utility function to copy all the contents of a text file from the terminal

copy-files.sh

#pbcopy only exists on OSX (as far as I know), for linux find an equivalent
function cp-file-contents() {
    if [ $# -eq 0 ]
    then echo "Missing arguments"
    elif [ $# -gt 1 ]
    then echo "Too many arguments"
    else
        cat $1 | pbcopy
        echo "contens copied"
    fi
}
