# Description: Autodetects a nnn remote mountpoint (mounted with `c`)
|
||
|
|
# from any of its subfolders and allows unmounting it
|
||
|
|
# from the subdir without navigating to the mountppoint
|
||
|
|
# or entering the remote name. Also works when hovering
|
||
|
|
# the mountpoint directly like vanilla `u`.

# Dependencies: fusermount

# Tried `printf "%s" "0c$m" > "$NNN_PIPE"` but it breaks the nnn interface, see #854.
