+  Ctrl + e   Go to the End of the line (End)
+  Ctrl + p   Previous command (Up arrow)
+  Ctrl + n   Next command (Down arrow)
+   Alt + b   Back (left) one word
+   Alt + f   Forward (right) one word
+  Ctrl + f   Forward one character
+  Ctrl + b   Backward one character
+  Ctrl + xx  Toggle between the start of line and current cursor position
+```
+
+### Editing
+
+```bash
+Ctrl + L   Clear the Screen, similar to the clear command
+
+  Alt + Del Delete the Word before the cursor.
+  Alt + d   Delete the Word after the cursor.
+ Ctrl + d   Delete character under the cursor
+ Ctrl + h   Delete character before the cursor (Backspace)
+
+ Ctrl + w   Cut the Word before the cursor to the clipboard.
+ Ctrl + k   Cut the Line after the cursor to the clipboard.
+ Ctrl + u   Cut/delete the Line before the cursor to the clipboard.
+
+  Alt + t   Swap current word with previous
+ Ctrl + t   Swap the last two characters before the cursor (typo).
+ Esc  + t   Swap the last two words before the cursor.
+
+ ctrl + y   Paste the last thing to be cut (yank)
+  Alt + u   UPPER capitalize every character from the cursor to the end of the current word.
+  Alt + l   Lower the case of every character from the cursor to the end of the current word.
+  Alt + c   Capitalize the character under the cursor and move to the end of the word.
+  Alt + r   Cancel the changes and put back the line as it was in the history (revert).
+ ctrl + _   Undo
+ 
+ TAB        Tab completion for file/directory names
+```
+
+### Special keys
+
+Text Terminals send characters (bytes), not key strokes.
+Special keys such as Tab, Backspace, Enter and Esc are encoded as control characters.
+Control characters are not printable, they display in the terminal as ^ and are intended to have an effect on applications.
+
+```bash
+Ctrl+I = Tab
+Ctrl+J = Newline
+Ctrl+M = Enter
+Ctrl+[ = Escape
+
+Many terminals will also send control characters for keys in the digit row:
+Ctrl+2 → ^@
+Ctrl+3 → ^[ Escape
+Ctrl+4 → ^\
+Ctrl+5 → ^]
+Ctrl+6 → ^^
+Ctrl+7 → ^_ Undo
+Ctrl+8 → ^? Backward-delete-char
+
+Ctrl+v tells the terminal to not interpret the following character, so Ctrl+v Ctrl-I will display a tab character,
+similarly Ctrl+v ENTER will display the escape sequence for the Enter key: ^M
+```
+
+### History
+
+```bash
+  Ctrl + r   Recall the last command including the specified character(s).
+             searches the command history as you type.
+             Equivalent to : vim ~/.bash_history. 
+  Ctrl + p   Previous command in history (i.e. walk back through the command history).
+  Ctrl + n   Next command in history (i.e. walk forward through the command history).
+
+  Ctrl + s   Go back to the next most recent command.
+             (beware to not execute it from a terminal because this will also launch its XOFF).
+  Ctrl + o   Execute the command found via Ctrl+r or Ctrl+s
+  Ctrl + g   Escape from history searching mode
+        !!   Repeat last command
+       !n    Repeat from the last command: args n e.g. !:2 for the second argumant.
+       !n:m  Repeat from the last command: args from n to m. e.g. !:2-3 for the second and third.
+       !n:$  Repeat from the last command: args n to the last argument.
+       !n:p  Print last command starting with n
+     !string Print the last command beginning with string.
+       !:q   Quote the last command with proper Bash escaping applied.
+              Tip: enter a line of Bash starting with a # comment, then run !:q on the next line to escape it.
+        !$   Last argument of previous command.
+   ALT + .   Last argument of previous command.
+        !*   All arguments of previous command.
+^abc­^­def   Run previous command, replacing abc with def
+```
+
+### Process control
+
+```bash
+ Ctrl + C   Interrupt/Kill whatever you are running (SIGINT).
+ Ctrl + l   Clear the screen.
+ Ctrl + s   Stop output to the screen (for long running verbose commands).
+            Then use PgUp/PgDn for navigation.
+ Ctrl + q   Allow output to the screen (if previously stopped using command above).
+ Ctrl + D   Send an EOF marker, unless disabled by an option, this will close the current shell (EXIT).
+ Ctrl + Z   Send the signal SIGTSTP to the current task, which suspends it.
