How to change the prompt in Linux?

The default prompt will be

<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="44362b2b3004292b2a31">[email protected]</a> dev]#

Can we change the “[email protected]” part and give it a desired name?

Method 1

This is changed by changing the environment variable PS1.

You can see the current value of PS1 by:

[email protected] dev# echo $PS1

You can see the value to be equal to [email protected]h w$, where:

u : username
h : hostname
w : current working directory
$ : a # symbol for the root user, a $ symbol for other users

If you want the change to be permanent, you have to add the script changing the value of PS1 in ~/.bashrc, since that it gets executed every time a user logs in.

Method 2

This depends on your shell. As an important side note, you should never use the root account as a personal account. Create a normal user and set up access to sudo. Please check your distribution manual as to how to do this.

In zsh, you need to set the PROMPT variable like so:

PROMPT='%{ESC[38;5;24m%};%{ESC[0m%} '

zshell offers a lot of other options and this is really a minimal prompt.

In bash, you can set it this way:

local ROOK="[33[38;5;24m]"
local DEFAULT="[33[0;39m]"
PS1="${ROOK}$${DEFAULT} "

Note that in both cases, I have a 256 colour enabled terminal. The man page will help a lot (man bash or man zsh).
