|
||||
Attach to an existing tmux session, or bootstrap a new session.
|
||||
|
||||
If no session exists which fits the criteria, this will create a new one and
|
||||
load it up obeying the commands contained in the FILE argument passed in. It
|
||||
must contain commands which are tmux-command compatible since they will be
|
||||
passed to tmux unmodified. If a session exists and a valid configuration FILE is
|
||||
passed, it will attach itself to the session and execute the session setup inside.
|
||||
|
||||
It will load the default tmux.conf in the following order:
|
||||
- XDG_CONFIG_HOME/tmux/tmux.conf (usually ~/.config/tmux/tmux.conf)
|
||||
- ~/.tmux.conf
|
||||
- /etc/tmux.conf
|
||||
Afterwards, it will apply the contents of the FILE argument passed into the command.
|
||||
|
||||
If no FILE argument is passed it will create an empty session, or attach itself to
|
||||
the session specified.
|
||||
|
||||
If no NAME argument is passed it will automatically create a session name from the
|
||||
FILE argument passed.
|
||||
|
||||
If creating a new session without passing in a FILE argument, and the current directory
|
||||
contains a .tmux.session file, it will automatically use that to set up the session.
|
||||
|
||||
By default, it also looks for valid session files in XDG_CONFIG_HOME/tmux/sessions/
|
||||
This path can be changed by setting the TM_SESSION_PATH environment variable.
