there seems a path problem with the output-file.

Replying to hellik:

r.out.xyz --verbose input=elevation@PERMANENT output=C:\wd\mg\elev.xyz          

Are you running this via the MSys shell or via cmd.exe?

The MSys shell interprets backslashes, so they need to be escaped:

r.out.xyz --verbose input=elevation@PERMANENT output=C:\\wd\\mg\\elev.xyz

or quoted:

r.out.xyz --verbose input=elevation@PERMANENT output='C:\wd\mg\elev.xyz'

In most situations, you can use a forward slash instead:

r.out.xyz --verbose input=elevation@PERMANENT output=C:/wd/mg/elev.xyz

OTOH, if you're running the command via cmd.exe (Windows' own command prompt), this would be a bug.

starting point was the wx-gui which didn't work and from which the original error message comes. then i've tried the command from the wx-gui in the msys-shell and the same error message comes up.

The MSys shell interprets backslashes, so they need to be escaped:

r.out.xyz --verbose input=elevation@PERMANENT output=C:\\wd\\mg\\elev.xyz

working in the msys-shell

or quoted:

r.out.xyz --verbose input=elevation@PERMANENT output='C:\wd\mg\elev.xyz'

working in the msys-shell

r.out.xyz --verbose input=elevation@PERMANENT output=C:/wd/mg/elev.xyz

Does this command work: (from the MSys terminal prompt)

 r.stats -1gn elevation > C:\wd\mg\elev.xyz

?

also, I seem to recall that MS Windows generally prefers you use "double" quotes for quoting. (for msys it shouldn't matter, but for a DOS-in-a-box it could)

also tested in the actual daily WinGrass-build (http://josef.fsv.cvut.cz/wingrass/grass64/) via cmd.exe which the original r.out.xyz --verbose input=elevation@PERMANENT output=C:\wd\mg\elev.xyz, but this also fails in the cmd.exe

in the msys-shell

GRASS 6.4> r.stats -1gn elevation > C:\wd\mg\elev.xyz
sh: C:wdmgelev.xyz: Permission denied

but

GRASS 6.4> r.stats -1gn elevation > "C:\wd\mg\elev.xyz"

Resolution: invalid
Status: newclosed
msys GRASS 6.4> ls C:\Temp\*
ls: C:Temp*: No such file or directory

the problem is that "\" has special meaning in a bourne shell, so when used litterally needs to be quoted. What you have done is quoted the w, m, and e characters in your filename and so the resulting string is C:wdmgelev.xyz, and apparently you don't have permission to write to your C:\ directory from that user account.

this should work without "quotes":

GRASS 6.4> r.stats -1gn elevation > C:\\wd\\mg\\elev.xyz
