Manipulating terminal groups
|
|
----------------------------
|
|
|
|
Grouping, as the name suggests, allows grouping of terminals allowing
|
|
actions to be taken that affect more than one terminal. As usual,
|
|
following along will help understanding, so lets start with a basic
|
|
window, then split into a 2x2 grid.
|
|
|
|
Let's have another look at the grouping menu for reference, because
|
|
as we proceed, it will change:
|
|
|
|
.. image:: imgs/grouping_01.png
|
|
|
|
The first item **New group...** allows you to create a named group,
|
|
using an editable field that will appear next to the 3-box icon. By
|
|
default this will be given a randomly selected name from the names
|
|
of the Greek alphabet. Here you can see **Phi** was selected:
|
|
|
|
.. image:: imgs/grouping_02.png
|
|
|
|
You can either start typing to replace the provided one with something
|
|
more descriptive, or you can accept the default with ``Return``. For
|
|
the purpose of this document I will just be using default names.
|
|
|
|
If you again click the 3-box/group button, you will see that several
|
|
new entries have been added to the menu:
|
|
|
|
.. image:: imgs/grouping_03.png
|
|
|
|
Because the terminal now has a group the first new entry is **None**
|
|
which will remove the grouping for this terminal.
|
|
|
|
Following that is a list of the known groups, in this case only *Phi*
|
|
so far. This list (plus the *None* entry) can be used to change the
|
|
group of this terminal.
|
|
|
|
Next are two items: **Remove group Phi** and **Remove all groups**.
|
|
You will only get the currently assigned group group as an option to
|
|
remove, as well as an option to remove all groups. This does not
|
|
close the group, but simply removes the group assignments from the
|
|
terminals.
|
|
|
|
The next option is more destructive: **Close group Phi** will exit
|
|
the terminals assigned to this group.
|
|
|
|
Here I've gone ahead and set the upper right terminal to the same
|
|
*Phi* group, and the lower left terminal to a *New group...* of
|
|
**Epsilon**.
|
|
|
|
.. image:: imgs/grouping_04.png
|
|
|
|
A quick glance at the menu again will show that the only change is
|
|
the addition of the *Epsilon* group to the list.
|
|
|
|
To change a group name you can either click on *New group...* again,
|
|
or ``Shift``\ +\ ``click`` on the 3-box/group button, and the editable
|
|
field will reappear.
|
|
|
|
The current terminal is the one with focus. By clicking with key
|
|
modifiers on other terminals 3-box/group button we can speed up group
|
|
organisation. Here's a list of mouse actions (including some already
|
|
detailed):
|
|
|
|
+------------------------------------------------+---------------------------------------+------------------+
|
|
| Action | Mouse | Default Shortcut |
|
|
+================================================+=======================================+==================+
|
|
| Group menu popup | ``click`` | (TBD) |
|
|
+------------------------------------------------+---------------------------------------+------------------+
|
|
| Edit group for terminal | ``Shift``\ +\ ``click`` | (TBD) |
|
|
+------------------------------------------------+---------------------------------------+------------------+
|
|
| Edit group for all terminals in the "group" | ``Shift``\ +\ ``Super``\ +\ ``click`` | (TBD?) |
|
|
+------------------------------------------------+---------------------------------------+------------------+
|
|
| Toggle to current terminals group [1]_ | ``Ctrl``\ +\ ``click`` | |
|
|
+------------------------------------------------+---------------------------------------+------------------+
|
|
| Toggle "group" to current terminals group [1]_ | ``Ctrl``\ +\ ``Super``\ +\ ``click`` | |
|
|
+------------------------------------------------+---------------------------------------+------------------+
|
|
|
|
.. [1] These shortcuts will only work if you use them on terminals
|
|
that are *not* the current terminal.
|
|
|
|
.. warning:: The terminals with no named group are also considered a
|
|
group. If you use one of the ``Super`` shortcuts on a
|
|
terminal with no group, you will also include all the
|
|
other terminals with no group.
|
|
|
|
Skipping slightly ahead in the menu, there are two options that make
|
|
more sense covered here. The **Split to this group** (default: off)
|
|
option means that when you split the current terminal, the new one
|
|
will inherit the group of the current terminal. It is off by default
|
|
in which case new terminals have no group.
|
|
|
|
The second option **Autoclean groups** (default: on) will remove a
|
|
group from the menus group list when the last terminal with that
|
|
group is closed. If off groups will remain in the list until the
|
|
application exits, or the option is enabled.
|
|
|
|
.. note:: Not shown in the above screenshots, there are also menu
|
|
items for grouping all terminals in a tab in the menu. They
|
|
only appear once a new tab is created - **Group all in tab**
|
|
and **Ungroup all in tab**.
|
|
|
|
Some final group related shortcuts are for grouping all terminals
|
|
at once, or grouping terminals in the same tab.
|
|
|

