Append to bashrc to add better copying
# A shortcut function that simplifies usage of xclip.
# - Accepts input from either stdin (pipe), or params.
# Taken from:
# ------------------------------------------------
cb() {
local _scs_col="\e[0;32m"; local _wrn_col='\e[1;31m'; local _trn_col='\e[0;33m'
# Check that xclip is installed.
if ! type xclip > /dev/null 2>&1; then
echo -e "$_wrn_col""You must have the 'xclip' program installed.\e[0m"
# Check user is not root (root doesn't have access to user xorg server)
elif [[ "$USER" == "root" ]]; then
echo -e "$_wrn_col""Must be regular user (not root) to copy a file to the clipboard.\e[0m"
# If no tty, data should be available on stdin
if ! [[ "$( tty )" == /dev/* ]]; then
input="$(< /dev/stdin)"
# Else, fetch input from params
if [ -z "$input" ]; then # If no input, print usage message.
echo "Copies a string to the clipboard."
echo "Usage: cb <string>"
echo " echo <string> | cb"
# Copy input to clipboard
echo -n "$input" | xclip -selection c
# Truncate text for status
if [ ${#input} -gt 80 ]; then input="$(echo $input | cut -c1-80)$_trn_col...\e[0m"; fi
# Print status.
echo -e "$_scs_col""Copied to clipboard:\e[0m $input"
# Aliases / functions leveraging the cb() function
# ------------------------------------------------
# Copy contents of a file
function cbf() { cat "$1" | cb; }
# Copy SSH public key
alias cbssh="cbf ~/.ssh/"
# Copy current working directory
alias cbwd="pwd | cb"
# Copy most recent command in bash history
alias cbhs="cat $HISTFILE | tail -n 1 | cb"
