How to change the starting directory of a tmux ses

问题:

The directory where you start a tmux session in will be the directory that all new windows will start at.

My question is, how can you change this starting directory without closing your session?

回答1:

The way to do this is to detach from the session (^b d with the default keybindings) and then specify a different directory when you reattach to it. When attaching to a session, use the -c flag to specify the working directory. Here's an example:

$ tmux list-sessions
tmuxwtfbbq: 3 windows (created Tue Apr  5 14:25:48 2016) [190x49]
$ tmux attach-session -t tmuxwtfbbq -c /home/chuck/new_default_directory

This setting will be persisted - after you've reset the working directory, you won't need to keep specifying it every time you reattach to the session.

For the record, I'm on tmux version 2.0 (though I don't think it matters - I couldn't find anything about adding a -c option to the attach-session command in the change logs so I assume it's been there for quite a while).

Chucksmash's answer is a good one, but it can also be achieved without using the session if you like. The command attach-session is also available in the tmux command prompt; and the target session can be specified as the "current" session using a dot.

attach-session -t . -c /path/to/new/directory