+            To return to it later enter fg 'process name' (foreground).

 # RUST
 
-### Basic cli tools 
+## Basic cli tools 
 
 - `cargo init` ~ create new rust project
 - `cargo run` ~ build & run
 - `cargo build` ~ just build
 - `cargo build --release` ~ minimal release version (optimized)
+
+## Rust basics
+
+
+### Arrays
+
+```rust
+// Arrays are allocated on stack just like in C
+pub fn run() {
+  let mut numbers: [i32; 5] = [1, 2, 3, 4, 5];
+
+  numbers[2] = 20; // [1, 2, 20, 4, 5] 
+
+  println!("Single value: {}", numbers[0]);  // 1
+
+  println!("Array length: {}",numbers.len()); // 5
+
+  // Arrays are stack allocated
+  println!("Array occupies {} bytes", std::mem::size_of_val(&numbers)); // 20 bytes
+
+  // Get slice
+  let sliced: &[i32] = &numbers[0..2];
+  println!("Sliced: {:?}", sliced); // [1, 2]
+}
+```
+
+### CLI arguments
+
+```rust
+use std::env;
+
+pub fn run() {
+  let args: Vec<String>  = env::args().collect();
+  let command = args[1].clone();
+  let name = "spanskiduh";
+
+  println!("Command: {}", command);
+
+  if command == "hello" {
+    println!("Hi {}, how are you?", name);
+  }
+}
+```
+
+### Conditionals
+
+```rust
+// Conditionals - Used to check the condition of something and act on the result
+
+pub fn run() {
+  let age: u8 = 18;
+  let check_id: bool = false;
+  let knows_person_of_age = true;
+
+  // If / Else
+  if age >= 21 && check_id || knows_person_of_age {
+    println!("bartender: What would you like to drink?"); // This gets printed
+  } else if age < 21 && check_id{
+    println!("bartender: Sorry, you have to leave.");
+  } else {
+    println!("bartender: I'll need to see your ID");
+  }
+
+  // Shorthand If (similar to terminary operator)
+  let is_of_age = if age >= 21 {true} else {false};
+}
+```
+
+### Enums
+
+```rust
+
+enum Movement {
+  Up,
+  Down,
+  Left,
+  Right
+}
+
+fn move_avatar(m: Movement) {
+  match m {
+    Movement::Up => println!("Avatar moving up"),
+    Movement::Down => println!("Avatar moving down"),
+    Movement::Left => println!("Avatar moving left"),
+    Movement::Right => println!("Avatar moving right"),
+  }
+}
+
+pub fn run() {
+  let avatar1 = Movement::Left;
+  let avatar2 = Movement::Up;
+  let avatar3 = Movement::Right;
+  let avatar4 = Movement::Down;
+
+  move_avatar(avatar1);
+  move_avatar(avatar2);
+  move_avatar(avatar3);
+  move_avatar(avatar4);
+}
+```
+
+### Functions
+
+```rust
+pub fn run() {
+  greeting("Hello", "Jane");
+
+  // Bind function values to variables
+  let get_sum = add(5, 5);
+  println!("Sum: {}", get_sum);
+
+  // Closure 
+  let n3: i32 = 10;
+  let add_nums = |n1: i32, n2: i32 | n1 + n2 + n3;
+  println!("C Sum: {}", add_nums(3,3)); // 16
+}
+
+fn greeting(greet: &str, name: &str) {
+  println!("{} {}, nice to meet you!", greet, name);
+}
+
+fn add(n1: i32, n2: i32) -> i32 {
+  n1 + n2
+}
+```
+
+### Loops
+
+```rust
+// Loops - Used to iterate until a condition is met
+
+pub fn run(){
+
+  let mut count = 0;
+  
+  // Infinite Loop
+  loop {
+    count += 1;
+    println!("Number: {}", count);
+
+    if count == 20 {
+      break;
+    }
+  }
+
+  // While loop (FizzBuzz)
+  while count <= 100 {
+    if count % 15 == 0 {
+      println!("FizzBuzz");
+    } else if count % 3 == 0 {
+      println!("Fiz");
+    } else if count % 5 == 0 {
+      println!("Buzz");
+    } else {
+      println!("{}", count);
+    }
+    count += 1;
+  }
+
+  // For range
+  for x in 0..100 {
+    if x % 15 == 0 {
+      println!("FizzBuzz");
+    } else if x % 3 == 0 {
+      println!("Fiz");
+    } else if x % 5 == 0 {
+      println!("Buzz");
+    } else {
+      println!("{}", x);
+    }
+  }  
+}
+```
+
+### Pointer references
+
+```rust
+// With non-privitieves, if you assign another variable to a piece of data, the
+// first varaible will no longer hold that value. You'll need to use a reference
+// (&) to point to the resource.
