bat is a command-line tool that replaces the standard cat utility with syntax highlighting and Git integration.
The tool solves the problem of viewing file contents in the terminal with minimal visual context. bat adds syntax highlighting across a large number of programming and markup languages, making code easier to read at a glance. It integrates with Git to display file modifications as a sidebar, showing changes relative to the index. The tool automatically detects when output should be paged for long files and falls back to plain output when piped to another process, preserving cat's behavior as a drop-in replacement. It can also display non-printable characters with highlighting when requested.
Developers should choose bat if they frequently read source code in the terminal and want better visual distinction between syntax elements without leaving the command line. It suits any workflow where cat is currently used but would benefit from syntax awareness. The tool works well integrated with other command-line utilities like fzf, find, fd, and ripgrep through standard piping and option flags. bat's automatic paging and intelligent output detection mean it can replace cat directly in shell aliases without breaking existing scripts or piped commands.
The project maintains active continuous integration workflows. Development follows a structured approach with clear configuration and customization options documented in the README. The tool is written in Rust, indicating a focus on performance and reliability for a frequently-used command-line utility.
