Interesting History
The concept of removing empty lines dates back to the early days of text processing in the 1960s. The Unix command 'grep' and 'sed', created by Ken Thompson in 1973, were among the first tools to offer empty line removal capabilities. This fundamental text processing operation became crucial in programming and data processing, leading to its implementation in various text editors and IDEs. Today, it remains an essential tool in text processing and data cleaning workflows.
