# 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.
|
|
#
|
|
# Runs `lsblk` if 'l' is entered, exits on 'Return`.
|
|
#
|
|
# Note:
|
|
# - 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 pwoer down devices. This is also Linux-specific.
|
|
# Users on non-Linux platforms can comment it and use an alterntive to power-down disks.
|
|
#
|
|
# Shell: POSIX compliant
