t.remove --help
t.remove [-rf] [inputs=name[,name,...]] [type=string] [file=name]
[--help] [--verbose] [--quiet] [--ui]
Flags:

tial database
-f

Parameters:
inputs=name[,name,...]
Name of the input space time datasets
type=string
Type of the space time dataset, default is strds
Options: strds, str3ds, stvds
Default: strds
file=name
Input file with dataset names, one per line
DESCRIPTION
The module t.remove removes space time datasets (STRDS, STR3DS, STVDS)
from the temporal database. In other words, by default it deletes the
relevant database entries but not the maps.
Optionally, also the raster, 3D raster and vector maps of the space
time datasets can be removed from the current mapset using the -r (re-
cursive) and -f (force) flags. This recursive removal only works if
both flags are checked together (use -rf).
EXAMPLE
In this example a space time raster dataset (STRDS) named pre-
cip_months_sum will be created using a subset of the monthly precipita-
tion raster maps from the North Carolina climate sample data set.
In order to be able to show the case of recursive removal without
deleting the original sample data, we generate new data by means of
computing yearly precipitation sums. Eventually, all newly produced
data (STRDS and raster maps) are removed:
#Create new and empty STRDS
t.create output=precip_months_sum semantictype=mean \
title="Monthly sum of precipitation" \
description="Monthly sum of precipitation for the \
North Carolina sample data location"
#Register maps from sample dataset (selecting a subset with g.list)
t.register -i type=raster input=precip_months_sum \
maps=$(g.list type=raster pattern="201*_precip" separator=comma) \
start="2010-01-01" increment="1 months"
#Create some new data by aggregating with 1 years granularity
t.rast.aggregate input=precip_months_sum \
output=precip_years_sum basename=precip_years_sum granularity="1 \
years" method=sum
#Remove all newly produced data:
# a) the aggregated STRDS with 1 years granularity along with its raster maps
t.remove -rf type=strds input=precip_years_sum
# b) the STRDS with 1 months granularity, but not the original sample data
t.remove type=strds input=precip_months_sum
