# How to share a tmux session accross users?

It can be handy to share a tmux session between different user accounts, for
example to allow a someone to look over your shoulder while you work on
something.

To do this, we need to have a folder with group permission shared between the
two persons.

In the Fedora infrastructure we can easily use the ``fi-apprentice`` group for
this.

So we have created the folder:

* ``/var/tmux/``  which is writable for both the ``fi-apprentice`` and
  ``sysadmin`` groups


You can then create a tmux session using:

```
  tmux -S /var/tmux/<socket name> new -s <session name>
```
(The socket and session names can be different, but they don't have to)

And the other person(s) can join it using:

```
  tmux -S /var/tmux/<socket name> att -t <session name>
```

Once the person who created the shared session stops it, the people who have
joined will be kicked out of the session as well.
