I need a bash script that would create a pop-up window to enter a password and after user enters it, the script should use the password to unlock and mount an encrypted ZFS dataset rpool/encrypted . Could you write it for me?
Here's an example of a bash script that creates a pop-up window for entering a password, and then uses the password to unlock and mount an encrypted ZFS dataset:

#!/bin/bash

# Prompt for password
password=$(zenity --entry --title=Enter Password --text=Enter the password for the encrypted dataset:)

# Unlock the dataset using the password
echo $password | sudo zfs receive -o mountpoint=/mnt/encrypted rpool/encrypted

# Check if the dataset was successfully mounted
if mountpoint -q /mnt/encrypted; then
  zenity --info --title=Success --text=The encrypted dataset was successfully mounted.
else
  zenity --error --title=Error --text=The encrypted dataset could not be mounted. Please try again.
fi


In this script, zenity is used to create a pop-up window for entering the password. The sudo zfs receive command is used to unlock and mount the encrypted dataset, and the password is passed to the command using a pipe (|). The mountpoint command is used to check if the dataset was successfully mounted. If the dataset was mounted, a success message is displayed using zenity. If the dataset was not mounted, an error message is displayed.

Note: This script assumes that the ZFS dataset rpool/encrypted has already been created and encrypted. You may need to modify the script to fit your specific setup.
Correct, that's the general idea. Just make sure to replace rpool/encrypted with the actual name of your encrypted ZFS dataset, and modify the mountpoint path as needed.
