I’ve been in a fight with tmux on how to create new session under certain name, but if it already exists to attach to that current one for a very long time. Reason for that was that when I’m connecting to the remote servers I usually have my own session under certain name there and I’d like to attach to that existing one if it already exists.
Connecting to the server then issuing:
and deciding upon that should I issue:
tmux new -s Ivan
tmux a -t Ivan
is tiresome, especially when there are many active sessions already.
Today, I finally found magic combination of switches by looking at tmux man page:
tmux new -As Ivan
This will create new session with name “Ivan”, but if that session already exists then
-A switch will behave like an
attach-session command, and end result will be attaching to the existing session under that name instead of creating new one or throwing an error.
