Variables in Bash scripting are used to store information that can be referenced and manipulated later in the script. Defining a variable is simple—just use the format variable_name=value without spaces. To access the value, prefix the variable name with a dollar sign, like $variable_name. Variables can hold text, numbers, or even the result of a command. They are essential for creating dynamic scripts that can adapt to different inputs or environments, making your shell scripts more powerful and reusable.
