Let us say it frankly: TMUX is a great console tool!
TMUX is a terminal multiplexer, allowing a user to access multiple separate terminal sessions inside a single terminal window or remote terminal session: like GNU Screen, but with more features and distributed under a BSD-like.
One of the most used feature of terminal multiplexers is “persistence”, that allows the user to start applications from one computer, and then reconnect from a different computer and continue using the same application without having to restart it.
The process of re-attach usually is manual: once reconnected, the user needs to restart tmux and re-attach the session.
I think could be really useful automatize this operation, so i want to share this simple code snippet, that could be appended to bash configuration file (.bashrc):
if [[ "$TMUX" == "" ]] && [[ "$SSH_CONNECTION" != "" ]]; then WHOAMI=$(whoami) if tmux has-session -t $WHOAMI 2>/dev/null; then tmux -2 attach-session -t $WHOAMI else tmux -2 new-session -s $WHOAMI fi fi
The script simply attempts to discover a detached session and attach it, else create a new session.
