awk - split a fixed width file into separate files named on content

This technical blog post explains how to use the Unix awk command to split a fixed-width file (without delimiters) into multiple files. The filenames are dynamically generated based on the content extracted from specific character positions (columns 14-16) within each line of the input file. It includes code examples and discusses the performance benefits of using lightweight command-line tools over heavier ETL software.
