Description: A Bash script parameter is an argument passed to a script at the time of execution. These parameters allow scripts to be more dynamic and reusable, as they can receive different values with each execution. In Bash, parameters can be referenced using special variables, such as $1, $2, etc., where $1 represents the first argument, $2 the second, and so on. Additionally, $@ can be used to refer to all parameters passed to the script. This functionality is essential for creating scripts that require user interaction or need to process different data sets. Parameters can be used to modify the behavior of the script, allowing it to adapt to various situations without needing to change the source code. This not only saves time but also improves efficiency in managing repetitive tasks in operating systems, where automation is key for server and application management.
