.TH DHCP 1
|
||||
.SH NAME
|
||||
dhcp - obtain network configuration via DHCP
|
||||
|
||||
.SH SYNOPSIS
|
||||
dhcp
|
||||
|
||||
.SH DESCRIPTION
|
||||
The DHCP client automatically obtains an IP address, subnet mask,
|
||||
default gateway, and other network parameters from a DHCP server
|
||||
on the local network using the Dynamic Host Configuration Protocol
|
||||
(RFC 2131).
|
||||
|
||||
On success the network configuration is applied immediately via
|
||||
set_netcfg(). On failure the original configuration is restored.
|
||||
|
||||
The client is run automatically by the init system at boot, but
|
||||
may also be invoked manually from the shell.
|
||||
|
||||
.SH PROTOCOL
|
||||
The client performs the standard four-message DHCP exchange:
|
||||
|
||||
1. DHCPDISCOVER Broadcast to 255.255.255.255:67
|
||||
2. DHCPOFFER Server offers an IP address
|
||||
3. DHCPREQUEST Client accepts the offered address
|
||||
4. DHCPACK Server confirms the lease
|
||||
|
||||
The BROADCAST flag (0x8000) is set so that server replies are
|
||||
sent to the broadcast address, since the client has no IP yet.
|
||||
|
||||
Each step has a 10-second timeout. If no response is received
|
||||
the client exits with an error and restores the previous config.
|
||||
|
||||
.SH OUTPUT
|
||||
On success the client prints the assigned configuration:
|
||||
|
||||
IP Address, Subnet Mask, Gateway, DNS Server, Lease Time
|
||||
|
||||
.SH OPTIONS
|
||||
The DHCP client requests the following options from the server:
|
||||
|
||||
1 Subnet Mask
|
||||
3 Router (default gateway)
|
||||
6 DNS Server
|
||||
51 Lease Time

|
||||
edit - text editor for ZenithOS
|
||||
|
||||
.SH SYNOPSIS
|
||||
edit [filename]
|
||||
|
||||
.SH DESCRIPTION
|
||||
edit is an interactive text editor. When invoked with a filename,
|
||||
it opens the file for editing. If the file does not exist, a new
|
||||
empty buffer is created and will be saved to that path on write.
|
||||
|
||||
When invoked without arguments, edit opens an empty buffer. You
|
||||
will be prompted for a filename when saving.

.SH DISPLAY
|

The top line shows the filename, a modified indicator [+],
|
||||
and the current cursor position (Ln, Col).
|
||||
|

The bottom line shows keyboard shortcuts or status messages.

.TH INIT 1
|
||||
.SH NAME
|
||||
init - ZenithOS init system
|
||||
|
||||
.SH SYNOPSIS
|
||||
Spawned automatically by the kernel as PID 0.
|
||||
|
||||
.SH DESCRIPTION
|
||||
init is the first userspace process started by the ZenithOS
|
||||
kernel. It chains system services in sequence, then launches
|
||||
the interactive shell.
|
||||
|
||||
Each service is spawned as a child process. init waits for it
|
||||
to exit before starting the next one. If a service fails to
|
||||
spawn, init logs an error and continues to the next stage.
|
||||
|
||||
Log output is timestamped and color-coded:
|
||||
|
||||
HH:MM:SS INFO init Starting dhcp
|
||||
HH:MM:SS OK init dhcp finished (pid 1)
|
||||
|
||||
.SH BOOT SEQUENCE
|
||||
The following services are started in order:
|
||||
|
||||
1. 0:/os/dhcp.elf Obtain network configuration via DHCP
|
||||
2. 0:/os/shell.elf Launch the interactive shell
|
||||
|
||||
After the shell exits, init enters an idle loop.
|
||||
|
||||
.SH LOG LEVELS
|
||||
init uses four log levels, each with a distinct color:
|
||||
|
||||
OK Green Service completed successfully
|
||||
INFO Cyan Informational (service starting, etc.)
|
||||
WARN Yellow Non-fatal warning
|
||||
FAIL Red Service failed to start

|
||||
the first userspace process. It provides basic file inspection,
|
||||
process management, networking, and documentation access.
|
||||
The ZenithOS shell is a command interpreter launched by init
|
||||
after system services have started. It provides command
|
||||
execution, file navigation, and command history.
|
||||
|
||||
.SH COMMANDS
|
||||
Commands are either shell builtins or external programs. When
|
||||
a command is not a builtin, the shell searches for a matching
|
||||
ELF binary and executes it as a child process.
|
||||
|
||||
.SH COMMAND RESOLUTION
|
||||
When a non-builtin command is entered, the shell searches for
|
||||
a matching binary in the following order:
|
||||
|
||||
1. 0:/os/<command>.elf
|
||||
2. 0:/games/<command>.elf
|
||||
3. 0:/<cwd>/<command>.elf (if cwd is set)
|
||||
4. 0:/<command>.elf
|
||||
|
||||
The first match is spawned and the shell waits for it to exit.
|
||||
If no match is found, the shell prints:
|
||||
|
||||
<command>: command not found
|
||||
|
||||
Arguments after the command name are passed to the spawned
|
||||
process. File path arguments are resolved against the current
|
||||
working directory before being passed to external programs.
|
||||
|
||||
.SH BUILTINS
|
||||
|
||||
.SS help
|
||||
Display a list of available commands.
|
||||
|
||||
.SS info
|
||||
Show the OS name, version, and syscall API version number.
|
||||

||||
.SS man <topic>
|
||||
Open a manual page in the fullscreen pager. See man(1).
|
||||
Display a categorized list of available commands.
|
||||
|
||||
.SS ls [dir]
|
||||
List files in the current directory, or in the specified
|
||||
directory. When a directory argument is given, the output
|
||||
shows only the entries inside that directory with the
|
||||
directory prefix stripped.
|
||||
Examples: ls, ls man
|
||||
directory prefix stripped. Directory entries are shown
|
||||
with a trailing slash.
|
||||
Examples: ls, ls man, ls os
|
||||
|
||||
.SS cd [dir]
|
||||
Change the working directory. With no argument or with /,
|
||||
returns to the root (0:/). Use cd .. to go up one level.
|
||||
Trailing slashes on directory names are stripped.
|
||||
The shell prompt reflects the current directory.
|
||||
Examples: cd man, cd .., cd
|
||||
|
||||
.SS cat <file>
|
||||
Print the contents of a file to the terminal. The file
|
||||
path is resolved relative to the current directory.
|
||||
Example: cat hello.elf
|
||||
|
||||
.SS run <file>
|
||||
Spawn a new process from an ELF binary and wait for it to
|
||||
exit. The file path is resolved relative to the current
|
||||
directory. The shell blocks until the child process terminates.
|
||||
Example: run hello.elf
|
||||
|
||||
.SS ping <ip>
|
||||
Send 4 ICMP echo requests to the given IP address and display
|
||||
round-trip times. Timeout is 3 seconds per request.
|
||||
Example: ping 10.0.2.2
|
||||
|
||||
.SS date
|
||||
Display the current date and time in UTC.
|
||||
|
||||
.SS uptime
|
||||
Display the system uptime in minutes, seconds, and milliseconds.
|
||||
|
||||
.SS clear
|
||||
Clear the terminal screen.
|
||||
Examples: cd os, cd .., cd
|
||||
|
||||
.SS exit
|
||||
Terminate the shell process.

Backspace is supported. Lines are limited to 255 characters.
|

There is no command history or tab completion.
|
