Bat
A cat clone with syntax highlighting, Git integration, and automatic paging.
What is Bat?
bat is a command-line utility that functions as a modern replacement for the traditional `cat` command. It adds syntax highlighting, Git integration, and automatic paging to file viewing, making it easier to read and navigate code and text files in the terminal. It solves the problem of plain text output by providing visual cues and contextual information.
Developers, system administrators, and anyone who frequently works in the terminal and wants enhanced file viewing capabilities. It's particularly useful for those who read code, configuration files, or logs directly from the command line.
Developers choose bat because it seamlessly integrates into existing workflows as a drop-in replacement for `cat`, while offering significant improvements like syntax highlighting and Git awareness. Its focus on performance, compatibility, and ease of use makes it a preferred tool for terminal-based file inspection.

Use Cases
Best For
- Viewing source code files with syntax highlighting in the terminal
- Inspecting Git changes directly in file diffs
- Reading log files with highlighted structure and important markers
- Previewing search results from tools like fzf or ripgrep
- Replacing cat in aliases and scripts for better output readability
- Displaying man pages or command help text with colorization
Not Ideal For
- Portable shell scripts that must run on any system without additional installations
- High-performance pipelines where minimal overhead and raw speed are critical
- Environments with strict resource constraints or minimal toolchains
- Viewing binary files or data with embedded ANSI escape sequences that cause garbled output
Pros & Cons
Pros
Supports a vast array of programming languages with customizable themes, as shown in the syntax highlighting example and the --list-themes option for easy theme switching.
Displays Git modifications in a sidebar, making it easy to see changes at a glance, which is particularly useful for code reviews and version control workflows.
Automatically pipes output to a pager like less for large files but falls back to cat-like behavior when piping to other processes, ensuring compatibility with existing scripts.
Works well with popular command-line tools like fzf, ripgrep, and find, enhancing previews and search results, as demonstrated in the integration examples.
Cons
On older Ubuntu/Debian systems, the executable is installed as batcat due to package name clashes, requiring manual aliasing or symlinking, which adds setup complexity.
Only natively handles UTF-8 and UTF-16 encodings; other encodings require external conversion with tools like iconv, as noted in the troubleshooting section.
Requires installing a separate pager like less for proper functionality on Windows, and has issues with Cygwin paths, making it less seamless in some environments.
