Common Use Cases

Quick file preview:

bat file.json

View logs with syntax highlighting:

bat error.log

Compare files visually:

bat --diff file1.txt
bat file2.txt

Preview before editing:

bat config.yaml && vim config.yaml

Cat replacement in pipes:

bat -p file.txt | grep "pattern"

View specific function:

bat -r 45:67 script.py  # If function is on lines 45-67

Integration with other tools

As pager for man pages:

export MANPAGER="sh -c 'col -bx | bat -l man -p'"
man grep

With ripgrep:

rg "pattern" -l | xargs bat

With fzf:

fzf --preview 'bat --color=always --style=numbers {}'

With diff:

diff -u file1 file2 | bat -l diff

Configuration

Create ~/.config/bat/config for defaults:

# Set theme
--theme="Dracula"

# Show line numbers, Git modifications and file header, but no grid
--style="numbers,changes,header"

# Use italic text on terminal
--italic-text=always

# Add custom mapping
--map-syntax "*.conf:INI"

Performance Tips

Use -p for plain mode when piping
Use --paging=never when output is used programmatically
bat caches parsed files for faster subsequent access

Tips

Alias: alias cat='bat -p' for drop-in cat replacement
Pager: Use as pager with export PAGER="bat"
On Debian/Ubuntu: Command may be batcat instead of bat
Custom syntaxes: Add to ~/.config/bat/syntaxes/
Performance: For huge files, use bat --paging=never or plain cat

Common flags

-p / --plain: Plain mode (no line numbers/decorations)
-n / --number: Only show line numbers
-A / --show-all: Show non-printable characters
-l / --language: Set language for syntax highlighting
-r / --line-range: Only show specific line range(s)
