help List main help categories
help category Show help for all commands in the category.
Use only the first word of the category description
help command Show help for individual command (where avaiable)
----------------------------------------------------------------------
devalias 현재 모든 디바이스 알리아스를 보여준다.
devalias alias 지정한 별명에 해당하는 디바이스 경로 이름을 보여준다.
devalias alias device-path 별명을 정의한다.
만약 같은이름이 이미 존재한다면 새로운 이름으로 대체된다.
----------------------------------------------------------------------
Diagnostic Test Commands
----------------------------------------------------------------------
probe-scsi built-in SCSI bus에 붙어있는 디바이스를 나타내준다.
test device-specifier 특별한 디바이스에 대해서 self-test 를 한다.
예를들어:
test floppy - floppy 디바이스를 테스트한다.만약있다면
test net - 네트웍연결을 테스트한다.
test-all [device-specifier] - 특별한 노드밑에있는 모든 디바이스를 테스트한다.(bulit-in self-test metod를 가지고있는) device-specifier가 존재한다면, root node가 사용되어진다.
watch-clock - 시계기능을 테스트한다.
watch-net - 네트웍 연결을 모니터한다.
----------------------------------------------------------------------
System Information Dispaly Commands
----------------------------------------------------------------------
banner power-on banner를 표시한다.
.version boot PROM의 날짜와 버전을 표시한다.
.speed CPU와 bus speed를 표시한다.
----------------------------------------------------------------------
Common Options for boot Command
----------------------------------------------------------------------
boot [device-specifier] [filename] [options]
[device-specifier] 디바이스의 이름(full path name or alias) 예를들어:
cdrom (CD-ROM drive)
disk (hard disk)
floppy (3-1/2" diskette drive)
net (Ethernet)
tape (SCSI tape)
[filename] The name of the program to be booted (for example,
stand/diag). if specified, filename is relative to the
root of the selected device and partition. if not, the
boot program uses the value of the boot-file parameter.
[options] -a - boot file의 이름과 디바이스를 대화식으로 처리
-h - Hlat after loading the program
----------------------------------------------------------------------
Emergency Keyboard Commands
----------------------------------------------------------------------
Hold down keys during power-on sequence
Stop Bypass POST. This command does not depend on security-mode
Stop-A Abort
Stop-D Enter diagnostic mode(set diag-switch? to true)
Stop-F Enter Forth on TTYA instead of probing. Use fexit to
contine with the initialization sequence.(Usefull if
hardware is broken)
Stop-N Reset NVRAM contents to default values
----------------------------------------------------------------------
.properties Display the names and values of the current node's properties
dev device-path Choose the indicated device node, making it the current
node.
dev node-name Search for a node with the given name in the subtree below
the current node, and choose the first such node found
dev .. Choose the device node that is the parent of the current
node
dev / Choose the root machine node
device-end Leave the device tree
ls Display the names of the current node's children.
pwd Display the device path name that names the current node
show-devs [device-path] Display all the devices directly under the specified device
in the device tree. show-devs used alone shows the entire
device tree
words Display the names of the current node's methods
