4 cool terminal multiplexers
|
||
======
|
||
|
||
![][1]
|
||
|
||
The Fedora OS is comfortable and easy for lots of users. It has a stunning desktop that makes it easy to get everyday tasks done. Under the hood is all the power of a Linux system, and the terminal is the easiest way for power users to harness it. By default terminals are simple and somewhat limited. However, a _terminal multiplexer_ allows you to turn your terminal into an even more incredible powerhouse. This article shows off some popular terminal multiplexers and how to install them.
|
||
|
||
Why would you want to use one? Well, for one thing, it lets you logout of your system while _leaving your terminal session undisturbed_. It’s incredibly useful to logout of your console, secure it, travel somewhere else, then remotely login with SSH and continue where you left off. Here are some utilities to check out.
|
||
|
||
One of the oldest and most well-known terminal multiplexers is _screen._ However, because the code is no longer maintained, this article focuses on more recent apps. (“Recent” is relative — some of these have been around for years!)
|
||
|
||
### Tmux
|
||
|
||
The _tmux_ utility is one of the most widely used replacements for _screen._ It has a highly configurable interface. You can program tmux to start up specific kinds of sessions based on your needs. You’ll find a lot more about tmux in this article published earlier:
|
||
|
||
> [Use tmux for a more powerful terminal][2]
|
||
|
||
Already a tmux user? You might like [this additional article on making your tmux sessions more effective][3].
|
||
|
||
To install tmux, use the _sudo_ command along with _dnf_ , since you’re probably in a terminal already:
|
||
|
||
```
|
||
$ sudo dnf install tmux
|
||
```
|
||
|
||
To start learning, run the _tmux_ command. A single pane window starts with your default shell. Tmux uses a _modifier key_ to signal that a command is coming next. This key is **Ctrl+B** by default. If you enter **Ctrl+B, C** you’ll create a new window with a shell in it.
|
||
|
||
Here’s a hint: Use **Ctrl+B, ?** to enter a help mode that lists all the keys you can use. To keep things simple, look for the lines starting with _bind-key -T prefix_ at first. These are keys you can use right after the modifier key to configure your tmux session. You can hit **Ctrl+C** to exit the help mode back to tmux.
|
||
|
||
To completely exit tmux, use the standard _exit_ command or _Ctrl+D_ keystroke to exit all the shells.
|
||
|
||
### Dvtm
|
||
|
||
You might have recently seen the Magazine article on [dwm, a dynamic window manager][4]. Like dwm, _dvtm_ is for tiling window management — but in a terminal. It’s designed to adhere to the legacy UNIX philosophy of “do one thing well” — in this case managing windows in a terminal.
|
||
|
||
Installing dvtm is easy as well. However, if you want the logout functionality mentioned earlier, you’ll also need the _abduco_ package which handles session management for dvtm.
|
||
|
||
```
|
||
$ sudo dnf install dvtm abduco
|
||
```
|
||
|
||
The dvtm utility has many keystrokes already mapped to allow you to manage windows in the terminal. By default, it uses **Ctrl+G** as its modifier key. This keystroke tells dvtm that the following character is going to be a command it should process. For instance, **Ctrl+G, C** creates a new window and **Ctrl+G, X** removes it.
|
||
|
||
For more information on using dvtm, check out the dvtm [home page][5] which includes numerous tips and get-started information.
|
||
|
||
### Byobu
|
||
|
||
While _byobu_ isn’t truly a multiplexer on its own — it wraps _tmux_ or even the older _screen_ to add functions — it’s worth covering here too. Byobu makes terminal multiplexers better for novices, by adding a help menu and window tabs that are slightly easier to navigate.
|
||
|
||
Of course it’s available in the Fedora repos as well. To install, use this command:
|
||
|
||
```
|
||
$ sudo dnf install byobu
|
||
```
|
||
|
||
By default the _byobu_ command runs _screen_ underneath, so you might want to run _byobu-tmux_ to wrap _tmux_ instead. You can then use the **F9** key to open up a help menu for more information to help you get started.
|
||
|
||
### Mtm
|
||
|
||
The _mtm_ utility is one of the smallest multiplexers you’ll find. In fact, it’s only about 1000 lines of code! You might find it helpful if you’re in a limited environment such as old hardware, a minimal container, and so forth. To get started, you’ll need a couple packages.
|
||
|
||
```
|
||
$ sudo dnf install git ncurses-devel make gcc
|
||
```
|
||
|
||
Then clone the repository where mtm lives:
|
||
|
||
```
|
||
$ git clone https://github.com/deadpixi/mtm.git
|
||
```
|
||
|
||
Change directory into the _mtm_ folder and build the program:
|
||
|
||
```
|
||
$ make
|
||
```
|
||
|
||
You might receive a few warnings, but when you’re done, you’ll have the very small _mtm_ utility. Run it with this command:
|
||
|
||
```
|
||
$ ./mtm
|
||
```
|
||
|
||
You can find all the documentation for the utility [on its GitHub page][6].
|
||
|
||
These are just some of the terminal multiplexers out there. Got one you’d like to recommend? Leave a comment below with your tips and enjoy building windows in your terminal!