|
Broadcasting input to multiple terminals
|
|
----------------------------------------
|
|
|
|
So first let me describe some terminology (no pun intended).
|
|
**Broadcasting** is the act of sending your input to multiple
|
|
terminals. The current terminal (the one with the red titlebar by
|
|
default) is always the **broadcaster**. Any terminal that is in
|
|
the same group as the current terminal is a potential **receiver**.
|
|
I say potential because the act of broadcasting can be turned on
|
|
and off independently of the grouping.
|
|
|
|
This can be an invaluable time-saver when having to do active
|
|
investigation across multiple machines where you would be repeating
|
|
the same commands on each of them.
|
|
|
|
Terminator's titlebar is colour-coded to help you quickly see which
|
|
terminals are potential receivers, and whether they *will* receive
|
|
the broadcast input.
|
|
|
|
The titlebar is split into two parts. The leftmost part is the
|
|
3-box/group button that has one of three background colours as defined
|
|
in the :ref:`prefs-global` tab of :ref:`preferences`:
|
|
|
|
- *Red* - The current terminal and broadcaster.
|
|
- *Blue* - A terminal that is in the same group as the broadcaster.
|
|
- *Grey* - A terminal in a different group, or no group.
|
|
|
|
The second part consists of the title, and uses the same colouring
|
|
to show the following:
|
|
|
|
- *Red* - The current terminal and broadcaster.
|
|
- *Blue* - A terminal that is acting as a receiver and will duplicate
|
|
input from the broadcaster.
|
|
- *Grey* - A terminal that is not a receiver.
|
|
|
|
There are three settings for broadcasting, selected from the *Group
|
|
menu*. Following are an image of each of these modes, with ``test``
|
|
typed into the current broadcasting terminal:
|
|
|
|
- *Broadcast off*
|
|
|
|
.. image:: imgs/broadcast_01.png
|
|
|
|
Here you can see that only the current terminal receives input, even
|
|
though the upper right terminal is also a part of the *Phi* group.
|
|
|
|
- *Broadcast all*
|
|
|
|
.. image:: imgs/broadcast_02.png
|
|
|
|
Here you can see that all terminals, including those in other groups,
|
|
or with no group, receive the input.
|
|
|
|
- *Broadcast group* (default mode; can be changed in the
|
|
:ref:`prefs-global` tab of :ref:`preferences`.)
|
|
|
|
.. image:: imgs/broadcast_03.png
|
|
|
|
Here you can see that only the terminal(s) in the same group in the
|
|
same group as the broadcaster receive input.
|
|
|
|
Be careful with additional tabs, windows, or when you are zoomed or
|
|
maximised on a single terminal. Just because you cannot see a terminal
|
|
does not mean the terminal is not receiving. This can cause problems
|
|
if you are typing a destructive command without realising that this
|
|
command is going to other terminals.
|
|
|
|
Those with good eyesight may have spotted the other visual indicator
|
|
of the colours in the 3-box icon changing for the different status of
|
|
the terminals too. When you are zoomed or maximised, the presence of
|
|
blue in this icon might be the only visual indicator of receivers.
|
|
|
|
As with all things in Terminator, we have shortcuts to help you keep
|
|
your hands on the keyboard:
|
|
|
|
+-----------------+-------------------+
|
|
| Action | Default Shortcut |
|
|
+=================+===================+
|
|
| Broadcast off | ``Alt``\ +\ ``O`` |
|
|
+-----------------+-------------------+
|
|
| Broadcast all | ``Alt``\ +\ ``A`` |
|
|
+-----------------+-------------------+
|
|
| Broadcast group | ``Alt``\ +\ ``G`` |
|
|
+-----------------+-------------------+
|
|
|
|
.. warning:: It has become apparent that IBus causes problems with
|
|
broadcast input. When multiple keystrokes are used to
|
|
*compose* a letter, such as the ``AltGr``\ +\ ``[``
|
|
followed by ``a``\ , ``o``\ , ``u`` keys to get **ä**,
|
|
**ö**, **ü** characters for the German language.
|
|
|
|
Instead of getting your composed letter in all receivers,
|
|
you will only get the composed letter in the current
|
|
terminal. If you copy and paste the character into the
|
|
current terminal then it will be input into the
|
|
receivers.
|
|
|
|
You may not even realise that you are running IBus.
|
|
Killing it will temporarily fix the problem. There is
|
|
a fix for IBus and VTE, but only in the newer builds of
|
|
VTE. For that we would need the experimental GTK3
|
|
version of Terminator.
|
|

Insert terminal number

|
|
|
|
The last two menu items are slightly out of place here. They are the
|
|
same function as the shortcuts mentioned :ref:`here <insert-termnum_shortcut>`.
|
|
They were added early on when the broadcast feature was added, and
|
|
the argument could be made for removing them. So far no-one has
|
|
though, so for now they will stay here.
