Manage dtach sessions via a simplistic menu. (dtach is like screen, but much simpler for the 90% use case.)

menu.sh

#!/bin/sh

# Provides a listing of your ~/.dtach folder to
# remind you what sessions exist; enter the name
# of a session (sans .dtach suffix) to reconnect,
# or a new name to start a new session.

# If an executable exists in ~/.dtach with the same
# name as the session plus an .auto suffix, it will
# be run instead of the shell.

D=~/.dtach

cd ~

echo "Current Sessions:"
echo "================="

ls -la --color "$D"

echo ""
echo -n "Choice: "

read session

SOCKET=$D/$session.dtach
AUTO=$D/$session.auto

test -e "$AUTO" || AUTO=$SHELL
exec dtach -A "$SOCKET" "$AUTO"

menuloop.sh

#!/bin/sh

# Invoke menu.sh in a loop

# My usecase: SSHing into home computer via ConnectBot
# on my tablet. ConnectBot only supports one connection
# to a host at a time, and wifi can always drop. Setting
# ConnectBot to run this on every connection lets me easily
# multiplex shells and recover from connection drops.
# I have a vnc.auto script to launch x11vnc, since
# I remote-desktop a lot.
