How to Personalize Your Bash Prompt: Add Info, Colors, and Multi‑Line Layouts

When you open a Linux shell you see a default Bash prompt like

[user@host ~]$

. This article shows how to customize that prompt to display useful information, colors, and multiple lines.

How to Set the Bash Prompt

The prompt is defined by the environment variable

PS1

. For multi‑line prompts,

PS2

is used.

<code>export PS1="[Linux Rulez]$ "
export PS2="... "
if true; then
... echo "Success!"
... fi
Success!</code>

Where to Define PS1

The default value is set in

/etc/bashrc

. To customize, add your settings to

~/.bashrc

instead of modifying the system file.

Common Escape Sequences

\u

: username

\h

: short hostname

\W

: current directory basename ("~" for home)

\s

: shell name (bash or sh)

\v

: shell version

Additional Useful Sequences

\d

: date (e.g., "Tue Jun 27")

\D{fmt}

: custom date format (see

strftime

)

\D{%c}

: localized date and time

\n

: newline (for multi‑line prompts)

\w

: full current working directory path

\H

: full hostname

Multi‑Line Prompt Example

Use

\n

to split the prompt into two lines, showing date, time, and directory on the first line and user/host on the second.

<code>PS1="\D{%c} \w\n[\u@\H]$ "</code>

Adding Colors

Colors can be added with ANSI escape codes. Below is an example that colors the date red, the directory cyan, and the username with a yellow background.

For more color codes, refer to the "Bash prompt HOWTO" documentation.
