KEYWORDS

general, map management

SYNOPSIS

g.xlist
g.xlist help
g.xlist [-rtmpf] type=datatype[,datatype,...] [pattern=string] [separator=string] [mapset=string] [--verbose] [--quiet]

Flags:

-r
Use extended regular expressions instead of wildcards
-t
Print data types
-m
Print mapset names
-p
Pretty printing in human readable format
-f
Verbose listing (also list map titles)
--verbose
Verbose module output
--quiet
Quiet module output

Parameters:

type=datatype[,datatype,...]
Data type
Options: rast,rast3d,vect,oldvect,asciivect,icon,labels,sites,region,region3d,group,3dview,all
Default: rast
pattern=string
Map name search pattern (default: all)
Default: *
separator=string
One-character output separator, newline, space, or tab
Default: newline
mapset=string
Mapset to list (default: current search path)

DESCRIPTION

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

EXAMPLES

List all available GRASS data base files:
  g.xlist type=all
List all raster and vector maps:
  g.xlist type=rast,vect

Wildcards:

List all vector maps starting with letter "r":
  g.xlist type=vect pattern="r*"
List certain raster maps with one variable character/number:
  g.xlist type=rast pattern="N45E00?.meters"

Regular expressions:

Print out all soils map with "soils" in their name:
  g.xlist -r type=rast pattern='^soils'
Print out "tmp" if "tmp" raster map exists:
  g.xlist -r pattern='^tmp$'
Print out "tmp0" ..."tmp9" if corresponding vector map exists (each map name linewise):
  g.xlist -r type=vect pattern='^tmp[0-9]$'
Print out "tmp0" ..."tmp9" if corresponding vector map exists (each map name comma separated):
  g.xlist -r type=vect separator=, pattern='^tmp[0-9]$'
This may be useful for other programs' parameter input (e.g. r.series).
