This is my documentation on how to use tmux which is a tool that allows users to run multiple tasks within a single window.

Knowledge

#

Similar to the previous blog post, this is an addon to the Linux command-line (Bash). Ubuntu and Kali Tool are recommended for this challenge.

tmux Commands

Walkthrough

#

Task 1

#

Firstly, you must install tmux into your linux system. This could be done through using the following command:

  sudo apt-get install tmux

You will be asked your password in order to continue the installation.

Task 2

#

After installation, you are now able to use tmux. When using the following command:

  tmux

It will open the tmux software, which is essentially another terminal but more available functions such as multitasking.

Task 3

#

All tmux commands start with two keyboard combinations. The first keyboard combination key is:

  Control

Task 4

#

The second keyboard combination key is:

  B

Task 5

#

To detach a session, firstly you press the two combination keys of “Control + B”, follow by the key:

  D

What detaching does is similar in creating new windows in a internet browser. This would create multiple sessions and can be used later by “tabbing” through using “Control + B” followed by either the ‘(’ or ‘)’ key. Make sure to use the shift key.

Task 6

#

To list all your windows or sessions, you use the command:

  tmux ls

Task 7

#

By default; without setting the session name, the names will begin from:

  0

The numbers will increase as more sessions are created.

Task 8

#

To choose the session that you just created, you use the command:

  tmux a -t 0

If you want to use a specific session, replace the “0” in the above command with the name of your session that is listed with the “tmux ls” command.

Task 9

#

To create a new window within a session, firstly you press the two combination keys of “Control + B”, follow by the key:

  C

Creating a new window within a session is essentially creating a “tab” within an internet browser. You are able to “tabbing” through using “Control + B” followed by either the ‘N’ or ‘P’ or ‘0-9’ keys.

Task 10

#

Does not exist.

Task 11

#

Does not exist.

Task 12

#

When your tmux terminal is filled, you should use “Copy Mode” in order to scroll up and down. Firstly you press the two combination keys of “Control + B” followed by the key:

  [

Task 13

#

As of February 2020, the key does not go to the very top.

  g

Task 14

#

As of February 2020, the key does not go to the very bottom.

  G

Task 15

#

To quit “Copy Mode” you use the key:

  q

Task 16

#

To split windows vertically, you press “Control + B” followed by the key:

  %

Task 17

#

To split windows horizontally, you press “Control + B” followed by the key:

  "

Task 18

#

Does not exist.

Task 19

#

Does not exist.

Task 20

#

Does not exist.

Task 21

#

To remove a pane, you press “Control + B” followed by the key:

  X

Task 22

#

To close the tmux session, it can be done by typing within the command-line:

  exit

Task 23

#

To create new sessions with a name of “neat” you type within the command-line:

tmux new -s neat

Conclusion

#

In short; to cut down all the learning, I believe that the most useful commands would be:

• tmux:
  • To initiate it within the Linux command-line.
• CTRL + B + [RELEASE] + %:
  • Split the window vertically.
• CTRL + B + [RELEASE] + &:
  • Split the window horizontally.
• CTRL + B + [RELEASE] + (ARROW KEYS):
  • Swap between panels.
• CTRL + B + [RELEASE] + C:
  • Create new tab.
• CTRL + B + [RELEASE] + N/P:
  • Move to next/previous tab.
• exit:
  • To close a tmux window or exit out of tmux.

After learning this add-on within the Linux command-line, it has increased my productivity as I can monitor multiple tasks within one window. It is most definitely faster than “Alt-Tabbing” and it is quick to learn.
