|
|
.Os
|
|
.Sh NAME
|
|
.Nm user-guide
|
|
.Nd basic system usage and overview
|
|
.Sh DESCRIPTION
|
|
Sortix is a small self-hosting Unix-like operating system developed since 2011.
|
|
This document covers matters relevant to new users from other Unix-like
|
|
operating systems.
|
|
.Ss Introduction
|
|
The installation process is covered in
|
|
.Xr installation 7 .
|
|
Bootable cdrom releases will offer the options of running a live environment,
|
|
installing the operating system, or upgrading an existing installation.
|
|
.Pp
|
|
You will be presented a with standard Unix command line environment upon login or
|
|
booting the live environment.
|
|
.Ss Shutdown
|
|
.Xr init 8
|
|
spawns a session after boot.
|
|
This is
|
|
.Xr login 8
|
|
if the system is booted in multi-user mode.
|
|
This is a root shell if booted in single-user mode.
|
|
.Pp
|
|
To power off from the login screen, login as user
|
|
.Sy poweroff .
|
|
To reboot, login as user
|
|
.Sy reboot .
|
|
.Pp
|
|
To power off from a single-user boot root shell, run
|
|
.Sy exit 0
|
|
in the shell.
|
|
To reboot, run
|
|
.Sy exit 1
|
|
in the shell.
|
|
.Ss Keyboard Layout
|
|
The kernel has a default US keyboard layout compiled into it.
|
|
.Pp
|
|
You can change the current keyboard layout using
|
|
.Xr chkblayout 1 .
|
|
It loads the requested keyboard layout with the requested name from
|
|
.Pa /share/kblayout .
|
|
For instance to load a Danish keyboard layout:
|
|
.Pp
|
|
.Dl $ chkblayout dk
|
|
.Pp
|
|
The system has basic unicode capabilities but the kernel console font is limited
|
|
to characters in codepage 437.
|
|
.Ss Graphics
|
|
The bootloader prepares an appropriate video mode to the best of its abilities.
|
|
If you have a supported graphics card:
|
|
.Pp
|
|
.Bl -bullet -compact
|
|
.It
|
|
.Xr bga 4 -
|
|
Bochs Graphics Adapter found in virtual machines.
|
|
.El
|
|
.Pp
|
|
Then you can run
|
|
.Xr chvideomode 1
|
|
to change the video mode after boot.
|
|
.Pp
|
|
.Dl $ chvideomode
|
|
.Ss Manual
|
|
The system manual can be viewed with the
|
|
.Xr man 1
|
|
program.
|
|
Sortix is currently in the process of being documented and many manual pages are
|
|
missing.
|
|
The current priority is to document areas specific to Sortix and assume standard
|
|
knowledge from other operating systems.
|
|
.Ss Editor
|
|
.Xr editor 1
|
|
is the standard text file editor.
|
|
.Ss Games
|
|
The base system comes with games such as
|
|
.Xr asteroids 6 .
|
|
Additional third party games may be installed through ports.
|
|
.Ss Filesystem Hierarchy
|
|
The filesystem hierarchy is described in
|
|
.Xr hier 7 .
|
|
.Ss Memory Usage
|
|
The
|
|
.Xr memstat 1
|
|
command shows the current memory usage.
|
|
.Ss Third Party Software
|
|
Releases come with useful third party software installed.
|
|
The
|
|
.Pa /tix/installed.list
|
|
file lists all currently installed ports.
|
|
.Ss Source Code
|
|
Releases come full with the system source code in
|
|
.Pa /src
|
|
as a
|
|
.Xr git 1
|
|
repository along with the tools to build it and develop it.
|
|
The build process is covered in
|
|
.Xr development 7 .
|
|
.Ss Mounting
|
|
You can mount ext2 partitions using
|
|
.Xr extfs 8
|
|
and unmount them with
|
|
.Xr unmount 8 :
|
|
.Pp
|
|
.Dl $ extfs /dev/ahci0p1 /mnt
|
|
.Dl $ unmount /mnt
|
|
.Pp
|
|
Beware that
|
|
.Xr init 8
|
|
is unaware of manual mountpoints and powering off will not gracefully unmount.
|
|
The
|
|
.Xr extfs 8
|
|
driver only supports the
|
|
.Sy large_file
|
|
and
|
|
.Sy filetype
|
|
ext2 extensions.
|
|
You can make a compatible filesystem with:
|
|
.Pp
|
|
.Dl $ mkfs.ext2 -O none,large_file,filetype
|
|
.Ss Networking
|
|
Sortix does not have networking at this time.
|
|
Unix sockets have a basic implementation incapable of advanced features.
|
|
The standard library and kernel provides stubs for many network interfaces.
|
|
.Ss Serial Transfer
|
|
It is possible to transfer files over serial devices as described in
|
|
.Xr serial-transfer 7 .
|
|
.Ss Development
|
|
The system is self-hosting and is capable of building itself as described in
|
|
.Xr development 7 .
|
|
Ports are cross-compiled as described in
|
|
.Xr cross-development 7 ,
|
|
but it is becoming feasible to build a large number of them natively.
