# 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.
|
|
#
|
|
# Note: The script uses Linux-specific lsblk to list block devices. Alternatives:
|
|
# macOS: "diskutil list"
|
|
# BSD: "geom disk list"
|
|
#
|
|
# Shell: POSIX compliant
