cbcopy

#!/usr/bin/env bash
#
# Requirements: xclip
#
# Author: James Cherti
# URL: https://github.com/jamescherti/bash-stdops
#
# Description:
# ------------
# This script copies the contents of standard input to the clipboard.
#
# It intelligently chooses the appropriate method for the current environment:
# - If running on macOS with pbcopy available, it uses pbcopy.
# - If running in an X11 environment with xclip available, it uses xclip.
#
# Usage:
#   echo text | cbcopy
#
# The script handles both GUI and non-GUI environments for clipboard
# management.
