An outer set of quotes should be "consumed" by the shell. Windows' cmd.exe only accepts double quotes. Unix shells accept either; within double quotes, most forms of substition still work, while single quotes cause everything up to the next single quote to be interpreted literally. The wxGUI command line has its own rules (see shlex.split() in the Python library documentation). Map names can be quoted with either single or double quotes, so if the expression is quoted with double quotes you can quote map names with single quotes and vice-versa. -- Glynn Clements <[email protected]> _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
