Description: A variable in Bash is a container that stores data that can be used and manipulated within scripts and commands. These variables allow users to temporarily store information, facilitating task automation and script customization. In Bash, variables are defined without the need for a specific data type, meaning they can hold strings, numbers, or even command results. To assign a value to a variable, the syntax ‘variable_name=value’ is used, with no spaces around the equal sign. Variables can be local, limited to the script’s context, or global, accessible from anywhere in the Bash environment. Additionally, Bash allows variable expansion, meaning they can be used in other commands or scripts, increasing their versatility. Variable management is fundamental to programming in shell environments, as it enables the creation of more dynamic and adaptable scripts for different situations and user inputs.
