Quote:
print "Do you want to continue (y/n) ? " | tee -a /dev/tty
read answer
if [[ "$answer" = "y" || "$answer" = "Y" ]];
The above code is very unusual.
This would normal if you just want to read what someone typed in response to the question:
Code:
print "Do you want to continue (y/n) ? "
read answer
if  [[ "$answer" = "y" || "$answer" = "Y" ]];


Code:
I could not see $answer in my logs.

It would be helpful to see all the scripts.
If you are trying to read the value of $answer in the calling process, this is impossible. A variable created in a sub-script is not available to the calling script. There are techniques to get round this.
