mac terminal computer name is garbled
When I use terminal enter zsh, my computer name is garbled, n3-85-8 instead MacBook-Pro. Sometime so as the bash. Do anyone know why? And how to fix it.
Solution
There are two effects happening here:
- Bash only reads the hostname (as displayed in the prompt) once at shell startup, which means you only see the change when you start a new shell, not when your hostname changes.
- macOS by default changes its own hostname based on the network configuration
You can configure your computer not to change its hostname (see for example this question). Or, you can configure bash to use the computer's persistent LocalHostName in the prompt. This value does not change when you connect to a different network.
You can edit your ~/.bashrc (or related file) to have a line like:
PS1=$(scutil --get LocalHostName)':\W \u\$'
- increment a column and line number value using bash
- 10 second delay between login and shell prompt.
