Bash (Bourne Again SHell) is a widely-used shell and command language interpreter in Unix and Linux operating systems. Bash scripts are sequences of commands written in the Bash language and executed in a Bash environment.

This README provides a basic understanding of Bash scripting, covering key aspects such as script structure, syntax, variables, conditionals, loops, functions, and how to run a Bash script.

A Bash script typically follows this structure:

#!/bin/bash

# Your script commands here
# ...

The #!/bin/bash line, known as the shebang, tells the system to use Bash to interpret the script.

Comments in Bash start with # and are used to annotate the script with human-readable information. Comments are ignored during script execution.

Variables in Bash are assigned using the syntax variable_name=value. Example:

greeting="Hello, World!"
echo $greeting

• If-else statement:

  if [ condition ]; then
      # commands if condition is true
  else
      # commands if condition is false
  fi

• Case statement:

  case $variable in
      pattern1)
          # commands for pattern1
          ;;
      pattern2)
          # commands for pattern2
          ;;
      *)
          # default commands
          ;;
  esac

• For loop:

  for i in {1..5}; do
      # commands
  done

• While loop:

  while [ condition ]; do
      # commands
  done

Functions in Bash are defined and called using the following syntax:

function_name() {
    # function body
}

# Call the function
function_name

1. Make the script executable:

   chmod +x script_name.sh

2. Run the script:

   ./script_name.sh
