Concat function return with string for "read -p"

bash-concat-example.sh

# DESCRIPTION: Simple example of "read -p" and it's usage when trying to print a simple concat from a function and a user input 

# Here we'll assume "$folder" comes from a previously-checked "getopts options" loop 
# (given as an argument for our script/command option, like "ourscript -f MyFolderName")

# Print a styled "important:" text 
# This will be the usual "echo"-ed text that we need to concat for "read -p [message]"
info_message() {
  declare the_message="$1"
  echo -e "'IMPORTANT:' $the_message"
}

######### Concat given string from function "echo" return #########

# Execute "info_message()" passing a concatenated string as $1
# Note the escaped backslashes on ${folder} for this string 
folder_info=$(info_message "\"${folder}\" does not exist, do you want to create it? [Y/n]");

# Just use "$folder_info" string-type as a variable
# In this case, "info_message()" will "echo" the whole string 
read -p "${folder_info}" yn