+
+pub fn run() {
+  // Primitive array
+  let arr1 = [1, 2, 3];
+  let arr2 = arr1;
+  
+  // Vector
+  let vec1 = vec![1, 2, 3];
+  let vec2 = &vec1;
+  println!("{:?}", (arr1, arr2)); // ([1, 2, 3], [1, 2, 3])
+  println!("{:?}", (&vec1, vec2)); // ([1, 2, 3], [1, 2, 3])
+}
+```
+
+### Format strings
+```rust
+pub fn run() {
+    // Print to console
+    println!("Hello from print.rs file");
+    
+    println!("{} se uci {}", "Gasper", "rust");
+
+    // Positional args
+    println!("{0} is from {1} and {0} likes to {2}", "Gasper", "SLovEniA", "program");
+    
+    // Named args
+    println!("{name} likes to play {activity}", name = "John", activity = "Tennis");
+
+    // Placeholder traits
+    println!("Binary: {:b} Hex: {:x} Octal: {:o}", 10, 10, 10); // Binary: 1010 Hex: a Octal: 12 
+
+    // Placeholder for debug trait
+    println!("{:?}", (12, true, "hello")); // (12, true, "hello") 
+
+    // Basic math
+    println!("10 + 10 = {}", 10 + 10);
+}
+```
+### String manipulation
+
+```rust
+// Primitve str = Immutable fixed-length string somewhere in memory
+// String = Growable, heal-allocated data structure - Use when you need to modify
+// or own strign data
+
+pub fn run() {
+  let hello = "Hello"; // Primitve
+  let mut growale_hello = String::from("Hello "); // Growable
+
+  // Get string length, works for both types
+  println!("Length: {}", hello.len());
+
+  // Append, only Growable
+  growale_hello.push('W');
+  growale_hello.push_str("orld!");
+
+  // Capacity in bytes (work on both)
+  println!("Capacity: {}", growale_hello.capacity());
+  
+  println!("Is Empty: {}", hello.is_empty());
+  println!("Is Empty: {}", growale_hello.is_empty());
+
+  // Substring??
+  println!("{} -> Contains 'World' {}", hello, hello.contains("World"));
+  println!("{} -> Contains 'World' {}", growale_hello, growale_hello.contains("World"));
+
+  // Replace
+  println!("Replace: {}", growale_hello.replace("World", "Bro"));
+  println!("Replace: {}", hello.replace("Hello", "Bye"));
+
+  // Loop through string by whitespace
+  for word in growale_hello.split_whitespace() {
+    println!("{}", word);
+  }
+  
+  // Create string with predefined capacity
+  let mut s = String::with_capacity(10);
+  s.push('a');
+  s.push('b');
+  println!("{}", s); // ab 
+
+  // Assertion testing
+  assert_eq!(2, s.len());
+  assert_eq!(10, s.capacity());
+}
+
+### Structs
+
+```rust
+// Traditional struct
+struct Color {
+  red: u8,
+  green: u8,
+  blue: u8,
+}
+
+// Tuple struct
+struct Color2(u8, u8, u8);
+
+struct Person {
+  first_name: String,
+  last_name: String
+}
+
+impl Person {
+  // Construct person
+  fn new(first: &str, last: &str) -> Person {
+    Person {
+      first_name: first.to_string(),
+      last_name: last.to_string()
+    }
+  }
+
+  // Get full name
+  fn full_name(&self) -> String {
+    format!("{} {}", self.first_name, self.last_name)
+  }
+
+  // Set last name
+  fn set_last_name(&mut self, last:&str) {
+    self.last_name = last.to_string();
+  }
+
+  // Name to tuple
+  fn to_tuple(self) -> (String, String) {
+    (self.first_name, self.last_name)
+  }
+}
+
+pub fn run() {
+  let mut c = Color {
+    red: 255,
+    green: 0,
+    blue: 0
+  };
+
+  c.red = 200;
+  println!("color: {} {} {}", c.red, c.green, c.blue);
+
+  let mut c2 = Color2(255, 0, 0);
+
+  c2.0 = 200;
+  println!("color: {} {} {}", c2.0, c2.1, c2.2);
+
+  let mut p = Person::new("Marry", "Doe");
+  println!("Person {} {}", p.first_name, p.last_name);
