[GRASS-user] How to obtain list of all raster maps

[BHARATH RAM]

Dear Mr. Neteler & Mr. Silver,

    Thank you both for your responses. Yes both of the methods seems to be
working.

Also, while going through some other documentation i discovered another
metho. We can output the entire data into a text file by including an
output argument in the command. (*g.list type='raster' mapset='.'
output='rasterNames.txt' )*

Problem solved... Thanks

Regards,
Bharath
