# Bash Cheatsheet
Bash is a Unix shell and command language used for automating tasks and interacting with the operating system. Here is an overview of its features, code blocks, and resources.
## Features
- Bash is a command language used for interacting with the Unix shell.
- It is a scripting language that can be used for automating tasks and system administration.
- Bash supports variables, loops, conditionals, functions, and file manipulation.
- Bash is highly customizable and can be extended with plugins and scripts.
## Code Blocks
### Variables
Variables are used to store data that can be used later in the script.
```bash
variableName=value
```
### Functions
Functions are code blocks that perform a specific task. They can be called by other parts of the script.
```bash
function functionName {
# code to be executed
}
```
### Conditionals
Conditionals allow the script to make decisions based on certain conditions.
```bash
if [ condition ]; then
# code to be executed if condition is true
elif [ otherCondition ]; then
# code to be executed if otherCondition is true
else
# code to be executed if neither condition is true
fi
```
### Loops
Loops allow the script to repeat a set of instructions.
```bash
for i in {1..10}; do
# code to be executed
done
```
### File Manipulation
Bash can be used to manipulate files and folders on the file system.
```bash
# list all files in the current directory
ls
# create a new directory
mkdir directoryName
# remove a file
rm fileName
```
