 ### Processes
 
 A process is an instance of a running program: When a program is executed, the kernel assigns a **PID** (Process ID) to it, defines a **state** (wether it is running, stopped, etc), defines which process spawned the program, and assigns it **memory space** (or address space): Virtual memory, preventing the program from accessing the memory assigned to other processes.

 The kernel by itself isn't intractable, so a shell is needed for the user to be able to execute programs and run commands. Bash is not only a prompt, but also an interpreter for its own programming language, which can be used to write scripts and automate tasks.
 
+### Commands
+
+Bash performs actions through commands. A shell command consists of the command itself, followed by its arguments.
+
+```bash
+command "arg1" "arg2"
+```
+
+If the first word of a command is a reserved word, bash handles the command, otherwise, it searches for an executable on the system's `$PATH`, a list of directories where a binary could be located.
+
+### Bash Scripts
+
+Example `script.sh`:
+
+```bash
+#! /bin/bash
+
+echo "Bash Script"
+```
+
+Execute the script:
+
+```bash
+chmod u+x script.sh  # Give the script execution permission (to its owner)
+./script.sh          # Run the script
+```
+
+### Learning
+
+There are some commands available to search for documentation:
+
+```bash
+tldr command        # Examples of how to use the command (external tool)
+help command        # Short documentation for the command
+man command         # Full documentation for the command
+man bash            # Bash documentation; Includes most built-in commands
+```
+
+> To get started, use `help` by itself, which provides a list of the built-in commands available in bash.
+
+For example, suppose you want to learn how to write an `if` statement in `bash`:
