Resolving doas Sudo Name Changes in Sync with VTMUX on Linux
In Linux, the doas command is an alternative to the popular sudo command. While it can serve as a viable replacement, it may not always be the most useful option, especially when dealing with synchronizing Tmux pane names.
Understanding the Situation
When using the doas command, you may encounter a situation where you've changed the name of a user, and the corresponding Tmux pane name hasn't updated accordingly. This discrepancy can lead to confusion and make it difficult to manage your Linux environment effectively.
Examining the Problem
The main issue lies in the fact that doas does not automatically update Tmux pane names when a user's name is changed. This is because doas and Tmux are not inherently linked, and the latter does not monitor the former for changes in user names.
Proposing a Solution
To resolve this issue, you can create a custom script that updates the Tmux pane name whenever a user's name is changed using the doas command. This script will act as an intermediary between doas and Tmux, ensuring that the pane name remains in sync with the user's name.
Creating the Custom Script
To create the custom script, follow these steps:
- Create a new file called
doas-sync-tmuxusing your preferred text editor, e.g.,nanoorvim. - Add the following code to the file:
#!/bin/bash
# Update Tmux pane name with doas user name
# Get the current doas user name
CURRENT_USER=$(whoami)
# Get the current Tmux pane title
PANE_TITLE=$(tmux display-message -p '#{pane_title}')
# Update the Tmux pane title with the doas user name
tmux set-window-option synchronize-panes on
tmux set-window-title "$CURRENT_USER"
- Save and close the file.
- Make the script executable by running the following command:
chmod +x doas-sync-tmuxImplementing the Solution
Now that you've created the custom script, you can implement it by following these steps:
- Open a new terminal window and start a new Tmux session using the
tmuxcommand. - Create a new pane within the Tmux session using the
Ctrl+B %shortcut. - Run the
doas-sync-tmuxscript in the new pane. - Change the user name using the
doascommand, and observe how the Tmux pane name updates accordingly.

By implementing this custom script, you can ensure that Tmux pane names remain in sync with user names when using the doas command in Linux. This will help maintain a consistent and organized terminal environment, making it easier to manage your system effectively.
