I'm pretty new at shell scripts, but I would like to write a basic script where the bash file will echo a different line of text depending on the user input. For example if the script asks the user "Are you there?" and the user input is "yes" or "Yes" then the script would echo something like "hello!". But if the user input is "no" or "No" the script would echo something else. And finally, if the user input is something other than yes/Yes or no/No, the script would echo "Please answer yes or no". Here is what I have so far:
echo "Are you there?" read $input if [ $input == $yes ]; then echo "Hello!" elif [ $input == $no ]]; then echo "Are you sure?" else echo "Please answer yes or no." fi
However, no matter the input, I always get the first response ("Hello!")
Also, I would like to incorporate text to speech (as I have done with other bash file projects using festival). In other bash files I have done it this way:
echo "Hello!" echo "Hello!" | festival --tts
Is there a way to incorporate this into the if then/yes no prompt above? Thank you in advance, I'm using this to make simple bash files and to help myself learn.
