During boot MOROS will display its version followed by the memory layout, memory size, processor, devices, network cards, disks, and the real time clock.

commands to test the system or install to setup the
filesystem on a disk:

Installation successful!
Quit the console or reboot to apply changes
You can then use ^D (a key combination of CTRL and D) to quit the
diskless mode and let MOROS run the bootscript /ini/boot.sh to login and use
the shell.
If no disks were detected or if you prefer not to use them you can mount the
system in memory to use a virtual disk with memory format before install.
The shell is the primary command line interface to use MOROS. This is were you can type a command and its arguments to tell the system what to do:
~
> print "Hello, World!"
Hello, World!
The system has a help command to help you remember the basic commands.
Most commands also have a special --help argument to show all their options.
The line above the command prompt tells you where you are in the disk. The
tilde ~ means that you are in your home directory:
~
> print $DIR
/usr/vinc
You can change directory by typing it as if it was a command:
~
> /tmp
/tmp
> print $DIR
/tmp
From now on we'll omit the directory line in most examples.
You can list the content of a directory with list:
> list /tmp
5090 2023-04-17 06:25:54 alice.txt
82 2023-04-17 06:25:55 beep
324 2023-04-17 06:25:55 life
168 2023-04-17 06:25:55 lisp
649 2023-04-17 06:25:54 machines.txt
The command has some options to sort the results:
> list --help
Usage: list <options> [<dir>]
Options:
-a, --all Show dot files
-n, --name Sort by name
-s, --size Sort by size
-t, --time Sort by time
You can write a directory in the disk with write:
> write test/
> list
5090 2023-04-17 06:25:54 alice.txt
82 2023-04-17 06:25:55 beep
324 2023-04-17 06:25:55 life
168 2023-04-17 06:25:55 lisp
649 2023-04-17 06:25:54 machines.txt
0 2023-04-17 07:06:18 test
The slash / at the end of test/ is there to tell the write command to
create a directory instead of a file.
You can create a file by redirecting the output of a command with an arrow =>
to the file:
> print "Hello, World!" => hello.txt
The command read will read the content of the file:
> read hello.txt
Hello, World!
You can edit a file with the edit command that will run the text editor.
Use ^W (a key combination of CTRL and W) inside the editor to write the
content to the file and ^Q to quit the editor and go back to the shell.
The help command has a subcommand help edit to list the editor commands:
> help edit
MOROS text editor is a very simple editor inspired by Pico, Nano, and Micro.
Commands:
^Q Quit editor
^W Write to file
^X Write to file and quit
^T Go to top of file
^B Go to bottom of file
^A Go to beginning of line
^E Go to end of line
^D Cut line
^Y Copy line
^P Paste line
You can print the date with date:
> date
2001-01-01 00:00:00 +0000
You can update the real time clock by writing the correct time to its device file:
> print "2023-03-21 10:00:00" => /dev/rtc
> date
2023-03-21 10:00:00 +0000
You can also set the TZ environment variable to use your preferred timezone:
> calc "2 * 60 * 60"
7200
> env TZ 7200
> date
2023-03-21 12:00:00 +0200
Add env TZ 7200 to /ini/boot.sh before shell to save the timezone:
> read /ini/boot.sh
vga set palette /ini/palettes/gruvbox-dark.csv
vga set font /ini/fonts/zap-light-8x16.psf
read /ini/banner.txt
user login
env TZ 7200
shell
There's a device file to get the number of seconds elapsed since Unix Epoch:
> read /dev/clk/realtime
1682105344.624905
And another one since boot:
> read /dev/clk/uptime
1169.384929
You can add custom commands to the shell with the alias command.
For example you can define an uptime command that will read the device file
described above:
> alias uptime "read /dev/clk/uptime"
> uptime
1406.304852
You can add that command to /ini/shell.sh to save it.
Some shortcuts have been defined in that file for the most frequent commands,
for example you can use e instead of edit to edit a file.
> read /ini/shell.sh
# Command shortcuts
alias c copy
alias d delete
alias e edit
alias f find
alias h help
alias l list
alias m move
alias p print
alias q quit
alias r read
alias w write
alias sh shell
alias dsk disk
alias mem memory
alias kbd keyboard
You can setup the network manually with net or automatically
with dhcp:
> dhcp
ip: 10.0.2.15/24
gw: 10.0.2.2
dns: 10.0.2.3
