NAME

g.mlist - Lists available GRASS data base files of the user-specified data type to standard output.

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 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)

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).
