bash script to capture shell output to clipboard, optionally the original command and print to stdout too.

clipify.sh

  -a    All: Include the command itself in the capture
  -s    Screen: Also print the final content to terminal (tee)
  -h    Display this help

  Note: Avoid large files (>100MB), binary data, ANSI colors,
        or subshells."
