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).
