Parameters:
type=datatype[,datatype,...] [required]
Data type(s)
Options: raster, raster_3d, vector, label, region, group, all
raster: raster map(s)
raster_3d: 3D raster map(s)
vector: vector map(s)
label: paint label file(s)
region: region definition(s)
group: imagery group(s)
all: all types
pattern=string
Map name search pattern (default: all)
exclude=string
Map name exclusion pattern (default: none)
mapset=name[,name,...]
Name of mapset to list (default: current search path)
’.’ for current mapset; ’*’ for all mapsets in location
separator=character
Field separator
Special characters: pipe, comma, space, tab, newline
Default: newline
region=name
Name of saved region for map search (default: not restricted)
’.’ for current region; ’*’ for default region
output=name
Name for output file
If not given or ’-’ then standard output
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 regard-
less of their region.
