I don’t like my prompt, i want to change it. it has my username and host, but the formatting is not what i want. This blog will get you started quickly on doing exactly that.
This is my current prompt below:



To change the prompt you will update .bashrc and set the PS1 environment variable to a new value.

Here is a cheatsheet of the prompt options:

You can use these placeholders for customization:

\u – Username

\h – Hostname

\w – Current working directory

\W – Basename of the current working directory

\$ – Shows $ for a normal user and # for the root user

\t – Current time (HH:MM:SS)

\d – Date (e.g., "Mon Jan 05")

\! – History number of the command

\# – Command number


I want to change my prompt to say

Here is my new prompt I am going to use:

export PS1="linuxhint@mybox \w: "


Can you guess what that does? Yes for my article writing this is exactly what i want. Here is the screenshot:



A lot of people will want the Username, Hostname, for my example i don’t! But you can use \u and \h for that. I used \w to show what directory i am in. You can also show date and time, etc.

You can also play with setting colors in the prompt with these variables:

Foreground Colors:

\e[30m – Black

\e[31m – Red

\e[32m – Green

\e[33m – Yellow

\e[34m – Blue

\e[35m – Magenta

\e[36m – Cyan

\e[37m – White



Background Colors:

\e[40m – Black

\e[41m – Red

\e[42m – Green

\e[43m – Yellow

\e[44m – Blue

\e[45m – Magenta

\e[46m – Cyan

\e[47m – White

Reset Color:

\e[0m – Reset to default


Here is my colorful version. The backslashes are primarily needed to ensure proper formatting of the prompt and avoid breaking its functionality.

export PS1="\[\e[35m\]linuxhint\[\e[0m\]@\[\e[34m\]mybox\[\e[0m\] \[\e[31m\]\w\[\e[0m\]: "




This uses Magenta, Blue and Red coloring for different parts of the prompt.
