luatools --generate This is luaTeX, Version 3.141592-beta-0.10.2-2007090506 (Web2C 7.5.6) ** <I have to Control-D out here>

That is not normal. luatools --generate should not start LuaTeX at all; I now understand what happened: yesterday you reported you changed the beginning of luatools to contain: #!/bin/sh luatex --luaonly=luatools.lua "$@" That is not correct. If you want luatex to behave as a lua interpreter you have to call it with "luatex --luaonly" and no equal sign after it; simply delete that sign and replace it with a space. Or, alternatively, alter the first two lines of the script to contain "#!/usr/bin/env texlua" like originally; what is wrong with it? Arthur
