This example demonstrates a shell script that renames files by stripping the first prefix from each filename, up to and including the first period. It shows a concise file-management task rather than a data visualization. The code iterates over all files in the current directory using a `for` loop and applies the `mv` command with parameter expansion (`${file#*.}`) to remove the shortest prefix ending in a period. No external libraries or rendering APIs are involved; the logic relies solely on standard Unix shell constructs and the `mv` utility. The data source is the filesystem, and the output is the renamed files.
