# Description: Toggle mount status of a device using pmount

|
|
|
|

# 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"
|
2021-06-02 01:58:01 -04:00
|
|
|
# - 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 alterntive to power-down disks.
