Description: Bash script variables are used to store data within a script. These variables allow programmers and system administrators to handle information dynamically, facilitating the creation of more flexible and reusable scripts. In Bash, variables do not require an explicit type declaration, meaning they can hold different types of data, such as strings, numbers, or lists. To assign a value to a variable, the syntax ‘variable_name=value’ is used, with no spaces around the equal sign. Variables can be accessed later in the script using the ‘$’ prefix, allowing their use in commands and expressions. Additionally, Bash offers the possibility of defining environment variables, which are accessible to all processes running in the same environment, making it useful for sharing configurations and data between different scripts and applications. Proper variable management is essential for efficiency and clarity in script writing, as it allows for customization and adaptation of scripts to different contexts and needs.
