Initial Comment: In winQGIS/GRASS, this problem happens for a couple of commands (but eg r.average works, see also https://svn.qgis.org/trac/ticket/736): r.median [EMAIL PROTECTED] [EMAIL PROTECTED] output=aspect_median Illegal filename. Character <'> not allowed. ########################## Glynn Clements answered: r.median invokes r.stats via system(), using a single quote: strcpy (command, "r.stats -a '"); strcat (command, G_fully_qualified_name (basemap, base_mapset)); strcat (command, ","); strcat (command, G_fully_qualified_name (covermap, cover_mapset)); strcat (command, "'"); /* strcpy (command,"cat /tmp/t"); */ stats_fd = popen (command, "r"); sprintf (command, "r.reclass i='%s' o='%s'", G_fully_qualified_name (basemap, base_mapset), outmap); system() uses the platform's shell: /bin/sh on Unix, cmd.exe on Windows NT/2K/XP, command.com on 95/98/ME. Single quotes won't work with the Windows shells. r.average doesn't quote the map names, and uses double quotes around the output filename: sprintf (command, "%s -anC input=%s,%s fs=space > \"%s\"", STATS, basemap->answer, covermap->answer, tempfile1); Using double quotes should suffice so long as the map name doesn't contain $ or ` (a double quote would also be problematic, but isn't legal in map names). Ultimately, we need a Windows implementation of G_spawn_ex(), so that we can avoid the shell altogether. ---------------------------------------------------------------------- You can respond by visiting: http://wald.intevation.org/tracker/?func=detail&atid=204&aid=446&group_id=21 _______________________________________________ grass-dev mailing list [email protected] http://grass.itc.it/mailman/listinfo/grass-dev
