<H2>DESCRIPTION</H2>

<EM>g.mlist</EM> is an extended version of 
<EM><A HREF="g.list.html">g.list</A></EM> which
provides support for POSIX Basic Regular Expressions and wildcards.
<EM>g.mlist</EM> will only print map names and an optional separator,
without extraneous output. In addition, map search is also available.

<H2>EXAMPLES</H2>

List all available GRASS data base files:
<BR>
<TT>g.mlist type=all</TT>
<P>

List all raster and vector maps:
<BR>
<TT>g.mlist type=rast,vect</TT>
<P>

<H3>Wildcards:</H3>

List all vector maps starting with letter "r":
<BR>
<TT>g.mlist type=vect pattern="r*"</TT>
<P>

List certain raster maps with one variable character/number:
<BR>
<TT>g.mlist type=rast pattern="N45E00?.meters"</TT>

<H3>Regular expressions:</H3>

Print out all soils map with "soils" in their name:<BR>
<TT>g.mlist -r type=rast pattern='^soils'</TT>
<P>

Print out "tmp" if "tmp" raster map exists:<BR>
<TT>g.mlist -r pattern='^tmp$'</TT>
<P>

Print out "tmp0" ..."tmp9" if corresponding vector map exists (each map name linewise):<BR>
<TT>g.mlist -r type=vect pattern='^tmp[0-9]$'</TT>
<P>

Print out "tmp0" ..."tmp9" if corresponding vector map exists (each map name comma separated):<BR>
<TT>g.mlist -r type=vect separator=, pattern='^tmp[0-9]$'</TT>
<P>
This may be useful for other programs' parameter input 
(e.g. <EM><A HREF="r.series.html">r.series</A></EM>).
