A term enclosed with [...] is optional, - and may not be required by all forms of the command. - - Some commands may not be availalble. Use the '?' command to list - most available commands. - -################################################################################ -# Tautoboot DBoot after a delay - - autoboot [<delay> [<prompt>]] - - Displays <prompt> or a default prompt, and counts down <delay> seconds - before attempting to boot. If <delay> is not specified, the default - value is 10. - -################################################################################ -# Tboot DBoot immediately - - boot [-<arg> ...] [<kernelname>] - - Boot the system. If arguments are specified, they are added to the - arguments for the kernel. If <kernelname> is specified, and a kernel - has not already been loaded, it will be booted instead of the default - kernel. - -################################################################################ -# Techo DEcho arguments - - echo [-n] [<message>] - - Emits <message>, with no trailing newline if -n is specified. This is - most useful in conjunction with scripts and the '@' line prefix. - - Variables are substituted by prefixing them with $, eg. - - echo Current device is $currdev - - will print the current device. - -################################################################################ -# Tload DLoad a kernel or module - - load [-t <type>] <filename> - - Loads the module contained in <filename> into memory. If no other - modules are loaded, <filename> must be a kernel or the command will - fail. - - If -t is specified, the module is loaded as raw data of <type>, for - later use by the kernel or other modules. <type> may be any string. - -################################################################################ -# Tls DList files - - ls [-l] [<path>] - - Displays a listing of files in the directory <path>, or the root - directory of the current device if <path> is not specified. - - The -l argument displays file sizes as well; the process of obtaining - file sizes on some media may be very slow. - -################################################################################ -# Tlsdev DList devices - - lsdev [-v] - - List all of the devices from which it may be possible to load modules. - If -v is specified, print more details. - -################################################################################ -# Tlsmod DList modules - - lsmod [-v] - - List loaded modules. If [-v] is specified, print more details. - -################################################################################ -# Tpnpscan DScan for PnP devices - - pnpscan [-v] - - Scan for Plug-and-Play devices. This command is normally automatically - run as part of the boot process, in order to dynamically load modules - required for system operation. - - If the -v argument is specified, details on the devices found will - be printed. - -################################################################################ -# Tset DSet a variable - - set <variable name> - set <variable name>=<value> - - The set command is used to set variables. - -################################################################################ -# Tset Sautoboot_delay DSet the default autoboot delay - - set autoboot_delay=<value> - - Sets the default delay for the autoboot command to <value> seconds. - -################################################################################ -# Tset Sbootfile DSet the default boot file set - - set bootfile=<filename>[,<filename>...] - - The default search path for bootable kernels is /kernel,/kernel.old. - It may be overridden by setting the bootfile variable to a - semicolon-separated list of paths, which will be searched for in turn. - -################################################################################ -# Tset Sboot_askname DPrompt for root device - - set boot_askname - - Instructs the kernel to prompt the user for the name of the root device - when the kernel is booted. - -################################################################################ -# Tset Sboot_ddb DDrop to the kernel debugger (DDB) - - set boot_ddb - - Instructs the kernel to start in the DDB debugger, rather than - proceeding to initialise when booted. - -################################################################################ -# Tset Sboot_gdb DSelect gdb-remote mode - - set boot_gdb - - Selects gdb-remote mode for the kernel debugger by default. - -################################################################################ -# Tset Sboot_single DStart system in single-user mode - - set boot_single - - Prevents the kernel from initiating a multi-user startup, single-user - mode will be entered when the kernel has finished device probes. - -################################################################################ -# Tset Sboot_verbose DVerbose boot messages - - set boot_verbose - - Setting this variable causes extra debugging information to be printed - by the kernel during the boot phase. - -################################################################################ -# Tset Sconsole DSet the current console - - set console[=<value>] - - Sets the current console. If <value> is omitted, a list of valid - consoles will be displayed. - -################################################################################ -# Tset Scurrdev DSet the current device - - set currdev=<device> - - Selects the default device. Syntax for devices is odd. - -################################################################################ -# Tset Smodule_path DSet the module search path - - set module_path=<path>[,<path>...] - - Sets the list of directories which will be searched in for modules - named in a load command or implicitly required by a dependancy. - -################################################################################ -# Tset Sprompt DSet the command prompt - - set prompt=<value> - - The command prompt is displayed when the loader is waiting for input. - Variable substitution is performed on the prompt. The default - prompt can be set with: - - set prompt=\$currdev> - -################################################################################ -# Tset Srootdev DSet the root filesystem - - set rootdev=<path> - - By default the value of $currdev is used to set the root filesystem - when the kernel is booted. This can be overridden by setting - $rootdev explicitly. - -################################################################################ -# Tshow DShow the values of variables - - show [<variable>] - - Displays the value of <variable>, or all variables if not specified. - Multiple paths can be separated with a semicolon. - - See the set command for a list of some variables. - -################################################################################ -# Tsource DRead commands from a script file - - source <filename> - - The entire contents of <filename> are read into memory before executing - commands, so it is safe to source a file from removable media. - - A number of modifiers may be prefixed to commands within a script file - to alter their behaviour: - - @ Suppresses the printing of the command when executed. - - - Prevents the script from terminating if the command returns - an error. - -################################################################################ -# Tread DRead input from the terminal - - read [-t <value>] [-p <prompt>] [<variable name>] - - The read command reads a line of input from the terminal. If the - -t argument is specified, it will return nothing if no input has been - received after <value> seconds. (Any keypress will cancel the - timeout). - - If -p is specified, <prompt> is printed before reading input. No - newline is emitted after the prompt. - - If a variable name is supplied, the variable is set to the value read, - less any terminating newline. - -################################################################################ -# Tunload DRemove all modules from memory - - unload - - This command removes any kernel and all loaded modules from memory. - -################################################################################ -# Tunset DUnset a variable - - unset <variable name> - - If allowed, the named variable's value is discarded and the variable - is removed. - -################################################################################ |
