* plugins/nmount: keep `while` & `do` on one line for consistency * plugins/nmount: sync only that device, which user wants to unmount * plugins/nmount: replace all instances of `$dev` with `/dev/$dev` * plugins/nmount: add `--no-user-interaction` option to `udisksctl` Otherwise the user will be asked for authentication each time he wants to unmount, say, HDD, since `udisksctl` will try to power it off. * plugins/nmount: try to mount only existing block devices * plugins/nmount: do not invoke `lsblk` immediately after mounting Sometimes `lsblk` fails to provide mountpoint in such a short time frame. * plugins/nmount: simplify pipe * plugins/nmount: keep `echo` arguments in a single pair of quotes * plugins/nmount: report mountpoint only if mounting was successful

# 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
|
|
#
|
|
# 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 alterntive to power-down disks.
|
|
#
|
|
# Shell: POSIX compliant
|
