# Name: backtunnel-access-tui
|
|
# Summary: Minimal TUI to mount a BackTunnel share into a chosen directory.
|
|
# Description:
|
|
# Interactive, terminal-based helper that asks for remote, tunnel port, and mount point,
|
|
# then invokes backtunnel-access to perform the actual sshfs mount. Defaults to mounting
|
|
# into the selected directory; if non-empty, proposes a "backtunnel" subdirectory.
|
|
#
|
|
# Usage:
|
|
# backtunnel-access-tui <selected-dir>
|
|
#
|
|
# Examples:
|
|
# backtunnel-access-tui ~/Downloads
|
|
#
|
|
# Dependencies:
|
|
# - bash
|
|
# - backtunnel-access (invoked via exec at the end)
|
|
#
|
|
# Exit codes:
|
|
# 0 success (exec replaces the shell on success)
|
|
# 1 invalid usage or mountpoint not writable
|
|
#
|
|
# Notes:
|
|
# - Expands leading "~" in the chosen mount point.
|
|
# - This tool only gathers inputs; mounting is performed by backtunnel-access.
