mux

Create a new muxer with a specified name

$ mux -c [muxer_name1 muxer_name2 ...]

$ mux -s [size]

$ mux -i [input_muxer_name]

$ mux -o [output_muxer_name]

The 'mux' command is not a standard Linux utility. If you are referring to a terminal multiplexer, commands like tmux or screen are commonly used.

The term "mux" is not a standard, standalone Linux command found in most distributions. It is commonly used as an abbreviation for "multiplexer" or "multiplexing." In the context of Linux, "mux" most often informally refers to terminal multiplexers such as tmux or GNU Screen.

These powerful utilities allow users to manage multiple independent terminal sessions within a single window. They enable users to:
- Detach from a session and reattach later, even after network disconnections or logging out, keeping processes running in the background.
- Create multiple windows or panes within a single terminal window, each running a different command or process.
- Share terminal sessions with other users for collaborative work.

While highly valuable for development, system administration, and managing long-running tasks, remember that executing "mux" directly will typically result in a "command not found" error, as it's not an executable command itself.

It's crucial to understand that 'mux' itself is not a predefined command in most standard Linux distributions. Its usage implies either a custom script named 'mux' or, more commonly, an informal reference to terminal multiplexing software like tmux or GNU Screen. Attempting to execute 'mux' directly will likely result in a 'command not found' error unless a specific alias or script has been set up on the system.

A terminal multiplexer is a software application that allows a user to create and control multiple virtual terminals or 'panes' within a single physical terminal window. Key functionalities include:
- Session Persistence: Detach from a session and reattach later, even from a different machine, keeping processes running in the background.
- Multiple Windows/Panes: Divide the terminal into multiple independent windows or panes, each running a different command or process.
- Shared Sessions: Allow multiple users to connect to and interact with the same terminal session collaboratively.
These tools are invaluable for remote work, long-running processes, and organizing complex command-line workflows.

The concept of a 'multiplexer' (often abbreviated 'mux') has roots in electronics and telecommunications, referring to a device that selects one of several analog or digital input signals and forwards the selected input into a single output line. In computing, this concept extends to software that allows multiple sessions or processes to share a single terminal interface or network connection. While the term 'mux' isn't a command, it historically influenced the naming and development of utilities like GNU Screen (first released in 1987) and later tmux (released in 2007), which popularized terminal multiplexing on Unix-like systems, enabling persistent terminal sessions and organized workflows.
