#!/usr/bin/env sh
# Description: Toggle mount status of a device using pmount
# If the device is not mounted, it will be mounted.
# If the device is mounted, it will be unmounted and powered down.
#
# Dependencies: lsblk, pmount (optional), udisks2
#
# Usage: Runs `lsblk` on 'l', exits on 'Return`.
#
# Notes:
# - The script uses Linux-specific lsblk to list block devices. Alternatives:
# macOS: "diskutil list"
# BSD: "geom disk list"
# - The script uses udisksctl (from udisks2) to power down devices. This is also Linux-specific.
# Users on non-Linux platforms can comment it and use an alternative to power-down disks.
#
# Shell: POSIX compliant
# Author: Arun Prakash Jana
