PsychOS user guide

Useful key combinations:

ctrl-shift-c inside PsychOS will cancel text input or stop certain programs.

ctrl-shift-r will soft-reboot the machine, preserving the content of /tmp.

The lush shell

lush is the default shell of PsychOS. It allows executing functions in memory, programs on disk and Lua typed directly into lush, in order of preference.

The default prompt is [<user>@<hostname> <current directory>]$

Some example usage:

running a function

[user@host /boot]$ =ps  
function: 0x12ed5c0

This is checking if ps is indeed a function.

[user@host /boot]$ ps  
PID     User    Name  
3       superu  logflushd  
4       superu  ncd  
5       superu  tty[randomstringabcd]: 8f01b7c7,89734f0  
6       superu  kbd: 1f46ed58  
7       superu  kbd-clibboard: 1f46ed58  
8       superu  login manager: randomstringabcd

This runs the ps function. You can also have arguments following the function name, separated by spaces.

running a program on disk

You have the following program stored as count.lua, in the current directory:

for i = 1, 5 do  
 print(i)  
end

To run it, all you need to do is:

[user@host /boot]$ count

You should get the expected output:

running Lua code

Running Lua from lush is also simple, in that you just type it in.

[user@host /boot]$ for i = 1, 5 do print(i) end

You should get the same output as the last example.
