Hi,
Attached patch (experimental) adds a new tool, grub-script-check, that can be used to check grub.cfg file syntax. Idea is to use this tool during update-grub to catch any syntax errors and reject the update. This tool uses the same parsing code as the normal mode script engine, except that it doesn't (cannot) execute any commands. Let me know your comments. As part of this tool, I found few bugs in parser.y script and is updated as necessary. Basically, current parser.y can parse only one menuentry or function command (and expects an $end after '}'), which is wrong because grub.cfg contains multiple function/menuentry definitions. This was raising a syntax error, which is fixed by modifying the gammar to support multiple menuentry/function commands. thanks, -- bvk.chaitanya
