// tmux is an alternative to [[screen]] //

with the help of tmux you can
  * start multiple shell sessions in one window
  * keep interactive shell sessions running in the backround
  * work together in a shell
  * execute several commands in parallel

^ start                                       ^^
| start a tmux-session                           | ''tmux'' |
| move a tmux session to the background          | ''Ctrl+b'' ''d'' |
| move a tmux session into forground             | ''tmux attach'' |
| end a shell                                    | ''Ctrl+d'' |
^ sessions                           ^^
| start a named session 'session1'               | ''tmux new -s session1'' |
| list sessions                                  | ''tmux list-sessions'' |
| connect to running session ''session1''        | ''tmux attach -t session1'' |
^ windows                              ^^

| list windows                                   | ''Ctrl+b'' ''w'' |
| jump to window 4                               | ''Ctrl+b'' ''4'' ([0..9])  |
^ panes                                          ^^
| split horizontaly                              | ''Ctrl+b'' ''%%"%%'' |
| split verticaly                                | ''Ctrl+b'' ''%'' |
| change to other pane                           | ''Ctrl+b'' ''<Pfeil>'' |
| remove current pane                            | ''Ctrl+b'' ''x'' |
| change the size of the current pane            | ''Ctrl+b'' ''Ctrl+<Pfeil>'' |
| change current pane to full-screen and back    | ''Ctrl+b'' ''z''  |
| change all panes to verticaly same size        | ''Ctrl+b'' ''Alt+2'' bzw.''Ctrl+b'' ''ESC'' ''2'' | 
| change all panes to horizontally same size     | ''Ctrl+b'' ''Alt+1'' bzw.''Ctrl+b'' ''ESC'' ''1'' | 
^ scroll                                         ^^

| turn scrolling off                             | ''Ctrl+c''  |

====== Reloading tmux config ======
If you have made changes to your tmux configuration file in the ~/.tmux.conf file, 
it shouldn’t be necessary to start the server up again from scratch with kill-server. 
Instead, you can prompt the current tmux session to reload the configuration with the source-file command.

This can be done either from within tmux, by pressing Ctrl+B and then : to bring up a command prompt, and typing:

<file>
:source-file ~/.tmux.conf
</file>

Or simply from a shell:

<file>
$ tmux source-file ~/.tmux.conf
</file>

This should apply your changes to the running tmux server without affecting the sessions or windows within them.

====== Distributed shell ======
have input in all panes:
  * ''<Ctrl>+b''

  :set synchronize-panes
switch it off again:
  :set synchronize-panes off

====== ''Ctrl+a'' instead of ''Ctrl+b'' ======
<file>
# Ctrl+a statt Ctrl+b
set -g prefix C-a
unbind-key C-b
bind-key C-a send-prefix
</file>
