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
