
       ...
       raster map(s) available in mapset <PERMANENT>:
       aspect
       ...
       Option mapset=. (one dot) lists only data files from the current mapset:
       g.list rast mapset=.
       ...
       Similarly, mapset=* (one asterisk) prints data  files  from  all  available  mapsets  also
       including those that are not listed in the current search path (see g.mapsets -l).
       g.list rast mapset=* -p
       raster map(s) available in mapset <landsat>:
       lsat5_1987_10
       ...
       raster map(s) available in mapset <user1>:
       dmt
       ...
       raster map(s) available in mapset <PERMANENT>:
       aspect
       ...

   Wildcards
       List all vector maps starting with letter "r":
       g.list type=vector pattern="r*"
       List all vector maps starting with letter "r" or "a":
       g.list type=vector pattern="[ra]*"
       List all raster maps starting with "soil_" or "landuse_":
       g.list type=raster pattern="{soil,landuse}_*"
       List certain raster maps with one variable character/number:
       g.list type=raster pattern="N45E00?.meters"
       Use of exclude parameter:
       # without exclude:
         g.list rast pat="r*" mapset=PERMANENT
         railroads
         roads
         rstrct.areas
         rushmore
       # exclude only complete word(s):
         g.list rast pat="r*" exclude=roads mapset=PERMANENT
         railroads
         rstrct.areas
         rushmore
       # exclude with wildcard:
         g.list rast pat="r*" exclude="*roads*" mapset=PERMANENT
         rstrct.areas
         rushmore

   Regular expressions
       List all soil maps starting with "soils" in their name:
       g.list -r type=raster pattern=’^soils’
       List "tmp" if "tmp" raster map exists:
       g.list -r type=raster pattern=’^tmp$’
       List "tmp0" ..."tmp9" if corresponding vector map exists (each map name linewise):
       g.list -r type=vector pattern=’^tmp[0-9]$’
       List "tmp0"..."tmp9" if corresponding vector map exists (each map name comma separated):
       g.list -r type=vector separator=comma pattern=’^tmp[0-9]$’

   Extended regular expressions
       List all precipitation maps for the years 1997-2012, comma separated:
       g.list -e type=raster separator=comma pattern="precip_total.(199[7-9]|200[0-9]|201[0-2]).sum"

   Maps whose region overlaps with a saved region
       List  all raster maps starting with "tmp_" whose region overlaps with the region of "test"
       raster map:
       g.region raster=test save=test_region
       g.list type=raster pattern=’tmp_*’ region=test_region
       List "tmp0"..."tmp9" vector maps whose region overlaps with the current region:
       g.list -r type=vector pattern=’^tmp[0-9]$’ region=.
       List all raster and vector maps whose region overlaps  with  the  default  region  of  the
       PERMANENT mapset in the current location (DEFAULT_WIND):
       g.list type=rast,vect region=*
       Note  that,  without region=*, g.list type=rast,vect simply lists all available raster and
       vector maps from the current search path regardless of their region.
