# 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:
|
||
|
|
```
|
||
|
|
1
|
||
|
|
2
|
||
|
|
3
|
||
|
|
4
|
||
|
|
5
|
||
|
|
```
|
||
|
|
|
||
|
|
### 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.
