DESCRIPTION

       t.list  lists any dataset that is registered in the temporal database. Datasets are raster, 3D raster and
       vector maps as well as their corresponding space time datasets (STRDS, STR3DS and STVDS). The type of the
       dataset  can  be specified using the type option, default is STRDS. By default all datasets with relative
       and absolute time are listed. However, the user has the ability to specify a single  temporal  type  with
       the  temporaltype option. The user can define the columns that should be printed for each dataset and the
       order of the datasets. In addition a SQL WHERE statement can be specified  to  select  a  subset  of  the
       requested datasets.

NOTES

       The SQL where and sort expression will be applied for each temporal database that was found in accessible
       mapsets. Hence sorting works only on mapset basis.

       Temporal databases stored in other mapsets can be used as long as they are in the user’s  current  mapset
       search path (managed with g.mapsets).

EXAMPLES

       Obtain the list of space time raster dataset(s):
       t.list strds
       ----------------------------------------------
       Space time raster datasets with absolute time available in mapset <climate_2000_2012>:
       tempmean_monthly@climate_2000_2012
       Obtain  the  list of space time raster datasets in a specific mapset (Note that the target mapset must be
       in the user’s search path):
       # strds in PERMANENT
       t.list strds where="mapset = ’PERMANENT’"
       ----------------------------------------------
       # strds in climate_2000_2012
       t.list strds where="mapset = ’climate_2000_2012’"
       ----------------------------------------------
       Space time raster datasets with absolute time available in mapset <climate_2000_2012>:
       precip_abs@climate_2000_2012
       precipitation@climate_2000_2012
       tempmean@climate_2000_2012
       The where option can also be used to list the stds with a certain pattern in  their  name,  i.e.  as  the
       pattern option in g.list.
       # strds whose name start with "precip"
       t.list type=strds where="name LIKE ’precip%’"
       ----------------------------------------------
       Space time raster datasets with absolute time available in mapset <climate_1970_2012>:
       precip_abs@climate_1970_2012
       precipitation@climate_1970_2012
       The user can also obtain the list of time stamped raster maps. These maps might be registered in strds or
       not. The output of the following command can vary according to the accessible mapsets  specified  through
       g.mapsets.
       t.list raster
       Time stamped raster maps with absolute time available in mapset <climate_2000_2012>:
       2009_01_tempmean@climate_2000_2012
       2009_02_tempmean@climate_2000_2012
       2009_03_tempmean@climate_2000_2012
       ...
       2012_10_tempmean@climate_2000_2012
       2012_11_tempmean@climate_2000_2012
       2012_12_tempmean@climate_2000_2012
