LIGHTYENABLEMOD(1)					      General Commands Manual						LIGHTYENABLEMOD(1)

NAME
lighty-enable-mod, lighty-disable-mod - enable or disable configuration in lighttpd server SYNOPSIS
lighty-enable-mod [module] lighty-disable-mod [module] DESCRIPTION
This manual page documents briefly the lighty-enable-mod and lighty-disable-mod commands. lighty-enable-mod and lighty-disable-mod are programs that enable (and respectively disable) the specified configuration file within lighttpd configuration. Both programs can be run interactively or from command line. If either program is called without any arguments, an input prompt is dis- played to the user, where he might choose among available lighttpd modules. Immediate action is taken, if a module name was given on the command line. EXIT STATUS Both programs indicate failure in their exit status. lighty-enable-mod or lighty-disable-mod respectively may leave execution with one of the following exit codes: 0 denotes success 1 denotes a fatal error (e.g., a module could not be enabled, or a dependency was not found) 2 denotes a minor flaw (e.g., a module was not enabled because it was already loaded before) Note You can (un-) load several modules at time. The exit status will only reflect the most serious issue (where a minor flaw beats no error, but a fatal error beats a minor flaw). This means, if a minor flaw was encountered as well as a fatal error, the program will leave with exit status 1 and stop immediately. DEPENDENCIES
Debian allows lighttpd modules to formulate dependencies to other modules they depend on. Configuration files are scanned for dependencies upon load or unload of modules, not at runtime of the web server. Such a magic line has the following format: # -*- depends: module[, module] -*- and may appear anywhere in the file. If such a line is found, the extracted name is interpreted as dependency to another lighttpd module. lighty-enable-mod will seek available configurations to satisfy this dependency and will recursively enable all dependencies found on its way. lighty-disable-mod will disable reverse dependencies recursively.
