Note: A new GRASS GIS stable version has been released: GRASS GIS 7. Go directly to the new manual page here

NAME

g.mlist - Lists available GRASS data base files of the user-specified data type optionally using the search pattern.

KEYWORDS

general, map management

SYNOPSIS

g.mlist
g.mlist help
g.mlist [-retmpf] type=datatype[,datatype,...] [pattern=string] [exclude=string] [separator=string] [mapset=string] [--verbose] [--quiet]

Flags:

-r: Use basic regular expressions instead of wildcards
-e: Use extended regular expressions instead of wildcards
-t: Print data types
-m: Print fully-qualified map names (including mapsets)
-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)
exclude=string: Map name exclusion pattern (default: none)
separator=string: One-character output separator, newline, comma, space, or tab; Default: newline
mapset=string: Mapset to list (default: current search path)

DESCRIPTION

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

EXAMPLES

List all available GRASS data base files:

  g.mlist type=all

List all raster and vector maps:

  g.mlist type=rast,vect

Wildcards:

List all vector maps starting with letter "r":

  g.mlist type=vect pattern="r*"

List certain raster maps with one variable character/number:

  g.mlist type=rast pattern="N45E00?.meters"

Use of exclude parameter:

# without exclude:
g.mlist rast pat="r*" mapset=PERMANENT
railroads
roads
rstrct.areas
rushmore

# exclude only complete word(s):
g.mlist rast pat="r*" exclude=roads mapset=PERMANENT
railroads
rstrct.areas
rushmore

# exclude with wildcard:
g.mlist rast pat="r*" exclude="*roads*" mapset=PERMANENT
rstrct.areas
rushmore

Regular expressions:

Print out all soils map with "soils" in their name:

g.mlist -r type=rast pattern='^soils'

Print out "tmp" if "tmp" raster map exists:

  g.mlist -r pattern='^tmp$'

Print out "tmp0" ..."tmp9" if corresponding vector map exists (each map name linewise):

  g.mlist -r type=vect pattern='^tmp[0-9]$'

Print out "tmp0" ..."tmp9" if corresponding vector map exists (each map name comma separated):

  g.mlist -r type=vect separator=, pattern='^tmp[0-9]$'

This may be useful for other programs' parameter input (e.g. r.series).