+  p.set_last_name("Doee");
+  println!("Person {}", p.full_name());
+  println!("Person tuple {:?}", p.to_tuple());
+}
+```
+### Tuples
+
+```rust
+
+// Max 12 elements, diffrent types allowed
+
+pub fn run() {
+   let person: (&str, &str, i8) = ("Gasper", "NG", 22);
+   println!("{} is from {} and is {}", person.0, person.1, person.2);
+}
+```
+
+### Types 
+
+```rust
+pub fn run() {
+   // default is "i32"
+   let x = 1;
+
+   // default is "f64"
+   let y = 2.5;
+
+   // Add explicit type
+   let z: i64 = 33213123;
+
+   // Find max size
+   println!("Max i32: {}", std::i32::MAX);
+   println!("Max i64: {}", std::i64::MAX);
+
+   // Boolean
+   let is_active: bool = true;
+   
+   // Get boolean from expression
+   let is_greater:bool = 10 > 5;
+
+   let a1 = 'a';
+   let face = '\u{1F600}';
+
+   println!("{:?}", (x, y, z, is_active, is_greater, a1, face)); // (1, 2.5, 33213123, true, true, 'a', '😀')
+}
+```
+
+### Variables
+
+```rust
+// Variables hold primitive data or references to data
+// Variables are immutable by default (u cannot reasign them)
+// Rust is a block-scoped language
+
+pub fn run() {
+   let name = "Gasper"; 
+   let mut age = 22;
+   let mut i_mutate: i128 = 42069;
+
+   println!("My name is {} and I am {}", name, age);
+
+   // Chage vaue 
+   age = 23;
+
+   // Define constant
+   const ID: i32 = 001;
+
+   // Assign multiple vars
+   let (my_name, my_age) = ("Gasper", 200);
+
+   let mut i = 0;
+   while i < 10 {
+      i_mutate = i_mutate + 420;
+      println!("Value: {}", i_mutate);
+      i = i + 1;
+   }
+}
+```
+
+### Vectors
+
+```rust
+
+// Vectors are resizable arrays stored on a heap
+use std::mem;
+
+pub fn run() {
+  let mut numbers: Vec<i32> = vec![1, 2, 3, 4, 5];
+
+  // Assign a value
+  numbers[2] = 20;  
+  // Add on to a vector  
+  numbers.push(5);
+  numbers.push(6);
+
+  // Pop off last value
+  numbers.pop(); // [1, 2, 20, 4, 5, 5]
+
+  println!("Single value: {}", numbers[0]); // 1
+
+  println!("Vector length: {}",numbers.len()); // 6
+
+  // Vectors are heap allocated
+  println!("Vector occupies {} bytes", mem::size_of_val(&numbers)); // 24
+
+  // Get slice
+  let sliced: &[i32] = &numbers[0..2];
+
+  println!("Sliced: {:?}", sliced); // Sliced: [1, 2]
+  
+  // Loop through vector values
+  for x in numbers.iter() {
+    println!("Number: {}", x);
+  }
+
+  // Loop and mutate values
+  for x in numbers.iter_mut() {
+    *x *= 2;
+  } // [2, 4, 40, 8, 10, 10]

 ## Usage of wabt
 
-- wat2wasm: translate from WebAssembly text format to the WebAssembly binary format
-- wasm2wat: the inverse of wat2wasm, translate from the binary format back to the text format (also known as a .wat)
-- wasm-objdump: print information about a wasm binary. Similiar to objdump.
-- wasm-interp: decode and run a WebAssembly binary file using a stack-based interpreter
-- wasm-decompile: decompile a wasm binary into readable C-like syntax.
-- wat-desugar: parse .wat text form as supported by the spec interpreter (s-expressions, flat syntax, or mixed) and print "canonical" flat format
-- wasm2c: convert a WebAssembly binary file to a C source and header
-- wasm-strip: remove sections of a WebAssembly binary file
-- wasm-validate: validate a file in the WebAssembly binary format
-- wast2json: convert a file in the wasm spec test format to a JSON file and associated wasm binary files
-- wasm-opcodecnt: count opcode usage for instructions
-- spectest-interp: read a Spectest JSON file, and run its tests in the interpreter
