How can I insert a word inside a command in Linux? - bash

Question

Now, I have a simple file that runs every time I open my Gitpod(cloud env). I am making a file so that I can access it via ngrok. But, I need some packages, like wget, unzip and neofetch(for my ease). But it opens in a different terminal and I have to enter y every time. Is there a way to put y in the command and it will install automatically?
Source code for the file:
#!/bin/bash
sudo apt update
sudo apt install wget unzip openssh-server neofetch -y
sudo service ssh start
echo "Set Password for Gitpod as gitpod"
sudo passwd gitpod
wget "https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip"
unzip "ngrok-stable-linux-amd64.zip"
echo "I need your ngrok auth token. Enter it below."
read -p "ngrok authtoken:" authtoken
./ngrok authtoken $authtoken
echo "Authtoken activated, now activating server..."
./ngrok tcp 22
sudo apt install wget unzip openssh-server neofetch -y
Have I put correctly in this line? If this works, whenever I get a cloud environment, it could just install all deps and go ahead.

Yeah its a cloud Gitpod env for my blog and I want SSH tunneled via ngrok but it says this:
/repo > .gitpod/ngrok.sh: 5: y: not found
How can I fix this? The mod deleted the last output so please don't delete this! It is mainly an output of the Gitpod Terminal.

Answer 1

You can add an echo command in your script and use this as a standard input for your next command.
echo y | [next-command]

Answer 2

Please don't delete.
By #Biffen and this is the solution!
That error doesn’t look like the result of the code in the question. Are you running the strange suggestion in one of the answers; | y? That won’t work. Have a look at this.
Thanks to everyone who helped here, and I am marking this as answer, because Biffen's reply was a comment.
Edit: In 2 days as of now, I can mark this as answer, because, Stack Overflow said so.
