kcat

Kcat is a command-line tool used on Unix-like systems for concatenating files. It takes multiple input files and outputs their contents to the console or a specified file. The name "kcat" stands for "kitty cat", inspired by the way cats concatenate themselves when lying together.

Kcat has several useful features, including the ability to concatenate binary files without corrupting their content. It intelligently handles different file formats, ensuring that each file is concatenated properly. The tool supports various options, allowing users to adjust the behavior as required.

Kcat performs well with large files and is designed to handle large data sets efficiently. It has a low memory footprint, ensuring smooth execution even with limited system resources. The tool is also available on multiple operating systems, including Linux, macOS, and Windows Subsystem for Linux.

Kcat provides an intuitive and user-friendly interface, making it easy to use for beginners and experts alike. It supports advanced usage scenarios, such as combining multiple files into a single output, redirecting output to a file, or appending content to an existing file.

The tool is highly configurable, allowing users to customize options such as line endings, line numbering, and delimiters. It also supports various output formats, including plain text, JSON, and XML. Kcat includes error handling mechanisms, providing detailed error messages and exit codes to help diagnose any issues with file concatenation.

Kcat has gained popularity within the developer community for its simplicity, reliability, and extensive functionality. It is often favored over traditional concatenation methods due to its versatility and ease of use.
