Introduction
Hello everyone, today I would like to share about “Tmux Guide” . I hope my following guide will be helpful to everyone.
Description problem
If you have ever worked on a Linux server, you must have experienced running commands that take a lot of time to complete (e.g., running an SQL query for an ad-hoc report on psql). During this time, you have to wait and maintain the connection from your local machine (SSH into the server) until the process is finished. If the network is unstable and the connection between your local machine and the server gets interrupted, you have to start all over again.
The simplest solution here is that you can run the command in the background by appending ”&” to the end of the command. However, with this approach, you won’t be able to monitor the running process.
Instead, we will use an execellent tool, that is Tmux.
What is Tmux ?
Tmux is a terminal multiplexer, which means it allows you to manage multiple terminal sessions from a single window. This is useful for multitasking and organizing your work in the terminal.
Installing Tmux
On Ubuntu Linux:
sudo apt install tmuxOn CentOS Linux:
yum install tmuxOn macOS:
brew install tmuxUsing Tmux
Create new session
tmux new -s <session_name>Example: I will run the following command to create a session named tuandata
tmux new -s tuandataDetach session
To detach session, you press Ctrl b, followed by d
Attach session
To attach session, you run the following command
tmux a -t <session_name>Example: I will run the following command to attach a session named tuandata
tmux a -t tuandataShow windows list in session
To show all windows in a session, in the session terminal, you press Ctrl b then press w.
Here, you can move to window you want (by using arrow keys to select the window and then pressing Enter)
Create new window in session
To create new window in session, in the session terminal, you press Ctrl b then press c
Imediately, a new window is created, and you are at it.
Rename window
To rename a window, in the terminal session of that window, press Ctrl b then ,.
The window name will appear editable. Remove the old name and type the new name you want.
Finally, press Enter to apply the rename.
Kill window
To kill a window, in the terminal session of that window, press Ctrl b then Shift 7.
At the bottom terminal session, an alert will apear with the message kill-window windown_name? (y/n) to confirm the action of killing the window.
If you still want to kill the window, press y; otherwise, press n.
Show list of sessions
To show the list of sessions, you run the following command
tmux lsKill session
To kill a session, you run the following command
tmux kill-sess -t <session_name>Example: I will run the following command to kill the session named tuandata
