A minimal terminal utility for clipboard operations using OSC52 escape sequences.

# Copy from stdin
echo "hello world" | cb

# Copy from file
cb filename.txt

# Paste to stdout
cb

# Paste to file
cb > filename.txt

• Copy: Encodes input as base64 and sends to terminal clipboard via OSC52
• Paste: Requests clipboard content from terminal and decodes base64 output
• Input limit: 10MB maximum for security
• Terminal detection: Automatically handles piped vs terminal output
• Multiplexer support: Wraps OSC52 in DCS passthrough for tmux

gcc -o cb cb.c

or use make to also install to /usr/local/bin

make install

Terminal emulator with OSC52 clipboard support (most modern terminals).
