# 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.

### Functions Functions are code blocks that perform a specific task. They can be called by other parts of the script.

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
