idkrn123 / luks.sh
Created November 19, 2023 01:28
This script provides a user-friendly interface for locking and unlocking LUKS-encrypted volumes. It supports custom mount points, prompts for user input when necessary, and includes robust error handling for a smooth experience. Default actions are provided for ease of use, with the flexibility to specify devices and mount paths as arguments.
#!/bin/bash
# Usage:
# Unlock a LUKS volume with a specified device and default mount path:
# ./luks.sh unlock /dev/sdx1
# Unlock a LUKS volume with a specified device and custom mount path:
# ./luks.sh unlock /dev/sdx1 /mnt/custom_mount
# Lock a LUKS volume with the default mount path:
